Title:
- Directional Occlusion via Multi-Irradiance Mapping
Presenter(s)/Author(s):
Abstract:
We present a new, physically plausible, real-time approach to compute directional occlusion for dynamic objects, lit with image based lighting. For this, we partition the hemisphere into multiple sectors and pre-convolve these into separate irradiance maps. At runtime the contributions of each sector are then individually occluded and summed together.
