Real-Time Ray Tracing of Micro-Poly Geometry with Hierarchical Level of Detail

  • the paper introduces a method that enables micro-poly geometry for raytracing workloads
  • geometry is preprocessed, clusters formed and simplified into a compressed hierarchical level of detail representation
  • presents how using clusters enables fast BVH building
  • in the appendix discusses in detail how to select clusters to be guaranteed crack-free between different clusters

  • the blog post announces the first public release of a new D3D12 feature called Work Graphs
  • shows how this feature enables GPU shaders to spawn further GPU work from the GPU timeline
  • presents an overview of the spec
  • additionally, it discusses which samples are available at this time

GPU Work Graphs in Microsoft DirectX® 12

  • the AMD guide provides a more in-depth look at the practical use of D3D12 Work Graphs
  • presents how to get started and the building blocks of the programming model
  • additionally, it presents a section on tips & tricks to help during the development (guides for tracking down issues, best practices, etc.)
