Interactive KD-Tree GPU Raytracing. We have implemented a raytracer in both CTM and DirectX (through brook). On modern architectures the raytracer gets between 10 and 20 million rays per second on 300,000 polygon scenes.... and …

Over the past few years, the powerful computation rates and high memory bandwidth of GPUs have attracted efforts to run raytracing on GPUs. Our work extends Foley et al.'s GPU k-d tree research. We port their kd-restart algorithm from multi-pass, using CPU load balancing, to single pass, using current GPUs' branching and looping abilities. We introduce three optimizations: a …

scenes and determines that the kd-tree is the best general-purpose acceleration structure for CPU raytracers. It would seem natural, therefore, to try to use a kd-tree to accelerate GPU raytracing. As we will describe in section 2 though, the standard algorithm for kd-tree traversal relies on a per-ray dynamic stack. Ernst et al. [EVG04] demonstrate that

Remove the skybox sampling code if you haven’t already, and add the following lines to trace the ray and shade the hit: // Trace and shade RayHit hit = Trace (ray); float3 result = Shade (ray, hit); Result [id.xy] = float4 (result, 1); // Trace and shade. RayHit hit = Trace(ray); float3 result = Shade(ray, hit);

Very Fast Ray Traversal Even for scenes with 100K+ triangles, our ray tracer can achieve a throughput of 275+ Mrays/s on GTX 680 for primary ray using a single GPU. And we can render a 1000x1000 picture of the scene with ambient occlusion at 60+ FPS, while its CPU counterpart stays with 0.30 FPS. Very Fast Parallel BVH Tree Construction

S. Popov, J. Günther, H.-P. Seidel, and P. Slusallek / Stackless KD-Tree Traversal for High Performance GPU Ray Tracing Figure 2: A kd-tree with “ropes”. Ropes link each leaf node of the kd-tree via its six faces directly to the corresponding adjacent node of that face or to the smallest node enclosing all adjacent nodes if there are multiple. 3.

The intersection point is around 1.8k. Past this point using a kdtree starts to have an advantage. The higher the complexity, the more useful the tree becomes which is expected.
