Realistic viewing of perspective images requires placing the viewer at the correct location. In this paper, we present a technique for determining the correct viewing location for perspective images of 3D scenes. The technique is based on the determination of three vanishing points in mutually orthogonal directions. We also use this technique to devise a simple method for manually drawing images of rectangular prisms in correct perspective with respect to a viewpoint.
