Member Data Documentation

Pool* D3D12MA::ALLOCATION_DESC::CustomPool

Custom pool to place the new resource in. Optional.

When not NULL, the resource will be created inside specified custom pool.

D3D12_HEAP_FLAGS D3D12MA::ALLOCATION_DESC::ExtraHeapFlags

Additional heap flags to be used when allocating memory.

In most cases it can be 0.

If you use D3D12MA::Allocator::CreateResource(), you don't need to care. Necessary flag D3D12_HEAP_FLAG_ALLOW_ONLY_BUFFERS, D3D12_HEAP_FLAG_ALLOW_ONLY_NON_RT_DS_TEXTURES, or D3D12_HEAP_FLAG_ALLOW_ONLY_RT_DS_TEXTURES is added automatically.
If you use D3D12MA::Allocator::AllocateMemory(), you should specify one of those ALLOW_ONLY flags. Except when you validate that D3D12MA::Allocator::GetD3D12Options().ResourceHeapTier == D3D12_RESOURCE_HEAP_TIER_1 - then you can leave it 0.
You can specify additional flags if needed. Then the memory will always be allocated as separate block using D3D12Device::CreateCommittedResource or CreateHeap, not as part of an existing larget block.

When D3D12MA::ALLOCATION_DESC::CustomPool != NULL this member is ignored.

ALLOCATION_FLAGS D3D12MA::ALLOCATION_DESC::Flags

Flags.

D3D12_HEAP_TYPE D3D12MA::ALLOCATION_DESC::HeapType

The type of memory heap where the new allocation should be placed.

It must be one of: D3D12_HEAP_TYPE_DEFAULT, D3D12_HEAP_TYPE_UPLOAD, D3D12_HEAP_TYPE_READBACK.

When D3D12MA::ALLOCATION_DESC::CustomPool != NULL this member is ignored.

void* D3D12MA::ALLOCATION_DESC::pPrivateData

Custom general-purpose pointer that will be stored in D3D12MA::Allocation.
