- the article presents what kind of artifacts happen when reconstructing normals from world space positions
- suggests how to reduce the artifacts by selecting triangles that are most likely to have originated from the same object
- additionally shows how to use compute shaders and group shared memory to optimize the reconstruction
- the paper presents a method that allows SDFs to be combined with techniques such as linear skinning
- this is achieved by calculating a triangle mesh hull for the SDF, applying the transformation to the hull and using this to trace
- tracing linearly in transformed space follows a non-linear trace in untransformed space
- overview of what has been improved in the latest apple GPU architecture and metal
- sparse textures, what it is, use cases and explanation of how to use it
- rasterization rate maps, mask that allows defining non-linear mapping between virtual and physical render targets
- vertex amplification specifies which vertex calculations can be shared between multiple viewports and which ones are unique per viewport
- better argument buffers, allow access to 500k textures and multiple levels of indirection
- the paper presents a new scheme that allows selectively combining different Monte Carlo rendering algorithms
- allow the use of less computational complex algorithms for more straightforward light transport cases and more sophisticated algorithms for more complicated cases
- enables to reduce the overall amount of noise in the same render time
- the article explains how vertex shaders in “Our Machinery” engine is handled
- all vertex data is explicitly loaded in the vertex shader
- shows how a more flexible skinning variation can be implemented
