WebThe matrix transform that is required in the case of perspective projection (essentially the world-to-camera matrix) is required in exactly the same way when raytracing. However, with perspective projection, you're only transforming the corner points, whereas with raytracing, you're transforming all the points in the image. Martin B 23010. WebRay Tracer.
