What is the role of ray tracing in visible surface detection? Explain How scan line algorithm is used for back face detection. [5]
--- Ray tracing is an image-space method for visible surface detection. The basic idea is to trace the path of light rays from the viewer's eye (or camera) through each pixel on the projection plane into the scene. 1. For each pixel on the screen, a ray is cast from the eye position through that ...
