NVScene 2008 Session: Rendering Worlds with Two Triangles - Raytracing on the GPU (Iñigo Quilez) NVScene 2016-04-26 | Video recorded and edited by Jim Leonard (Trixter/Hornet).With the introduction of powerful shaders, long unused techniques from the past are due to return: the use of raytracing allows programmers to implement various optical effects that are difficult or not possible with standard rasterizing methods. This talk will reveal the details about the implementation of such routines and the possible pitfalls to avoid.
NVScene 2008 Session: Exploring Chunks of Time in Linger In Shadows (Michal Staniszewski) NVScene 2016-04-26 | Video recorded and edited by Jim Leonard (Trixter/Hornet).Demos often take advantage of their constant flow, usually relying on static geometry, pre-baked lighting and fixed camera paths. Plastic's Linger In Shadows, besides being the world's first demo on the PlayStation 3, holds a distinction of providing an interactive mode for the users to explore. This presentation will detail the growth of complexity in the demo, where the main controlling aspect is time.
NVScene 2008 Session: From .kkrieger to debris. - Procedural Content Generation (Dierk Ohlerich) NVScene 2016-04-26 | Video recorded and edited by Jim Leonard (Trixter/Hornet).Procedural content generation has been creeping in slowly into commercial entertainment software, even though it has been in heavy use in the demoscene for more than a decade now. This talk will present the full power of algorithmic content, used to produce the infamous 96 kilobyte first-person shooter .kkrieger.
NVScene 2008 Session: Deconstructing Demos - From Conception to Performance (Konstantinos Pataridis) NVScene 2016-04-26 | Video recorded and edited by Jim Leonard (Trixter/Hornet).The seminar is all about the creation of demos, from the original idea up to the actual implementation with an emphasis on production and direction instead of code, modeling and sound.The flow of the seminar follows the creation of an imaginary demo: from the original concept and the sequencing of scenes to solving problems such as mixing visuals and sound and managing the process on a tight timescale. These issues are fundamental in the creation of demos of all levels, and as such, the seminar is aimed at novice and experienced audience alike.
NVScene 2008 Session: Understanding Realtime as Design Potential (Thomas Mann) NVScene 2016-04-26 | Video recorded and edited by Jim Leonard (Trixter/Hornet).While realtime demos have been traditionally a programming-oriented artform, in recent years, with the introduction of WYSIWYG-demotools, graphic artists have claimed a larger slice in the creation process. The seminar will detail a designers point of view on understanding the limitations and advantages of realtime visuals.
NVScene 2008 Session: The Other Side of Demo Programming (Martti Nurmikari) NVScene 2016-04-26 | Video recorded and edited by Jim Leonard (Trixter/Hornet).Demo coding is often claimed to rely on "The Idea", with people often disregarding the actual software design process of implementing a concept as secondary. This talk shall elaborate on the methods of both approximating an idea through code, and creating an idea with an implementation in mind.
NVScene 2014 Session: Multi platform Graphics Done Right (Bent Stamnes) NVScene 2016-04-25 | Since 2011, Outracks Technologies has been developing two unique pieces of technology: a new programming language ("Uno") and a toolsuite ("Realtime Studio"). Both have been designed to bring wow-factor, productivity and unparalleled portability to mainstream app development on mobile, the web and native platforms - with a special focus on graphics programming. Uno unites graphics code and logic code into a single high-level language, and this talk is an introduction to Realtime Studio and its benefits for developers and artists alike.Bent Stamnes has been involved with real-time graphics since he became a demoscener in 1989. He has served as senior editor for the digital magazine ZINE, and is the founder of the cross-platform digital creation community Displayhack.org, as well as the co-author of the book "Demoscene: The Art of Real-Time". He has been a featured speaker on real-time graphics and the demoscene at the FMX conference on Animation, Effects, Games and Interactive Media since 2005, and at other conferences such as FITC Amsterdam and Toronto.
NVScene 2014 Session: Demo Engine Tricks of the Trade (Armin Jahanpanah) NVScene 2016-04-25 | Note: This recording is unfortunately incomplete. However, we decided to upload what we had anyway, because some of it is better than none of it. :)This talk will present practical techniques to improve productivity and foster the creativity of the demo-making process as well as performance optimization tips. The main mantra is to reduce complexity and use simple solutions rather than over-engineering when faced with practical problems. Hands-on code snippets will be used to illustrate how shorter turnaround times for asset tweaking can be achieved, rendering performance improved and engine architecture simplified. Less complexity, simpler code - more impact!Since first experiencing early Amiga demos in the 1990s, Armin became hooked to the wonderful world of graphics programming. He started his demoscene activities in 1997, when texture mapping was all the rage. After finishing university in 2006, he worked at NEC R&D in the area of multicore technology and graphics rendering techniques. Currently he works at Bytec as a senior software engineer for medical devices where he needs to make sure his code doesn't crash during eye surgery.
NVScene 2014 Session: A Short History of Hardware Abuse (Michael Dille and Derek Kozel) NVScene 2016-04-25 | Since the very beginning of computer graphics and the demoscene, using hardware in ways their designers didn't intend has been at the core of making cool stuff. Nowadays, one might immediately think of all the purposes for which GPUs are used, but the theme goes back to the origins of the field. We'll talk about a few machines from the early years of home computing that squeezed impressive graphics abilities from very simple hardware designs and some of the ways demo hackers squeezed still more. Case studies will be drawn from the huge retro hardware collection our demo group maintains. We will also cover a few more modern examples from the Maker movement.Dr. Dille is a Sr. Computer Scientist at SGT/NASA Ames Research Center, where he works on prototype planetary exploration rovers. In his spare time, he tinkers with FPGA-based hardware to emit HDMI from classic 80s home computers. Mr. Kozel is an embedded systems engineer currently finishing a Masters at Carnegie Mellon University Silicon Valley with an interest in high performance code and radio systems. Both are core members of cmucc, an American demo group that sports several first place compo entries and organizes the Demosplash party at Carnegie Mellon University in Pittsburgh, Pennsylvania.
NVScene 2014 Session: New Ideas and Techniques For Creating Real time Imagery (Inigo Quilez) NVScene 2016-04-25 | The demoscene has a lot to do about fighting limitations, either platform-related or artificial and self-imposed ones. Under the constraints of such limitations, it is not surprise that we reach for novel ways of thinking and solving problems. There is great value in these unexpected benefits and possibilities. In this talk we will visit some such recently uncovered treasures and have fun torturing them mathematically and hacking them though live coding in order to create beautiful visuals.Inigo Quilez grew up as a teenager enjoying mountains, snow, sea and nature, but also programming fractals, graphics algorithms and all sort of visual experiments. At the age of 18, right upon the discovery of the underground community called "the demoscene" and the potential of using code and maths to build beauty, he decided to focus all of his work and time into the creative side of computer graphics. After having finished his degree in Telecom Engineering, and having worked professionally in virtual reality and real-time rendering of massive data sets in Belgium for many years, he now works at Pixar Animation Studios in California doing what he likes the most: inventing techniques and formulas, painting, drawing and creating procedural imagery and animation. In his spare time Inigo continues doing computer graphics, both in and out of the demoscene. One such effort has been the website Shadertoy, of which he is the co-founder.
NVScene 2014 Session: Interactive Simulations (where nobody has to die) (Robert Hodgin) NVScene 2016-04-24 | My work over the last few years has trended towards three main categories: Flocking Simulations, Terrain Engines, and Astronomical Visualizations. Additionally, I strive for real-time so most of my work can be experienced with peripherals like the Oculus Rift VR headset or the LEAP Motion Controller. I will showcase a few of these projects and explain some of the methodology and creative influences that helped shape the end result. I will show no code, but I hope to inspire.Robert is a co-creator of the Cinder C++ framework and was a founding partner of the Barbarian Group. He also worked with Bloom to create the Planetary app which was the first code acquisition by the Smithsonian Cooper-Hewitt National Design Museum.He works primarily in C++, OpenGL, and GLSL. His coding style has been described as "sloppy" and "tightly coupled" but he still manages to create beautiful work if he does say so himself. Which he does. Often.He lives and works in Brooklyn.
NVScene 2014 Session: A Journey Into the Depths of a 4096 Bytes Production NVScene 2016-04-24 | In an era when disk space is measured in terabytes, some people still try to optimize programs for size. 4KB intro developers combine digital artistry and technical ingenuity to bring to life productions full of graphics and music, all wrapped into a program measuring in at only 4 KB or less.In this dynamic presentation, BarZoule and Polaris will discuss the art and the science of creating 4kb intros. The audience will get a one of a kind behind the scenes view as we journey through the creation of the 4kb intro W4K3D, winner of @Party 2012.Each speaker brings their own perspective to the creation process, to give you a true sense of the various aspects of intro conception, design, creation and realization. Not to be missed by people who enjoy unusual technical feats of beauty.Having started making games at the age of 15, Beausoleil quickly learned any new skill set as required. Strong believer in DYI and self-teaching, he's now a game designer during the day, and makes demos at night. Demomaking allows him to play with any tech area he likes. From fitting a drum'n'bass music in a couple of bytes, to 3d modeling or coding software renderer for ASCII output. He also runs the annual Text Mode Demo Competition and the Recursion demoparty in Montréal.Polaris is the founder, organizer and a coder for the Northern Dragons demo-group. Since 2001 the group has created demos, and intros and more for events all over the world. In 2005, Polaris co-founded the web portal “in4k” which remains one of the top go to technical resources for 4k intro development.
NVScene 2014 Session: Rules of Thumb for (slightly) Better Design (Thomas Mann) NVScene 2016-04-24 | Through his experience in the demoscene, education as an architect, and day job as a designer, Pixtur has assembled a basket of easy-to-understand and easy-to-implement rules of thumb for creating better design – with or without programming. He will cover a wide range of topics like ideation, concept, colors, composition, editing and animation – all illustrated with examples from the demoscene.Pixtur has been playing around with code and design for almost three decades (but he feels much younger). As a member of demoscene groups such as Still, Bauknecht, and Haujobb he's won several competitions and awards in a variety of categories. Recently he and two other demosceners founded Framefield, a small Berlin-based agency for interactive realtime graphics.
NVScene 2014 Session: Procedural Content Generation and Shaders (Etienne Caron) NVScene 2016-04-22 | Demosceners are no strangers to Procedural Generation. In the early days computing resources were very limited, and Procedural Generation algorithms provided ways to generate complex and entrancing graphical constructs, going beyond simple disk space or memory limitations.With the mobile revolution upon us, we now all have extremely powerful computers that fit in our pockets. But oddly, we are now faced with new limitations, in the form of bandwith, storage space, etc.Procedural generation allow us to take simple seeds, and with the right algorithm turn them into massive universes to explore.This talk will focus on Procedural Content Generation techniques, and how to use them in concert with OpenGL ES Shaders to maximum effect.Note: This talk will be using the NVidia Shield and Tegra tools suite for it's example code, but could be of interest to anyone new to Procedural Content Generation and Shaders.An active member of the North American demoscene in the 90s, Etienne was a main organizer for the NAID Demoparties (95/96). Now the Android lead developer for PasswordBox.com, Etienne is also the current lead of GDG Montreal-Android. GDGs are independent, Google backed developer groups.
NVScene 2014 Session: A Really Realtime Raytracer (Matt Swoboda) NVScene 2016-04-22 | Realtime renderers find many important visual effects - such as reflections, refractions and global illumination - complicated, slow or impossible because they rely on ray tracing. These effects are necessary to approach the quality of an offline production render.While offline raytracers move to GPU and begin to approach "interactive" performance in the right situation, they are still not truely realtime - coping with ever-changing, moving scenes, lights and cameras, and producing a whole frame at final quality 30 times a second.This talk discusses a GPU raytracer that is focused on realtime applications throughout - the data structures, optimisation for GPU compute, and the tricks and shortcuts used to achieve real time performance and some great visual effects.Matt has a background in graphics programming in both the demoscene and the games industry. He spent 8 years in Sony Computer Entertainment's R&D group researching innovative graphics techniques on games consoles, and worked on every Sony console from Playstation 2 onwards. After moving into the live visuals world, he now works at D3 Technologies and his own production company Run Things. As a part of the legendary demogroup Fairlight he's been responsible for a number of award-winning demoscene productions, and has won more Scene.org awards than anyone else.
NVScene 2014 Session: An Introduction To the Possibilities of VR/AR (Visa Valtteri Pimiä) NVScene 2016-04-22 | VR is finally here despite all the hard years of birthing pains and problems along the way. Now that the hardware is up to the task, the real challenge lies in the VR software experiences. What does this mean for digital artists? How could we build meaningful immersive virtual realities for a single person to experience in the realm of digital art? What about getting rid of that ugly HDMI cable to the PC?This presentation introduces some ideas for interaction and exploration of a VR art piece, and outlines the technological requirements for a believable VR experience in the rendering and audio side of things. The presentation also touches on the latest advancements of AR technology and how it can be harnessed for similar uses.Known in the demoscene as visy, Visa-Valtteri has experimented with demo art since 2001 and he has been interested in the artistic possibilities of computers since laying his eyes on the Commodore 64.Working with Trilobit and Bilotrip, he is best known from demos for 8-bit devices such as Nintendo NES and Atari 2600 and has been homebrewing everything from games to glitchfests on all kinds of imaginable computer and console platforms.Professionally he's worked on game tech and mobile apps for companies like SCEE, Samsung and Remedy among others. He is a passionate gamer and helps run the indie game studio Hyperspace Yard.
NVScene 2014 Session: Real-time Fluid Dynamics (Maciej Matyka) NVScene 2016-04-22 | Note: this recording is of questionable audio and video quality, however: it's the only one we have of this session, therefore we decided to make it available anyway - we hope you enjoy it!Simulation and rendering of the fluid flow at interactive frame rates is a challenging task. It requires algorithmic optimization, compromises on physics and a proper choice of the numerical model. I will discuss these points with focus on two techniques useful in games and demos: animation aerodynamics for simplified Navier-Stokes equations and the Lattice Boltzmann Method. Recent projects based on compute shaders will be presented.Maciej has been a scientist working for many years on the fluid flow through porous media and the fluid flow in computer graphics. He implemented and experimented with many solvers for the Navier-Stokes equations i.e. the marker-and-cell method, the Lattice Boltzmann method, Smoothed Particles and used these techniques in demos: the tree effect in Crush (1st demo at Breakpoint), the river flow in Bremen (3rd intro at Breakpoint) and the main theme in Pord Tuo (3rd demo at Revision).
NVScene 2014 Session: Demo effects on the classic Amiga (Aske Simon Christensen) NVScene 2016-04-22 | Note: this recording is of questionable audio and video quality, however: it's the only one we have of this session, therefore we decided to make it available anyway - we hope you enjoy it!Slides available for download at files.scene.org/view/parties/2014/nvscene14/misc/seminars/nvscene14_demo_effects_on_the_classic_amiga.zipThis talk will take the audience 25 years back in time to the childhood of real-time graphics. We will take a technical dive into the Amiga graphics hardware to discover how a machine of such modest computational power could produce such amazing graphical effects for its time. We will look at several classical demo effects and discuss how they were achieved.Aske Simon Christensen has been coding demo effects on the Amiga since 1992 and on the PC since 2005. He has a strong fascination of size-limited demos and is one of the authors of the Crinkler compression tool, which is widely used in the demoscene for compressing 4-kilobyte intros. Professionally, he has a PhD in computer science and has worked for ARM building the shader compiler for the ARM Mali series of GPUs. He is currently employed in the bioinformatics industry.
NVScene 2015 Session: Creating Interactive Visuals for Large Audiences (Joel Pryde) NVScene 2015-07-05 | This session will cover what Joel has learned from working on interactive visuals for festivals, conferences and public places and some of the challenges of working in these venues. Both for his professional work at Stimulant (http://stimulant.com) as well as his side projects where he has created a number of very large scale interactive pieces for festivals such as Decibel, conferences like CES and various other public venues.This talk would include a quick high level overview of the work I've done and some of the tools and practices that have served me in building these creations and allowing them to react to music, the audience and changes in environment.

NVScene 2015 Session: Android Performance Patterns: Flow (Etienne Caron) NVScene 2015-03-24 | On mobile devices, tactile feedback provides a very close, personal interaction with users. Lack of speed or sluggishness compromises this feedback loop, and multiple UX studies have shown this has a very real impact on users and how they use your software. Fluid feedback can have huge impact on getting your work noticed and adopted by users. A well crafted UI/UX can induce 'flow', or hyperfocus in your users. Something demos usually excel at provoking in viewers. In this session, we'll leverage demoscene know-how to create rich dynamic user interfaces, combining shader rendering tricks with traditional Android UI elements. We'll also learn how to efficiently use the Android platform tools to keep your framerate at a rock-solid 60fps.Recorded live at NVScene 2015.Web: http://nv.scene.orgTwitter: http://twitter.com/nvsceneFacebook: http://facebook.com/nvscene
NVScene 2015 Session: How to Create Content with Signed Distance Functions (Johann Korndörfer) NVScene 2015-03-24 | Good Signed Distance Functions define geometry by providing a semantic description that is very close to the essence of what the shape actually is - but that is almost completely lost when working with polygons or voxels, who solve the problem by throwing big amounts of data at it. Think vector graphics vs. pixels. As a result, SDFs can describe objects in an elegant way that makes variation, animation and last-minute changes trivial. Since building good SDFs is not straightforward, this talk will focus on patterns that help with the modelling process by making it more structured, such as two different families of operators, debugging views, and assorted best practices that have helped us build last year's "the timeless" and other 64k and 4k intros. A very short introduction will show what a Signed Distance Function is (spoiler: a piece of code), what properties it should have and how it is commonly rendered. We will then probably spend most of the time live-coding SDFs and looking at creating geometry using this technique.Recorded live at NVScene 2015.Web: http://nv.scene.orgTwitter: http://twitter.com/nvsceneFacebook: http://facebook.com/nvscene
NVScene 2015 Session: Textmode Is Awesome (Bo Samson) NVScene 2015-03-24 | We'll be defining what a textmode demo is, and why we should care. From there, we'll have a look at what makes one go from good to great, design-wise. From content to colours to graphic style, these tiny choices can have huge impact. We'll also see how your design can be dependent on your pixel-to-character converter. We'll cover the most popular approaches, both in colour mixing and subsampling, along with their forces and drawbacks. If time allows, we'll look at what cool stuff has been or could be done with the extremely low resolution. Come along, we'll have a blast!Recorded live at NVScene 2015.Web: http://nv.scene.orgTwitter: http://twitter.com/nvsceneFacebook: http://facebook.com/nvscene
NVScene 2015 Session: Enough - An Interactive Storybook (Isaac Cohen) NVScene 2015-03-24 | Enough is an exploration in interactive storytelling. Because of the power of real time graphics, we are entering an era of redefining what fiction means. Although many times the progression of this art finds itself in the realm of RPGs and FPSs , Enough tries to reexamine what a 'Picture Book' could mean in the time of modern GPUs.Recorded live at NVScene 2015.Web: http://nv.scene.orgTwitter: http://twitter.com/nvsceneFacebook: http://facebook.com/nvscene
NVScene 2015 Session: Graphics Programming Through the Ages (Michael Dille, Keith Bare) NVScene 2015-03-24 | Many new computers over the years have generated great excitement with ever more powerful graphical abilities. To facilitate this, machine designers developed a variety of creative (if largely now arcane) programming interfaces that allowed software authors to squeeze impressive displays from scant computational resources, an art perfected by the demoscene. This talk will focus on a few famous case studies such as the Commodore 64, the Amiga, and early PCs while exploring how each respective architecture influenced the style and appearance of demos on that platform. This chronology of hardware history provides the context to then appreciate the evolution of demos from machine-specific skills demonstrations to immersive graphical simulations, reaching the modern emphasis on aesthetics and production while offering a nod to today's "low-fi" demoscene that retains a focus on pure programming challenge.Recorded live at NVScene 2015.Web: http://nv.scene.orgTwitter: http://twitter.com/nvsceneFacebook: http://facebook.com/nvscene
NVScene 2015 Session: Real Virtuality - Adventures in WebVR (Antti Jädertpolm) NVScene 2015-03-24 | In this session, we will go over the brief history of online VR (WebVR) and what the future holds for the medium. We will showcase different frameworks and tools that are currently available and being used for WebVR and discuss how both businesses and art can benefit from it. Antti will demonstrate how he has used VR to create unique demoscene related effects through his own visual programming interface and share his experiences with VR in general.Recorded live at NVScene 2015.Web: http://nv.scene.orgTwitter: http://twitter.com/nvsceneFacebook: http://facebook.com/nvscene

NVScene 2015 Session: Thinking Outside the Cartridge: Modern Ideas on Archaic Devices (Jake Taylor) NVScene 2015-03-24 | Ever wanted to make something that looks and sounds awesome with a gaming console you've played on your entire life? Ever wanted to build a proper, modern toolset to do so and experiment with functional programming at the same time? Then this talk is for you! We'll take a look at two recent Super Nintendo demos, and, in particular, the ideas and methodologies applied when making them. First, we'll go over some of the details of the SNES' quirky hardware and the usual methods of making it tick. Building from there, we'll look at how most of this can be reduced to "simple" data processing, and how modern development techniques can be applied to make this simpler and more interesting. All in all, this talk aims to show how applicable modern programming practices can be to unexpected problem domains, and how inspiring it can be to work with creative, out-of-the-box solutions. After all, a little ancient console dev never hurt anyone, right?Recorded live at NVScene 2015.Web: http://nv.scene.orgTwitter: http://twitter.com/nvsceneFacebook: http://facebook.com/nvscene
NVScene 2015 Session: Tips For Efficient and Impressive Animations (Alexander Lehmann) NVScene 2015-03-24 | Creating animated short films, music videos and demos is an extremely complex process. Between a concept and the final release many fields of filmmaking and design needs to be mastered and applied. In this session Alexander will show and explain the workflow which he developed to create impressive animations on a tight budget of both time and funds. We will look at fun and time efficient processes and techniques that allows you to become a self-employed "one man 3D army". Alexander will also cover how he started his animation studio and how the demoscene has always played a role in it.Recorded live at NVScene 2015.Web: http://nv.scene.orgTwitter: http://twitter.com/nvsceneFacebook: http://facebook.com/nvscene
