摘要：

The objective of this paper is to adapt photon mapping for real-time simulation of caustics. High-performance algorithm adapted for the GPU and implemented on the basis of cross-platform OpenGL and OpenCL APIs is proposed. For effective rendering of caustics and generation of photon map OpenGL shaders are used. Voxel acceleration structure constructed directly on the GPU by means of OpenCL provides fast access to photon map. Performance estimation for different equipment is given.
