Triangle Visibility Buffer [wayback-archive]

• in-depth walkthrough of the GPU triangle culling pipeline
• render into a single render RGBA8 render target, storing drawID + triangle ID
• memory usage comparison with deferred shading
• at shading time
  • lookup the triangle ID from the render target
  • interpolate vertex attributes at pixel position
  • apply shading
• advantages of the technique
  • less memory bandwidth required
  • better memory coherence during shading
  • more material variety, no need to store material data in gbuffers

Re-Testing Vulkan Transform Data Handling Strategies [wayback-archive]

• performance comparison of constant buffer data stored in
  • push-constants
  • large UBO (device / host memory)
  • large SSBO (device / host memory)
• on Nvidia UBO performs significantly better

Octahedral Impostors [wayback-archive]

• better usage of texture space, workflow improvements
• overview of billboard techniques
• using either Hemi-Octahedron or full Octahedron
• how to blend between the different baked directions
• integration into UE pipeline

substance PBR guide [wayback-archive]

• updated version of the guide in two parts 1, 2

• comparison of crunch (unity improved version) with DDS + general purpose compressors

V-EZ brings “Easy Mode” to Vulkan [wayback-archive]

• abstraction layer on-top of vulkan
• implements automatic render barrier management, descriptor pools/sets, memory management, render passes, etc.
• aimed at CAD software, not games
• not open source at this point

An Idea: Raytracing Lookup Tables [wayback-archive]

• instead of using textures use adaptive-meshes to represent data where required, raytrace against that mesh to get the lookup value

PIX 1803.25 – GPU Occupancy, CPU sampling, automatic shader PDB resolution, and more [wayback-archive]

• allows to see occupancy broken down into different render pipeline stages (NVidia only for now)
• improved CPU profiling
• more memory usage information (command allocators, PSO, descriptor heaps)
• geometry shader and DXR debug support
