Abstract
Radiosity computation on scenes including objects with a complex geometry, or with a large number of faces and meshes with very different sizes, is very complex. We present a new method (based on the Photon Maps method [7]) where density estimation on the tangent plane at each surface point is performed for irradiance computation by using photon paths (line segments traveled by a ray) instead of photon impacts. Therefore we improve the results for scenes containing small objects which receive only a few impacts. Also, geometry is completely decoupled from radiosity computation.
