WebGL (short for Web Graphics Library) is a JavaScript API for rendering interactive 2D and 3D graphics within any compatible web browser without the use of plug-ins. [2] WebGL is fully integrated with other web standards, allowing GPU -accelerated usage of physics, image processing, and effects in the HTML canvas.
WebGL 基础概念. WebGL经常被当成3D API，人们总想“我可以使用WebGL和 一些神奇的东西 做出炫酷的3D作品”。. 事实上WebGL仅仅是一个光栅化引擎，它可以根据你的代码绘制出点，线和三角形。. 想要利用WebGL完成更复杂任务，取决于你能否提供合适的代码，组合使用 ...
Feb 23, 2017 · WebGL enables web content to use an API based on OpenGL ES 2.0 to perform 3D rendering in an HTML canvas in browsers that support it without the use of plug-ins. WebGL programs consist of control code written in JavaScript and special effects code (shader code) that is executed on a computer's Graphics Processing Unit (GPU).
Feb 9, 2012 · WebGL Fundamentals. WebGL makes it possible to display amazing realtime 3D graphics in your browser but what many people don't know is that WebGL is actually a 2D API, not a 3D API. Let me explain. WebGL only cares about 2 things. Clipspace coordinates in 2D and colors. Your job as a programmer using WebGL is to provide WebGL with those 2 things.
WebGL (Web Graphics Library) is often thought of as a 3D API. People think "I'll use WebGL and magic I'll get cool 3d". In reality WebGL is just a rasterization engine. It draws points, lines, and triangles based on code you supply. Getting WebGL to do anything else is up to you to provide code to use points, lines, and triangles to accomplish ...
Dec 16, 2015 · WebGL (Web Graphics Library) is a JavaScript API for rendering interactive 3D computer graphics and 2D graphics within any compatible web browser without the use of plug-ins.
