TODOs: - abstract away the staging cache insert/overwrite - check dependants of TLAS after creation of BLAS - insert the ASes into staging cache - collect the BLASes to use during TLAS builds
Finish getting build sizes for BLAS and TLAS Also ask for minimum allocation size constraint of the allocator
…cause that's supposed to be the "expensive" call Also prevent attempting to map the same memory multiple times (relevant in APIs that only allow a single mapping and we suballocate from same `IDeviceMemoryAllocation`) So now for a ReBAR upload to succeed, the memory allocation given out needs to be on the correct heap AND start off mapped (Asset Converter won't attempt to map by itself).
…Vulkan debug names on the created GPU objects right away. Push conversion requests to right after successful `assign` beause that makes more sense. Prep for host_image_copy support. Also make should-be-private structs private.
…Acceleration Structures to staging cache
…ssetConverter::reserve` TODO: make the staging cache refcounted with heterogenous (non-refcounted) lookup
…t, makes life a lot easier. add `IGPUTopLevelAccelerationStructure::getPendingBuildVer()` to detect if TLAS built yet also make sure the maxInstanceCount gets hashed properly
