transpose

[eirikhm]

mat1= transpose(mat2);
compiles on my fx5600 / 57.10 and runs

does this run on ATI as well, or is it just some stuff NV threw in?

[Corrail]

This function is NOT included by the GLSL specification v1.051 so this is a NV-only function. I didn't tried it but I think it won't run on ATI hardware.

In the case you don't need it for 'special' purposes, remember that:

transpose(M)*v = v*M

Note that being 'strict' about notation, in the first case v is a column vector, and in the second case is a row vector.

Hope this helps.

got it working long time ago, just wanted to know
