Beginners Guide to WebGL From Scratch with Scripts
I have prepared bundle of very basic tutorials on WebGL to draw points, line,line strip, triangle, triangle strip , rectangle , circle and changing the color of the object drawn on the canvas.
What is WebGL ?
The principles are generic: WebGL is based on OpenGLES 2.0 (OpenGL for Embedded Systems – which is a subset of the OpenGL 2.0 computer graphics rendering application programming interface (API) for rendering 2D and 3D computer graphics).
Why WebGL ?
Rendering 3D object directly on the web browser.
The tutorials prepared here is tested on Windows 7 with Chrome Version 41.0.2272.118 m.
