LiteFX::Rendering::DescriptorType

Describes the type of a IDescriptorLayout.

Synopsis

Declared in <litefx/rendering_api.hpp>

enum class DescriptorType : int;

Description

Note that, while in theory you can declare a writable descriptor in any format, the rendering back-end might not necessarily support writing in a specific format.

Members

Name	Description
ConstantBuffer	A uniform buffer in Vulkan. Maps to a constant buffer in DirectX.
StructuredBuffer	A shader storage buffer object in Vulkan. Maps to a structured buffer in DirectX.
RWStructuredBuffer	A writable shader storage object in Vulkan. Maps to a read/write structured buffer in DirectX.
Texture	A read-only sampled image.
RWTexture	A writable image.
Sampler	A sampler state of a texture or image.
InputAttachment	The result of a render target from an earlier render pass. Maps to a SubpassInput in HLSL.
Buffer	Represents a read-only texel buffer (uniform texel buffer).
RWBuffer	Represents a writable texel buffer (storage texel buffer).
ByteAddressBuffer	Represents an unformatted buffer.
RWByteAddressBuffer	Represents an unformatted writable buffer.
AccelerationStructure	Represents a ray-tracing acceleration structure.
ResourceDescriptorHeap	Special descriptor type, that can bind all resources besides constant buffers, acceleration structures and samplers, which then can be directly indexed from the global resource heap.
SamplerDescriptorHeap	A special descriptor type that allows indexed access to the a portion of the global sampler heap.
