ARS Technica is reporting on Apple's development of 2D and 3D graphics for the iPhone:
The WebKit team added CSS Transforms to nightly builds of WebKit back in October 2007, transforms that included scaling, rotation, skewing, and translation in 2D space. As the specification matured, 3D and animation capabilities were added. Eventually, the 3D transforms were broken out into a specification of their own.
The hardware-accelerated CAD-friendly routines are enabled on the Mobile Safari Web browser running on the iPhone and iPod Touch only.
