Viewing APIs We can take a different approach to positioning the camera – We describe the camera’s position and orientation in the world frame It’s desired location is centered at the view-reference point (VRP) It’s orientation is specified with the viewplane normal (VPN) and the view-up vector (VUP)
gluLookAt GL uses a more direct method, fortunately. gluLookAt(eyex, eyey, eyez, atx, aty, atz, upx, upy, upz);
