Yes. For example, O3D lets you specify a light source and a bump map for objects whereas this API would not. Also O3D gives you access to hardware accelerated pixel shaders. > And you're also saying that it isn't the intention of WebKit's > implementation (or Apple's Working Draft) of SVG Transforms (as > per http://www.w3.org/TR/SVG-Transforms/ ) to allow for the construction and > styling of full scenes and models like those in O3D? I can't speak for Apple, but that would be quite surprising. If you're interested in this topic, you might be interested in reading about Cg and the O3D shading language: http://developer.nvidia.com/page/cg_main.html http://code.google.com/apis/o3d/docs/shadinglanguage.html > The draft has a > combination of CSS transitions, CSS Animations and CSS 3D to plug into SVG, > so it would seem like any composition using SVG Transforms could accomplish > mostly with CSS what O3D accomplishes with JavaScript (unless I'm not > reading it correctly). There's a lot more to 3D rendering than transitions, animations, and transforms. In particular, 3D is largely about framing your drawing in a way that your graphics hardware can be blazingly fast. That's way most modern 3D drawing APIs use something akin to glDrawElements: http://code.google.com/apis/o3d/docs/reference/classo3d_1_1_draw_element.html This API is usually the fastest possible way to send geometry information from main memory to the GPU.
