Member Data Documentation

BufferOffset

Uint64 Diligent::SparseBufferMemoryBindRange::BufferOffset = 0

Offset in buffer address space where memory will be bound/unbound.

Must be a multiple of the SparseBufferProperties::BlockSize.

MemoryOffset

Uint64 Diligent::SparseBufferMemoryBindRange::MemoryOffset = 0

Memory range offset in pMemory.

Must be a multiple of the SparseBufferProperties::BlockSize.

MemorySize

Uint64 Diligent::SparseBufferMemoryBindRange::MemorySize = 0

Size of the memory which will be bound/unbound.

Must be a multiple of the SparseBufferProperties::BlockSize.

pMemory

IDeviceMemory* Diligent::SparseBufferMemoryBindRange::pMemory = nullptr

Pointer to the memory object.

If non-null, the memory will be bound to the Region; otherwise the memory will be unbound.

Remarks

• Direct3D11: the entire buffer must use a single memory object. When a resource is bound to a new memory object, all previous bindings are invalidated.
• Vulkan & Direct3D12: different resource regions may be bound to different memory objects.
• Vulkan: memory object must be compatible with the resource, use IDeviceMemory::IsCompatible() to ensure that.

Note

Memory object can be created by the engine using IRenderDevice::CreateDeviceMemory() or can be implemented by the user. Memory object must implement interface methods for each backend (IDeviceMemoryD3D11, IDeviceMemoryD3D12, IDeviceMemoryVk).
