Ok, after comparing the API's more closely, OpenCL does follow an object model much more closely than OpenGL. Even though it's a C API, every call that is not "static" contains the object being operated on. So that makes the WebCL API a good reflection of OpenCL.

The only question is how WebCL and WebGL interact. OpenCL has an API for this purpose, but I don't see that represented in WebCL. Is that API coming, or did I miss seeing it in the current API?
