Implementing Stochastic Levels of Detail with Microsoft DirectX Raytracing

Originally published at: https://developer.nvidia.com/blog/implementing-stochastic-lod-with-microsoft-dxr/

Level-of-detail (LOD) refers to replacing high-resolution meshes with lower-resolution meshes in the distance, where details may not be significant. This technique can help reduce memory footprint and geometric aliasing. Most importantly, it has long been used to improve rasterization performance in games. But does that apply equally to ray tracing? The render time for rasterization…
