NVIDIA Unveils Opacity Micro Maps to Enhance Ray Tracing Performance.
NVIDIA showcased the Opacity Micro Maps feature of the Ada Lovelace architecture, which can boost ray tracing performance by reducing the number of shader interactions with rays. Opacity Micro Maps can be used to speed up ray tracing performance whenever rays hit irregular objects, such as particles with empty spaces. The feature can also be used to turn a simple triangle into a leaf, resulting in a large gain in ray-traced performance. Game developers can check out the Opacity Micro Maps SDK available on GitHub to implement this feature.
