In recent years, there has been a renewed interest in real-time ray tracing for interactive applications. This is due to many factors: firstly, processor speed has continued to rise at exponential rates as predicted by Moore’s Law and is approaching the raw computational power needed for interactive ray tracing. Secondly, ray tracing algorithms can be highly parallelized on shared memory and distributed memory systems. Therefore, the current hardware trend towards desktop systems with multi-core CPUs and programmable GPUs can be used to accelerate ray tracing. Finally, recent algorithmic improvements that exploit ray coherence can achieve a significant improvement in rendering time.

We have active research projects in the area of interactive ray tracing dealing with problems such as ray tracing massive datasets and deformable models.
