My recent tutorials have been looking at putting 3D models into web pages.
What is Webgl? it is a standard supported by Firefox, Chrome and Safari web browsers that interfaces to the user’s graphics card to give hardware accelerated 3D.
Is Webgl relevant to Blender? Webgl is just one technology enabling 3D on the web (Flash being another) but as these technologies become better supported and mature there will be more and more 3D content. Blender is a Digital Content Creation (DCC) tool and is ideal for creating the 3D models, animations and games to go onto the web.
It is early days yet but Webgl and other technologies are well worth watching.
