I'm trying to do something pretty standard: rotate a 3D object around a point, using an axis defined by a unit vector, and an angle defined by a float. It works fine 90% of the time, but in certain positions, the matrix gets transformed to a bunch of huge negative values, like an overflow occured. Has anyone experienced a similar problem? - Evan

Can you post some code? Info about what math library or API you're using would also be helpful.

Hmm, how do I paste source code into one of those scrollable windows with syntax coloring? (I'm new here.)

Okay I found the error. I had accidentally put a transformation from local space to world space inside a loop that should have been outside the loop. (Something to look for if your matrices ever blow up :D )

Also, I'm still trying to figure out how to paste source code with syntax coloring. Any help?
