What it is
A 40-minute tutorial from Indigo Code, part of a from-scratch WebGL series that avoids libraries like Three.js. It explains how 3D scenes are projected onto a 2D screen and walks through building a rotating 3D cube with the glMatrix math library.

i am new to programming and i want to rotate the 3d cube along x axis using css. I have added the cube and below is the html and css to it. could someone let me know how to add the animation. below is the code, <div id="wrapper"> <div class="cube"> <!--Front--> <div></div> <!--Back--> <div></div> <!--Left--> <div></div> <!--Right--> <div></div> <!--Top--> <div></div> <!--Bottom--> <div></div> </div> </div> #wrapper{ width:300px; height:300px; perspective:700px; -webkit-perspective:700px; margin:100px auto; } .cube{ position:relative; width:150px; height:150px; transform-style:preserve-3d; transform:rotateY(35deg) rotatex(-38deg); } .cube div{ position:absolute; width:150px; height:150px; bac

I'm learning webgl. I'm fallowing a tutorial [this video] on youtube. My issue is the traingle I'm rendering to the canvas is streched out. [LINK] on a wider canvas. [LINK] on a more square canvas. (These are the same triangles.) Is that supposed to happen and how can I fix it.

So I'm learning WebGL for the first time, and I'm having difficulty understanding WebGL colors. My concern is that I have seen 2 formats or conventions for writing RGBA color data (or vectors if that is what they are called? - regarding shaders) Mozilla uses color on a scale of 0 to 255: Here is an example [LINK] However, I have seen other cases where developers (like this [this video] ) use color on a scale of 0 to 1.0, Is this a preference? Is it mandatory what convention you use per situation? If it is preference and not mandate, can I mix and match the two? Do browsers have a preference? For example in regards to mixing, is [1.0, 255, 1.0, 255] fully opaque white?
