How much overhead is there really for garbage collection, is it as high as so many people say it is?

Garbage Collection is often cited as a major source of performance problems in JavaScript. In this vdeo, we explore garbage collection a bit, and try to understand when and how the overhead is high and when it isn't.

$Fog, Basic Fog, and Better Fog (Three.js Tutorial) In this project, I’ll show you how to use fog, and then i’ll show you how to improve it to get something a bit more like Unity’s. Follow me on: Patreon: https://www.patreon.com/simondevyt Twitter: https://twitter.com/iced_coffee_dev Github: https://github.com/simondevyoutube/ Well be looking at fog support in three.js, and JavaScript. This tutorial covers the API in Three.js, what modes of fog it supports, and how to extend this by hacking on the shader internals to inject our own code. From there, we can look at Unitys height for for inspiration and add in Wenzels height fog, with some animated perlin noise using fractal brownian motion for some extra detail. This tutorial uses three.js, which is a library in JavaScript for cross-browser 3d graphics using webgl. It makes high level functionality and advanced graphics available on the web. In the video, we cover: * Linear and Exponential Fog * WebGL and glFog * Three.js APIs, Fog and FogExp * Wenzels Height Fog * Domain warping using fractal brownian motion Links: https://developer.amd.com/wordpress/media/2012/10/Wenzel-Real-time_Atmospheric_Effects_in_Games.pdf https://www.iquilezles.org/www/articles/warp/warp.htm https://www.iquilezles.org/www/articles/fog/fog.htm https://www.shadertoy.com/view/4s23zz https://www.shadertoy.com/view/lsl3RH https://www.khronos.org/registry/OpenGL/specs/gl/glspec10.pdf https://www.khronos.org/opengl/wiki/Fixed_Function_Pipeline https://docs.unity3d.com/540/Documentation/Manual/script-GlobalFog.html https://threejs.org/docs/#api/en/scenes/Fog https://threejs.org/docs/#api/en/scenes/FogExp2$
