In contrast, the kd-tree has gained widespread use in CPU-based raytracers and is regarded as the best general-purpose acceleration structure. We demonstrate two kd-tree traversal algorithms suitable for GPU implementation and integrate them into a streaming raytracer. We show that for scenes ...
This provides a real-time kd-tree algorithm on a GPU, with kd-trees having comparable quality to those constructed by off-line CPU algorithms, but in a manner that is significantly faster than well-optimized single-core CPU algorithms, yet competitive with multi-core CPU algorithms. The algorit...

Current GPU computational power enables the execution of complex and parallel algorithms, such as ray tracing techniques supported by kD-trees for 3D scene rendering in real time. This work describes in detail the study and implementation of eight different kD-tree traversal algorithms using the ...
three components of ray-tracing,i.e.,KD-Tree construction,scene traversal and shading,are performed on GPU,which are scheduled by CPU.Thus GPU computing ability is exploited thoroughly and data transmission overhead is reduced efficiently.By designing algorithms of parallel partitions and SAH,...
