Abstract:
A method and apparatus for ray tracing may include a method, manufacture and apparatus for ray tracing that may include dividing a render target into a plurality of bins. Next, a visibility pass is performed using ray tracing to generate a visibility stream such that the visibility stream indicates, for each bin of the plurality of bins, which primitives are visible in the bin. Then, for at least one bin of the plurality of bins, each primitive in the bin that is indicated in the visibility stream as being visible in the bin is rendered.
