It is never mentioned explicitly, but my hunch would be that primary visibility is still done using rasterisation and that ray tracing is only used for reflections, shadows and ambient occlusion.
This is how most film rendering was done ten years ago too.
- bufferoverflow 8y agoThey are properly raytracing soft shadows, no need for AO.
- swerner 8y agoAO and soft shadows are orthogonal and are often used simultaneously. A few direct light sources (point lights, spots, infinite) with soft shadows and additionally an environment light (dome or half dome) with AO.
