Mesh and task shaders (amplification shaders in D3D jargon) are a new way to process geometry in 3D applications. First proposed by NVidia in 2018 and initially available in the “Turing” series, they are now supported on RDNA2 GPUs and are part of the D3D12 API. There is also an extension in Vulkan (and a vendor-specific one in OpenGL). This post is about what mesh shadig is and next time I’m going to talk about how mesh/task shaders are implemented on the driver side.| Timur’s blog
Previously, I gave you an introduction to mesh/task shaders and wrote up some details about how mesh shaders are implemented in the driver. But I left out the important details of how task shaders (aka. amplification shaders) work in the driver. In this post, I aim to give you some details about how task shaders work under the hood. Like before, this is based on my experience implementing task shaders in RADV and all details are already public information.| Timur’s blog
