Abstract

In this paper, we discuss different approaches which may be used to solve the caustic illumination problem including the approximation of the light wavefront method, the backward and forward photon mappings, and propose the method for the effective calculation of the caustic illumination maps to be integrated into a common DirectX rendering pipeline. The proposed method is based on the photon mapping method and adds additional rendering pipeline steps for calculating the visibility maps for forward and backward caustics and then merging them to form the caustic illumination map of the whole scene. The proposed method was implemented, tested, and compared with the ground truth result acquired with realistic rendering software. The test results along with rendered images are presented.
