Back To Basics: C++ Containers javidx9 2021-04-05 | Containers provided by the standard library in C++ have almost become as essential as the language keywords themselves. Storing data in the correct way will make you a fluid and stronger programmer, as you can let the containers do the hard work for you. In this video I take a really brief look at the main containers std::array, std::vector, std::list, std::deque, std::set, std::unordered_set, std::map, std::unordered_map.CppCast: https://cppcast.com/one-lone-coder/Patreon: https://www.patreon.com/javidx9YouTube: https://www.youtube.com/javidx9 https://www.youtube.com/javidx9extraDiscord: https://discord.gg/WhwHUMVTwitter: https://www.twitter.com/javidx9Twitch: https://www.twitch.tv/javidx9GitHub: https://www.github.com/onelonecoderHomepage: https://www.onelonecoder.com

Essential Mathematics For Aspiring Game Developers javidx9 2020-06-13 | This video outlines what I believe are some of the core principles you need to understand to make dynamic computer games, covering vectors, angles and motion. I've tried to present it in such a way that highlights the relationships between these principles, so you can identify when to use one or the other, or combinations of them. It is by no means an exhaustive list, but gives the beginner/aspiring games programmer a place to start.Patreon: https://www.patreon.com/javidx9YouTube: https://www.youtube.com/javidx9 https://www.youtube.com/javidx9extraDiscord: https://discord.gg/WhwHUMVTwitter: https://www.twitter.com/javidx9Twitch: https://www.twitch.tv/javidx9GitHub: https://www.github.com/onelonecoderHomepage: https://www.onelonecoder.com
Intrinsic Functions - Vector Processing Extensions javidx9 2020-05-30 | Ooof! Well you guys asked for it, and it's up there in complexity for this channel! XD In this video I demonstrate how CPU Extensions can be used in your C++ programs via Compiler Intrinsic Functions to perform SIMD parallel operations. First I demonstrate how these extensions look and feel, then I implement the Mandelbrot Fractal generation code form my previous video.Source: https://github.com/OneLoneCoder/Javidx9/blob/master/PixelGameEngine/SmallerProjects/OneLoneCoder_VIDEO_IntrinsicFunctions.cppPatreon: https://www.patreon.com/javidx9YouTube: https://www.youtube.com/javidx9 https://www.youtube.com/javidx9extraDiscord: https://discord.gg/WhwHUMVTwitter: https://www.twitter.com/javidx9Twitch: https://www.twitch.tv/javidx9GitHub: https://www.github.com/onelonecoderHomepage: https://www.onelonecoder.com
Brute Force Processing javidx9 2020-05-16 | In this video, I examine a sequence of strategies to try and improve the rendering speed of a Mandelbrot Fractal. Starting off with naive assumptions, I explore optimising the algorithm, then the use of vector co-processing, and finally threads and thread-pools in order to squeeze as much out of my CPU as I can.Source: https://github.com/OneLoneCoder/Javidx9/blob/master/PixelGameEngine/SmallerProjects/OneLoneCoder_PGE_Mandelbrot.cppPatreon: https://www.patreon.com/javidx9YouTube: https://www.youtube.com/javidx9 https://www.youtube.com/javidx9extraDiscord: https://discord.gg/WhwHUMVTwitter: https://www.twitter.com/javidx9Twitch: https://www.twitch.tv/javidx9GitHub: https://www.github.com/onelonecoderHomepage: https://www.onelonecoder.com
Dungeon Warping via Orthographic Projections javidx9 2020-04-25 | In this video I use Orthographic Projection to simplify the structure of a 3D world rendered with a 2D aesthetic.
