I want to make the camera moving along a circular path around the zero point (0,0,0). So to calculate the position for the camera I use cos(deg) for the x movement and sin(deg) for the z movement in order to move along the path. To obtain the zero point centered on the screen I just calculate deg + 180. When you change your …
