Description

AMD releases Vulkan support for Dense Geometry Format is an AMD GPUOpen technical blog by Stuart Smith announcing the provisional Vulkan extension VK_AMDX_dense_geometry_format for Dense Geometry Format (DGF).

It recalls DGF as block-based geometry compression for future AMD GPUs, then shows feeding precompressed triangle data straight into acceleration-structure builds via a new geometry type and VkAccelerationStructureDenseGeometryFormatTrianglesDataAMDX. It covers filling metadata from the DGF SDK encoder or runtime decode, expected BLAS build-time and memory wins on native hardware, Adrenalin preview driver support, and a sample app.

It is for advanced Vulkan ray-tracing engineers integrating compressed geometry into BLAS builds. Prior BVH and DGF SDK knowledge helps.

Access is a free HTML post with API snippets, encoder command examples, and resource links for the extension and SDK.

It is useful when evaluating how to ship DGF-compressed meshes into Vulkan ray tracing without a separate decode pass.
