Invert Matrix

Recommended Posts

Hey All! I need to invert my model-view matrix. At the moment the only call that I am using to modify the matrix is a call to gluLookAt(). I was wondering if anyone had some code, or new where I could find some code that would easily do this for me? Thanks Danielle

I assume you already have figured out how to *get* the matrix in question. Given the formula for matrix inversion, it should not be too hard to translate into code. Hint: write functions for 2x2 determinant, etc. first so that you don't go insane by trying to expand everything in a single formula. Also observe the patterns in the formula. (And follow the links on that page... lots of fun stuff to learn [smile])
