Find front face of a cube
May 31st, 2008, 7:18am  
Hello math wizards. I'm trying to find a way to determine what face of a cube is currently pointed towards the positive z axis of a 3D space.

I have created the cube at 0,0,0 and I am rotating it around the x, y and z axises incrementally. Something like:

setYRotation( ++myY );
setXRotation( ++myX );
setZRotation( ++myZ );
box( 50 );

I'd like to know which face is pointing towards the camera (given that the camera is fixed at 0,0,200) at any point in time. My mind is tied in knots trying to figure this out.

Thanks in advance for your help
