Moving the Camera We can move the camera to any desired position by a sequence of rotations and translations Example: side view Rotate the camera Move it away from origin Model-view matrix C = TR
Moving the Camera We must be careful for two reasons: First, we usually want to define the camera before we position the objects in the scene. Second, transformations on the camera may appear to be backward from what we might expect. glMatrixMode(GL_MODELVIEW); glLoadIdentity( ); glTranslatef(0.0, 0.0, -d); glRotatef(-90.0, 0.0, 1.0, 0.0)
