LiteFX::Rendering::Backends::DirectX12BottomLevelAccelerationStructure

`LiteFX::Rendering::Backends::DirectX12BottomLevelAccelerationStructure`¶

Implements a DirectX 12 bottom-level acceleration structure (BLAS).

Synopsis¶

Declared in <litefx/backends/dx12.hpp>

class [[dllimport, dllexport]] DirectX12BottomLevelAccelerationStructure final
    : public IBottomLevelAccelerationStructure
    , public virtual StateResource
    , public virtual IDirectX12AccelerationStructure

Base Classes¶

Name	Description
`IBottomLevelAccelerationStructure`	A structure that holds a singular entity of geometry for hardware ray-tracing.
`StateResource`	Base class for a resource that can be identified by a name string within a `DeviceState`.
`IDirectX12AccelerationStructure`	Represents the base interface for a DirectX 12 acceleration structure implementation.

Types¶

Name	Description
`BoundingBoxes`	Stores a buffer that contains axis-aligned bounding boxes.
`TriangleMesh`	Represents a triangle mesh.

Member Functions¶

Name	Description
`DirectX12BottomLevelAccelerationStructure` [constructor]	Initializes a new DirectX 12 bottom-level acceleration structure (BLAS).
`~DirectX12BottomLevelAccelerationStructure` [destructor] [virtual]	Destructor
`operator=`	Assignment operators
`addBoundingBox`	Adds a buffer containing axis-aligned bounding boxes to the BLAS.
`addTriangleMesh`	Adds a triangle mesh to the BLAS.
`boundingBoxes` [virtual]	Returns an array of buffers, each containing axis-aligned bounding boxes stored in the BLAS.
`buffer`	Returns the acceleration structure backing buffer, that stores its last build.
`build`	Performs a complete build of the acceleration structure.
`clear` [virtual]	Clears all bounding boxes and triangle meshes from the acceleration structure.
`copy`	Copies the acceleration structure into the acceleration structure provided by `destination.`
`flags` [virtual]	Returns the flags that control how the acceleration structure should be built.
`name` [virtual]	Returns the name of the resource.
`offset` [virtual]	Returns the offset into `buffer` at which the acceleration structure is stored.
`remove`	`remove` overloads
`size` [virtual]	Returns the amount of memory in bytes inside `buffer` that store the acceleration structure.
`triangleMeshes` [virtual]	Returns an array of triangle meshes contained by the BLAS.
`update`	Performs an update on the acceleration structure.
`withBoundingBox`	Adds a buffer containing axis-aligned bounding boxes to the BLAS.
`withTriangleMesh`	Adds a triangle mesh to the BLAS.

Protected Member Functions¶

Name	Description
`operator=`	Assignment operators
`name`	Returns the name of the resource.
