The vulkan\n\u003e extension `VK_NV_displacement_micromap` is no longer available.\n\u003e\n\u003e We recommend exploring [**NVIDIA RTX Mega\n\u003e Geometry**](https://developer.nvidia.com/blog/nvidia-rtx-mega-geometry-now-available-with-new-vulkan-samples/),\n\u003e which can provide similar functionality with greater flexibility. See\n\u003e [vk_tessellated_clusters](https://github.com/nvpro-samples/vk_tessellated_clusters),\n\u003e which demonstrates raytracing displacement with Vulkan.\n\n# NVIDIA Displacement Micro-Map SDK\n\nFor more information about NVIDIA Micro-Mesh Technology visit [NVIDIA developer](https://developer.nvidia.com/rtx/ray-tracing/micro-mesh)\n\nThe libraries in this repository aid 3D asset content creation using displacement Micro-Maps.\nPlease refer to the [NVIDIA Displacement-MicroMap-Toolkit](https://github.com/NVIDIAGameWorks/Displacement-MicroMap-Toolkit) to see them being used.\n\nThis SDK provides a low-level API meant for embedding in other applications and tools.\nIt has a C-style API as well as an API agnostic GPU interface to facilitate this. \nAs a result it is sometimes a bit less easy to use. All functionality is provided\nthrough the `micromesh` namespace and it makes frequent use of the `micromesh::ArrayInfo`\nstructure, which allows it to pass data as a pointer \u0026 stride combination. All user visible data\nis allocated by the user, so some operations are executed in two steps where a *micromeshOpSomethingBegin* returns\nthe sizing required, while *micromeshOpSomethingEnd* completes it. One can also abort such \noperations with *micromeshOpContextAbort*. The `micromesh::Context` therefore is stateful\nbut fairly lightweight, in case you want to create one per thread. Right now there is also some rudimentary\nautomatic threading within the context.\n\n- [`micromesh_core`](/micromesh_core/README.md): Library for basic data structures, utilities and operations to create or modify micromap and micromesh data.\n- [`micromesh_displacement_compression`](/micromesh_displacement_compression/README.md): Library that handles the compression of displacement micromaps.\n- [`micromesh_displacement_remeshing`](/micromesh_displacement_remeshing/README.md): Library for GPU-based remeshing (currently only a Vulkan/SPIR-V based implementation for the GPU exists).\n\n## About the Latest Release\n\nVersion 2.1\n\n- Add OpTessellateMesh_input::pfnProvideTriangleVertices for control over the\n  output location.\n- Add micromeshOpChangeLayoutPacked for format conversion\n- Fixed bugs in compressor bit packing\n\nVersion 2.0\n\n- API break: micromesh::OpGrowTriangleSelection_input::topology is now a const array\n- Fix UB in compressor due to possible negative shifts\n- Step towards remesher determinism\n\n## Support Contact\n\nFeel free to file issues directly on the GitHub page or reach out to NVIDIA at\n\u003cdisplacedmicromesh-sdk-support@nvidia.com\u003e\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnvidiagameworks%2Fdisplacement-micromap-sdk","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnvidiagameworks%2Fdisplacement-micromap-sdk","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnvidiagameworks%2Fdisplacement-micromap-sdk/lists"}
