LiteFX::Rendering::DescriptorAllocationRange

Stores the relative location of a descriptor within a DescriptorAllocationLayout in a descriptor heap.

Synopsis

Declared in <litefx/rendering_api.hpp>

struct [[dllimport, dllexport]] DescriptorAllocationRange final

Description

Using traditional IDescriptorSet "IDescriptorSets", a descriptor allocation range stores the number of descriptors (for descriptor arrays), as well as the relative offset to the start of a descriptor set allocation. For a raw descriptor heap allocation, DescriptorAllocationRange::RelativeOffset directly maps to the offset within the descriptor heap. Think about it as a relative offset to the start of the heap.

A descriptor allocation range does not refer to an actual allocation, but is rather part of a DescriptorAllocationLayout that defines how an allocation on a heap looks like.

Data Members

Name	Description
Binding	Stores the binding point of the descriptor slot in a IDescriptorSet.
DescriptorCount	The number of descriptors in an allocated descriptor array.
Heap	The descriptor heap from which to allocate the descriptors.
RelativeOffset	The offset to the start of a IDescriptorSet, or a descriptor heap.
Unbounded	true if the descriptor is an unbounded runtime array, in which case (DescriptorCount is 0) and false otherwise.
