OctaOctree Neural Radiosity for Real-time Glossy Material Rendering
Researchers have developed OctaOctree, a novel neural representation for rendering glossy materials in real-time global illumination. This method uses an adaptive octree in 3D space, with each node containing an octahedral directional map to capture radiance variations. By combining spatial hierarchy with direction-dependent storage, OctaOctree efficiently represents both diffuse and sharp glossy reflections, reducing the complexity for neural networks. AI
