RENDERING METHOD FOR INDIRECT ILLUMINATION EFFECT

摘要

PURPOSE: A rendering method for indirect illumination effect is provided to maximize physical accuracy compared with calculation time by minimizing an approximate calculation part in consideration of all paths of light corresponding to an indirect illumination part. CONSTITUTION: Visual information is generated through a visibility test about all pixels of a scene(S210). A general photon map and a non-diffuse photon map are respectively generated(S220). Simplified mesh information is generated(S230). An irradiance map of texture form is generated(S240). Through the irradiance map, the effect of a diffuse reflection irradiance is repetitively calculated about all pixels(S250). The effect of non-diffuse reflection irradiance is calculated(S270).
