The present invention relates to a rendering technique based on a ray tracing, a method of processing global illumination, includes (a) performing a ray tracing on a certain pixel from a given light source to generate a direct light shading, (b) determining at least one indirect light source on the certain pixel for an indirect light shading and (c) performing a ray tracing on the certain pixel from the at least one indirect light source to generate an indirect light shading. |
