allocateGlobalDescriptors overloads

Synopses

Declared in <litefx/backends/vulkan.hpp>

Allocates a descriptor range with a capacity of descriptors from the global descriptor heap indicated by heapType. This overload allocates a raw descriptor range from a global descriptor heap. It is intended for interop purposes, where external libraries need to bind resources, as well as bindless rendering using SM 6.6 dynamic resources (ResourceDescriptorHeap/SamplerDescriptorHeap).

[[dllimport, nodiscard, dllexport]] virtual UniquePtr<VulkanDescriptorRange> allocateGlobalDescriptors(
    DescriptorHeapType heapType,
    UInt32 descriptors) const override;

Return Value

• A pointer to the descriptor range.
• The allocation for the descriptor set at the descriptor heap indicated by heapType.

Note

The return value should not be discarded.

Parameters

Name	Description
heapType	The global descriptor heap from which to allocate the descriptor range.
descriptors	The number of descriptors to allocate from the descriptor range.
descriptorSet	The descriptor set containing the descriptors to update.
