i found these extensions in the glew source, but could not find any documentation for them (yet?) on the net. does anyone know if they're alrady supported and what they're for? i guess they're supposed to send tangent and binormal attribute arrays to a glsl vertex program? edit: k seems to be part of this one: http://icps.u-strasbg.fr/~marchesin/perso/extensions/EXT/coordinate_frame.html

Interesting, I had never heard of this extension before. Actually it's easy to set up Vertex Attrib arrays with your custom data so it's not that much of an issue I guess.

Anyway, here is nmore info on this extension, and the first line in bold should interest you [wink].

/edit: The same info was there in the apge you linked to as well.

well that's what i'm having problems with atm, that's why found this extension :) i just tried to use it, and it's really not implemented yet, at least not in the ati drivers.

I reckon solving the Vertex attribute problem should be easier than finding an implementation of an extension whose specs say "Do not implement" in bold at the top [wink].

Cheers!

Judging by the date on the extension it was SGI's method of passing more per-vertex data to the fixed function pipeline, however with the advent programable hardware and generic vertex streams it would leave such an extension redundant at best.
