Is it not possible to transfer all canvas' 2D feature into WebGL appearance to make a 3D context? Everything the same except that when setting the getCentext, you pass 3D instead of 2D. This will make for a more friendly yet familiar tool to use. Utilizing WebGL with set features as 2D getContext. I believe this proposal is worth looking at and giving thought to; all one would have to do is define the API of 2D context in WebGL to have a easy 3D context, ensnare if I it's limited, or won't showcase the full capability that is WebGL, it'll allow those to take a step toward WebGL by introducing it in a familiar API.
var ctx = canvas.getContext("2D"); Var ctx = canvas.getContext("3D"); By predefining all the feature of 2D context into WebGL to render them in 3D context. By doing so, giving a friendly to use, familiar API to work with, instead of learning a library.(some of us believe in non library programming). Please take interest, or at least thought of mind of this ideal... Seeing that the canvas feature are few, I can't see how hard this would be for an evangelist to complete in an hour or so.
