We propose new approaches to ray tracing that greatly reduce the required number of operations while strictly preserving the geometrical correctness of the solution. A hierarchical "beam" structure serves as a proxy for a collection of rays. It is tested against a kd-tree representing the overall scene in order to discard from consideration the sub-set of(More)
We present a highly parallel, linearly scalable technique of kd-tree construction for ray tracing of dynamic geometry. We use conventional kd-tree compatible with the high performing algorithms such as MLRTA or frustum tracing. Proposed technique offers exceptional construction speed maintaining reasonable kd-tree quality for rendering stage. The algorithm(More)
Game physics is at the heart of any modern game engine which employs the laws of physics to simulate life-like movement and interaction between objects, such as rigid and deformable bodies, cloth, and water. Game physics applications are very compute and memory intensive. The ever growing quest for a high degree of realism requires more complex physics(More)
Most modern games use deferred shading, in which shading is performed only for visible pixels, allowing greater artistic freedom in scene composing and lighting. However, traditional antialiasing techniques, such as super-sampling and multi-sampling, are not well-suited for deferred shading pipeline, since all subsamples have to be explicitly written to(More)
