Meshlet compression
We show how to diminish the memory footprint of meshlet geometry, thus both the index buffer and the vertex attributes. Decompression then happens on the fly on every frame in the mesh...
The new Wave Matrix Multiply Accumulate (WMMA) instructions added in HLSL Shader Model 6.8 allow shader developers to accelerate Generalized Matrix Multiplication (GEMM) matrix operations of the form:
WMMA instructions task all threads in a wave to collaboratively perform a matrix-multiply operation with higher efficiency and throughput than previously achievable using SM 6.7 or earlier instructions.
GEMM operations have many uses in in signal-processing, physics simulations, machine learning, and computer vision.
Some examples include:
- Performing Fast-Fourier Transforms for signal processing, such as audio, radio, or radar applications
- Applying filters and post-processing to images
- Calculating deformation of objects and fluids, such as fluid/physics sim or molecular simulation
- Implementing deep learning operators – for example convolution, multi-layer-perceptron, neural radiance fields, and so on.
