3D math problem: world to object origin

Phunk(logged out) · Post by **Phunk(logged out)** » Wed Jan 14, 2004 2:58 pm

I can succesfully recreate an FPS cam, but when I try to create a space cam(like the one from [DX/x]=hunt3r) I get as far as him, and then I get stuck: a cam that only works in the world Z origin, When I turn 90 degrees, I have a cam that does a roll instead of pitch. I cant translate the cam origin to anything other than the world origin. How does one do this? I could not find a suitible matrix function for this, an jus adding the new rotation to the current position does not work either. Please help!

simple vector math:

(vector or pos3d)position += (vector)direction.normalized() * (float)speed ;
