change view

[tracey]

Hi,
I have a question about changing view position so the viewer can see the sorrounding objects also include the viewer is in motion ( for example: viewer is moving around a circle).
I have my program using:
gluPerspective( 60.0f, aspect, nearClip, farClip );
Should I just add some variables into this function to achive above purpose.
Could someone help me? Thank you.

glPerspective or ortho set's your viewing volume and not location.

To set the scene view do it in model view with gluLookAt or rotate/translate commands, then draw your scene
