This site has a lot of nice, basic lessons on programming computer graphics (particularly on ray tracing for offline rendering). There's a newer version PBRT, this may be a good stepping stone. Damn, this is pretty on par with the ArcSynthesis ... WebFigure 2: to compute direct lighting, we just need to cast a shadow ray from P to the light source. If the ray is blocked by an object on its way to the light, then P is in shadow. Figure 3: to compute indirect lighting, we need to spawn secondary rays from P and check if these rays intersect other surfaces in the scene.
