Interessante articolo su hacks.mozilla.org che introduce e chiarisce alcuni concetti fondamentali dietro le WebGL.
What is WebGL?
WebGL is a Web API that allows low-level graphics programming. “Low-level” means that WebGL commands are expressed in terms that map relatively directly to how a GPU (graphics processing unit, i.e. hardware) actually works. That means that WebGL allows you to really tap into the feature set and power of graphics hardware. What native games do with OpenGL or Direct3D, you can probably do with WebGL too.
