Hi,

I have a rotation matrix (combined for the 3 axes) that works ok in OpenGL, but I'm having trouble converting it for Direct3D. Which steps exactly should I follow to get it working in Direct3D?

It still doesn't work, I think I need more specific help 8-)

I wrote my application completely for Direct3D, but I'm getting this single rotation matrix from a static library that uses OpenGL's matrices. I don't have quaternions or anything else, I just have this single 4x4 rotation matrix, that represent a combined rotation in all 3 axes for a right handed system.

First I transpose the matrix, then I think I need to negate something but I don't know what or how.

Thanks for any help.

Juan
