The Khronos Group is keeping busy at Siggraph. After announcing its new OpenGL 3.2 specification and talking to us about OpenCL, the organization has shed more light on the "Accelerated 3D on Web" working group, which it first teased in March.
Support for OpenGL or OpenGL ES means WebGL should work on both conventional PCs and handheld devices with OpenGL ES support—like, say, an iPhone 3G S. Khronos President Neil Trevett told us he didn't want to speak for Apple's product plans, but the spec would nevertheless make an iPhone implementation possible "if [Apple] chose to do it."
Right now, the WebGL working group includes AMD, Ericsson, Google, Mozilla, Nvidia, and Opera. We may therefore see native implementations in at least the Chrome, Firefox, and Opera web browsers. Microsoft isn't a member of Khronos, but Trevett told us Khronos will "encourage" the company to adopt HTML 5 and WebGL in Internet Explorer.
