The matrix functions in the above canvas would be really useful if they could call vecLib instead of doing them all with plain javascript. that way you'd get a lot more speed and people could write Quake with canvas. See also http://www.abrahamjoffe.com.au/ben/canvascape/textures.htm It would be even better if the JavaScript interpreter could recognise where code could be pushed through the vector engine (PPC or Intel) and do so without the author having to edit the code. (i.e. auto-vectorising interpreter)
I'm not sure what this bug is asking for. Please provide a specific proposal of functions/datatypes you are looking for, and re-open.
*I* am not looking for any, i don't have javascript turned on anyway. but people are doing matrix operations in unoptimised javascript on the integer unit of the CPU. providing some built‐in functions that map to C functions from apple's veclib frameworks can only help speed up stuff.
