- summary of
- cloud modeling and authoring system
- lighting model
- high level overview of the implementation
- environment lighting is using several distributed area lights
- distribution / strength is adapted to the environment
- implementation of importance sampling using varying step sizes for ray marching steps
- investigation of relation between linear interpolation and curve representations
- D3D11 extensions to simplify use of Lens Matched Shading and Multi-Res Shading
- short overview of the concepts and how the API works
- vulkan function calls pass through several layers until the actual function is executed
- looks at the disassembly to evaluate the cost of this (between 1-5%)
- and how to bypass many layers to reduce the overhead
- 100% dynamic lights, 16 shadow maps in 4kx4k atlas
- gbuffer breakdown
- stores material index in gbuffer, indexing into structured buffer for material information
- deferred decals have problems with depth discontinuities because of wrong mip selections
- use mip0 when depth discontinues are found around the pixel
- object decals, blending arbitrary meshes into the gbuffer
- working on bindless decals, follow the same pattern as clustered deferred lighting
- implementation of a buffer based (breadth first) approach for the raytracer
- looking at synchronization issues, performance
- brief look at the NVidia nsight tool
- overview of what error metric he uses when working/comparing encoders
- shows effect of different ray marching step sizes for screen space reflections
- diffuse reflections approximation with mip selection vs reference implementation with many samples
- comparison of backface culling efficiency for cluster cone, 64-triangle clusters
- discusses 3 different approaches for implementing thermal erosion on a height field based terrain
- supports perceptual metric for compression
- designed for opaque textures
- descriptor types in vulkan vs D3D12
- how to specify resource bindings for vulkan in HLSL
- memory layout rules
