you can use the method gluLookAt().


void gluLookAt(camera_x,camera_y,camera_z, centerx, centery, centerz, upvector_x, upvector_y, upvectorz);


A usage would be

void Render()
{
gluLookAt(0.0f, 3.0f,-5.0f,
0.0f, 0.0f, 0.0f,
0.0f, 1.0f, 0.0f);

auxSolidCube(2.0f);

// This code should position the camera at [0, 3, -5], looking at
// the center of the world [0, 0, 0], with the up direction along the
// positive y axis. Then draw a solid cube at the center.
}
