Description

VkAccelerationStructureInfoNV contains information that is used both for acceleration structure creation with vkCreateAccelerationStructureNV and in combination with the actual geometric data to build the acceleration structure with CmdBuildAccelerationStructureNV.

Valid Usage
- geometryCount must be less than or equal to VkPhysicalDeviceRayTracingPropertiesNV::maxGeometryCount
- instanceCount must be less than or equal to VkPhysicalDeviceRayTracingPropertiesNV::maxInstanceCount
- The total number of triangles in all geometries must be less than or equal to VkPhysicalDeviceRayTracingPropertiesNV::maxTriangleCount
- If type is ACCELERATION_STRUCTURE_TYPE_TOP_LEVEL_NV then geometryCount must be 0
- If type is ACCELERATION_STRUCTURE_TYPE_BOTTOM_LEVEL_NV then instanceCount must be 0
- If type is ACCELERATION_STRUCTURE_TYPE_BOTTOM_LEVEL_NV then the geometryType member of each geometry in pGeometries must be the same
- If flags has the BUILD_ACCELERATION_STRUCTURE_PREFER_FAST_TRACE_BIT_NV bit set, then it must not have the BUILD_ACCELERATION_STRUCTURE_PREFER_FAST_BUILD_BIT_NV bit set
- scratch must have been created with BUFFER_USAGE_RAY_TRACING_BIT_NV usage flag
- If instanceData is not NULL_HANDLE, instanceData must have been created with BUFFER_USAGE_RAY_TRACING_BIT_NV usage flag
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_ACCELERATION_STRUCTURE_INFO_NV
- pNext must be NULL
- type must be a valid VkAccelerationStructureTypeNV value
- flags must be a valid combination of VkBuildAccelerationStructureFlagBitsNV values
- If geometryCount is not 0, pGeometries must be a valid pointer to an array of geometryCount valid VkGeometryNV structures
