-**Converting VK_NV_ray_tracing to VK_KHR_ray_tracing**
-
-This document is a quick guide on what need to be changed to convert an existing application 
-using NV ray tracing extension to KHR.
-
-# The Obvious
-
-For most structures and enum, the ending with NV can be replaced with KHR. 
-
-This is true for example for:
-
-Some examples:
-
-      NVIDIA                   |         KHRONOS
--------------------------------|-----------------------------
-VK_SHADER_STAGE_RAYGEN_BIT_NV | VK_SHADER_STAGE_RAYGEN_BIT_KHR 
-VK_SHADER_STAGE_CLOSEST_HIT_BIT_NV | VK_SHADER_STAGE_CLOSEST_HIT_BIT_KHR
-VK_GEOMETRY_INSTANCE_TRIANGLE_CULL_DISABLE_BIT_NV | VK_GEOMETRY_INSTANCE_TRIANGLE_CULL_DISABLE_BIT_KHR
-VK_GEOMETRY_INSTANCE_FORCE_OPAQUE_BIT_NV | VK_GEOMETRY_INSTANCE_FORCE_OPAQUE_BIT_KHR
-[Types and Flags]
-
-NVIDIA                   |         KHRONOS
--------------------------------|-----------------------------
- VkWriteDescriptorSetAccelerationStructureNV |  VkWriteDescriptorSetAccelerationStructureKHR
- VkRayTracingShaderGroupCreateInfoNV |  VkRayTracingShaderGroupCreateInfoKHR
- VkRayTracingPipelineCreateInfoNV |  VkRayTracingPipelineCreateInfoKHR
-[Structures]
-
-
-# Handles version Device Addresses -> memory allocations
-
-With KHR, we no longer pass the buffer or an handle, but the `vk::DeviceAddress`. 
-First, when allocating a buffer, it has to have the `VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT` flag.
-Similarly, the memory associated with this buffer, needs also the `VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT` flag.
-
-For the memory allocation, this could be done like this:
-
-~~~~ C++
-vk::MemoryAllocateFlagsInfo memFlagInfo;
-memFlagInfo.setFlags(vk::MemoryAllocateFlagBits::eDeviceAddress);
-
-vk::MemoryAllocateInfo memAlloc;
-memAlloc.setPNext(&memFlagInfo);
-// Allocate memory
-~~~~
-
-The buffer address could then be retrieved like this:
-
-~~~~ C++
-vk::DeviceAddress vertexAddress = m_device.getBufferAddress({model.vertexBuffer.buffer});
-~~~~
-
-# Where is GeometryNV?
-
-The structure to create BLAS was replaced by different structures. 
-
-* `vk::AccelerationStructureCreateGeometryTypeInfoKHR` : describe how the acceleration structure is created. It is an indication how large it could be.
-* `vk::AccelerationStructureGeometryKHR` : the geometry to build, addresses of vertices and indices
-* `vk::AccelerationStructureBuildOffsetInfoKHR` : the number of elements to build and offsets 
-
-Those three structures can be an array of each, meaning that a BLAS can be a combination fo multiple geometries.
-
-
-As an example on how those are filed. It returns `nvvkpp::RaytracingBuilderKHR::Blas` which has vectors
-of the above structures.
-
-~~~~ C++
-//--------------------------------------------------------------------------------------------------
-// Converting a OBJ primitive to the ray tracing geometry used for the BLAS
-//
-auto HelloVulkan::objectToVkGeometryKHR(const ObjModel& model)
-{
-  // Setting up the creation info of acceleration structure
-  vk::AccelerationStructureCreateGeometryTypeInfoKHR asCreate;
-  asCreate.setGeometryType(vk::GeometryTypeKHR::eTriangles);
-  asCreate.setIndexType(vk::IndexType::eUint32);
-  asCreate.setVertexFormat(vk::Format::eR32G32B32Sfloat);
-  asCreate.setMaxPrimitiveCount(model.nbIndices / 3);  // Nb triangles
-  asCreate.setMaxVertexCount(model.nbVertices);
-  asCreate.setAllowsTransforms(VK_FALSE);  // No adding transformation matrices
-
-  // Building part
-  vk::DeviceAddress vertexAddress = m_device.getBufferAddress({model.vertexBuffer.buffer});
-  vk::DeviceAddress indexAddress  = m_device.getBufferAddress({model.indexBuffer.buffer});
-
-  vk::AccelerationStructureGeometryTrianglesDataKHR triangles;
-  triangles.setVertexFormat(asCreate.vertexFormat);
-  triangles.setVertexData(vertexAddress);
-  triangles.setVertexStride(sizeof(VertexObj));
-  triangles.setIndexType(asCreate.indexType);
-  triangles.setIndexData(indexAddress);
-  triangles.setTransformData({});
-
-  // Setting up the build info of the acceleration
-  vk::AccelerationStructureGeometryKHR asGeom;
-  asGeom.setGeometryType(asCreate.geometryType);
-  asGeom.setFlags(vk::GeometryFlagBitsKHR::eOpaque);
-  asGeom.geometry.setTriangles(triangles);
-
-  // The primitive itself
-  vk::AccelerationStructureBuildOffsetInfoKHR offset;
-  offset.setFirstVertex(0);
-  offset.setPrimitiveCount(asCreate.maxPrimitiveCount);
-  offset.setPrimitiveOffset(0);
-  offset.setTransformOffset(0);
-
-  // Our blas is only one geometry, but could be made of many geometries
-  nvvkpp::RaytracingBuilderKHR::Blas blas;
-  blas.asGeometry.emplace_back(asGeom);
-  blas.asCreateGeometryInfo.emplace_back(asCreate);
-  blas.asBuildOffsetInfo.emplace_back(offset);
-
-  return blas;
-}
-~~~~ 
-
-
-# Creating and building BLAS/TLAS
-
-With the structures filled in, there are some similarities with the NVIDIA extension.
-
-## BLAS
-
-The construction of a BLAS AS will look like this:
-
-~~~~ C++ 
-vk::AccelerationStructureCreateInfoKHR asCreateInfo{{}, vk::AccelerationStructureTypeKHR::eBottomLevel};
-asCreateInfo.setFlags(vk::BuildAccelerationStructureFlagBitsKHR::ePreferFastTrace);
-asCreateInfo.setMaxGeometryCount((uint32_t)blas.asCreateGeometryInfo.size());
-asCreateInfo.setPGeometryInfos(blas.asCreateGeometryInfo.data());
-
-// Create an acceleration structure identifier and allocate memory to
-// store the resulting structure data
-blas.as = m_alloc.createAcceleration(asCreateInfo);
-~~~~ 
-
-To retrieve the memory requirements, there is a new flag, to be build on the host or the device.
-
-~~~~ C++
-vk::AccelerationStructureMemoryRequirementsInfoKHR memoryRequirementsInfo{
-  vk::AccelerationStructureMemoryRequirementsTypeKHR::eBuildScratch,
-  vk::AccelerationStructureBuildTypeKHR::eDevice, blas.as.accel};
-~~~~ 
-
-Building the acceleration structure requires to pass a pointer to the array of vk::AccelerationStructureGeometryKHR.
-
-~~~~ C++
-const vk::AccelerationStructureGeometryKHR*   pGeometry = blas.asGeometry.data();
-vk::AccelerationStructureBuildGeometryInfoKHR bottomASInfo{vk::AccelerationStructureTypeKHR::eBottomLevel};
-bottomASInfo.setFlags(flags);
-bottomASInfo.setUpdate(VK_FALSE);
-bottomASInfo.setSrcAccelerationStructure({});
-bottomASInfo.setDstAccelerationStructure(blas.as.accel);
-bottomASInfo.setGeometryArrayOfPointers(VK_FALSE);
-bottomASInfo.setGeometryCount((uint32_t)blas.asGeometry.size());
-bottomASInfo.setPpGeometries(&pGeometry);
-bottomASInfo.setScratchData(scratchAddress);
-~~~~ 
-
-
-It will be also necessary to create an array of pointers to the vk::AccelerationStructureBuildOffsetInfoKHR of each BLAS.
-
-~~~~ C++
-// Pointers of offset
-std::vector<const vk::AccelerationStructureBuildOffsetInfoKHR*> pBuildOffset(blas.asBuildOffsetInfo.size());
-for(size_t i = 0; i < blas.asBuildOffsetInfo.size(); i++)
-  pBuildOffset[i] = &blas.asBuildOffsetInfo[i];
-~~~~ 
-
-## TLAS
-
-The same structures are now used to build the top-level, using instances as the type of geometry.
-
-FOr example, here how can be created the AS for an array of instances
-
-~~~~ C++
-vk::AccelerationStructureCreateGeometryTypeInfoKHR geometryCreate{vk::GeometryTypeKHR::eInstances};
-geometryCreate.setMaxPrimitiveCount(static_cast<uint32_t>(instances.size()));
-geometryCreate.setAllowsTransforms(VK_TRUE);
-
-vk::AccelerationStructureCreateInfoKHR asCreateInfo{{}, vk::AccelerationStructureTypeKHR::eTopLevel};
-asCreateInfo.setFlags(flags);
-asCreateInfo.setMaxGeometryCount(1);
-asCreateInfo.setPGeometryInfos(&geometryCreate);
-
-// Create the acceleration structure object and allocate the memory
-// required to hold the TLAS data
-m_tlas.as = m_alloc.createAcceleration(asCreateInfo);
-~~~~
-
-
-
-
-Also, there are now a structure to hold the instances `vk::AccelerationStructureInstanceKHR`
-You will need to fill an array with all the information, create a buffer and use 
-the address to set the geometry
-
-~~~~ C++
-// Allocate the instance buffer and copy its contents from host to device
-// memory
-m_instBuffer = m_alloc.createBuffer(cmdBuf, geometryInstances,
-                                    vk::BufferUsageFlagBits::eRayTracingKHR | vk::BufferUsageFlagBits::eShaderDeviceAddress);
-m_debug.setObjectName(m_instBuffer.buffer, "TLASInstances");
-vk::DeviceAddress instanceAddress = m_device.getBufferAddress(m_instBuffer.buffer);
-
-vk::AccelerationStructureGeometryKHR topASGeometry{vk::GeometryTypeKHR::eInstances};
-topASGeometry.geometry.instances.setArrayOfPointers(VK_FALSE);
-topASGeometry.geometry.instances.setData(instanceAddress);
-~~~~ 
-
-
-
-
-# Calling TraceRaysKHR
-
-This is very close to the NVIDIA version, the difference is instead of passing buffer addresses, offsets, strides,
-for each stages, we have to fill vk::StridedBufferRegionKHR structure of each stages, which have
-the same parameters: buffer, offset, stride and SBT size 
-
-Example:
-
-~~~~ C++
-vk::DeviceSize sbtSize = progSize * (vk::DeviceSize)m_rtShaderGroups.size();
-
-const vk::StridedBufferRegionKHR raygenShaderBindingTable = {m_rtSBTBuffer.buffer, rayGenOffset,
-                                                             progSize, sbtSize};
-const vk::StridedBufferRegionKHR missShaderBindingTable   = {m_rtSBTBuffer.buffer, missOffset,
-                                                           progSize, sbtSize};
-const vk::StridedBufferRegionKHR hitShaderBindingTable    = {m_rtSBTBuffer.buffer, hitGroupOffset,
-                                                          progSize, sbtSize};
-const vk::StridedBufferRegionKHR callableShaderBindingTable;
-
-cmdBuf.traceRaysKHR(&raygenShaderBindingTable, &missShaderBindingTable, &hitShaderBindingTable,
-                    &callableShaderBindingTable,      //
-                    m_size.width, m_size.height, 1);  //
-

-## Latest Vulkan SDK
-
-This repository tries to always be up to date with the latest Vulkan SDK, therefore we suggest to download and install it.
-Version 1.2.162.0 and up has ray tracing extensions support.
-
-**Vulkan SDK**: https://vulkan.lunarg.com/sdk/home
-
-
-## Driver
-
-NVIDIA driver 450.0 and up support Vulkan ray tracing. 
-
-* Standard driver: https://www.nvidia.com/Download/index.aspx
-* Vulkan beta driver: https://developer.nvidia.com/vulkan-driver
-
-
-## CMake
-
-The CMakefile will use other makefiles from `nvpro_core` and look for Vulkan environment variables for the installation of the SDK. Therefore, it is important to have all the above installed before running Cmake in the 
-`vk_raytracing_tutorial_KHR` directory.
-
-**Note:** Ray tracing only works with 64 bit environment. Therefore, make sure to choose the right build environment.
-
-**Note:** If you are using your own Vulkan header files, it is possible to overide the default search path.
-  Modify `VULKAN > VULKAN_HEADERS_OVERRIDE_INCLUDE_DIR` to the path to beta vulkan headers.
-
-## Starting From Extra Tutorial
-
-All _extra_ tutorials are starting from the end result of the _first tutorial_. The directory of the _extra_ tutorials is the end result of doing it. 
-
-To start the tutorial from the begining.
-
-* Make a copy of the ray_tutorial__simple (backup)
-* Follow the tutorial by modifying ray_tutorial__simple
