FPS type view

This has been discussed recently in math and physics, so you might look through the last couple pages or so of threads there. In short, gluLookAt() isn't a particularly good choice for an FPS-style camera. All you really need is two angles (yaw and pitch), and a position vector. You then set up your view matrix like this:

glMatrixMode(GL_MODELVIEW);glLoadIdentity();glRotatef(-pitch, 1, 0, 0); // Or whatever axis is to the side for youglRotatef(-yaw, 0, 1, 0); // Or whatever axis is up for youglTranslatef(-pos.x, -pos.y, -pos.z);

You can calculate your forward and side movement vectors using the sine and cosine of your yaw angle. If you need the forward aim vector, you can query the modelview matrix, or construct it yourself using trig.

Thanks. I will look into the physics section then.
