But you have to manage the data yourself and need to assemble and drive the operations on this data in the right way. These are exactly the things that the modern OpenGL API allows you to do more easily with vertex and fragment shaders. It allows to setup and assemble the rasterization p...

Radeon™ GPU Analyzer (RGA) 2.4.1 introduces support for DXR shaders in a new mode of the command line tool.Read how to get started using DirectX Raytracing with RGA 2.4.1. Related content Radeon GPU Analyzer is an offline compiler and performance analysis tool for DirectX®, Vulkan®...
Microsoft said in November 2019 that mesh shaders were reinventing the geometry pipeline. In November 2019, Khronos announced it would use Nvidia mesh shader code as an extension to Vulkan and OpenGL. Then finally, in March 2020, DirectX 12 Ultimate with Mesh Shaders was officially announced, ...

The unique hardware ray tracing processors, including coherence gathering engines, fixed function intersection testing array and accelerated scene hierarchy generator, receive rays from the shaders, determines their intersection and initiates more shaders. All of this is made possible with entirely dynamic...
