WebThe Intersection Program When optixTrace is called, the specified ray traverses the acceleration data structure provided. On NVIDIA RTX GPUs, this can be executed on special purpose hardware to allow exceptionally efficient traversal of the acceleration structure. WebThe OptiX engine is composed of two symbiotic parts: 1) a host-based API that defines ray-tracing based data structures, and 2) a CUDA C-based programming system that can produce new rays, intersect rays with surfaces, and respond to those intersections. Together, these two pieces provide low-level support for “raw ray tracing”. greece town court phone number
