Ray tracing of dynamic scenes
In the last decade ray tracing performance reached interactive frame rates for nontrivial scenes, which roused the desire to also ray trace dynamic scenes. Changing the geometry of a scene, however, invalidates the precomputed auxiliary data-structures needed to accelerate ray tracing. In this thesis we review and discuss several approaches to deal with the challenge of ray tracing dynamic scen...
متن کاملGPU-based Ray Tracing of Dynamic Scenes
This paper presents the design and implementation of a GPU-based ray tracing system for dynamic scenes consisting of a set of individual, non-deformable objects. The triangles of each object are organized in a separate Kd-tree. A bounding volume hierarchy (BVH) is built on top of these Kd-trees. The BVH is updated and uploaded into GPU memory on a frame-by-frame basis, whereas the Kd-trees are ...
متن کاملHighly Parallel Fast KD-tree Construction for Interactive Ray Tracing of Dynamic Scenes
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 builds a kd-tree from scratch each fra...
متن کاملRay Tracing Animated Scenes using Motion Decomposition
Though ray tracing has recently become interactive, its high precomputation time for building spatial indices usually limits its applications to walkthroughs of static scenes. This is a major limitation, as most applications demand support for dynamically animated models. In this paper, we present a new approach to ray trace a special but important class of dynamic scenes, namely models whose c...
متن کاملRendering Large Scenes Using Parallel Ray Tracing
Ray tracing is a powerful technique to generate realistic images of 3D scenes. However, the rendering of complex scenes may easily exceed the processing and memory capabilities of a single workstation. Distributed processing offers a solution if the algorithm can be parallelised in an efficient way. In this paper a hybrid scheduling approach is presented that combines demand driven and data par...
