Particle Tracing Methods in Photorealistic Image Synthesis Rázsó István Márk rezso@inf.bme.hu Department of Control Engineering and Information Technology Technical University of Budapest Budapest, Hungary

    We currently implemented a particle tracer and an inportance sampler. The importance sampler can generate directions using only the BRDF of the surface or using the data provided by the particle tracer. The implementation was easy using our library we are developing.
These scenes are the test scenes for our library. There is an empty office room, and another one with books on the table and a mirror on the wall. We have a box with one lightsource on the ceiling and one behind the camera.

On this picture there is the box scene rendered with different number of samples taken at each pixel. The number of samples from left to right are: 1, 2, 4, 8, 16, 32, 64 and 128.
