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 is…
]]>Optimizing real-time graphics applications for maximum performance can be a challenging endeavor, and ray tracing is no exception. Whether you want to make your graphics engine more efficient overall or find a specific performance bottleneck, profiling is the most important tool to achieve your goals. Despite constantly improving support for ray tracing APIs in profilers such as Nsight Graphics…
]]>“Ray tracing is the future, and it always will be!” has been the tongue-in-cheek phrase used by graphics developers for decades when asked whether real-time ray tracing will ever be feasible. Everyone seems to agree on the first part: ray tracing is the future. That’s because ray tracing is the only technology we know of that enables the rendering of truly photorealistic images.
