Constructor & Destructor Documentation

◆ DirectXResource()

ne::DirectXResource::DirectXResource	(	DirectXResourceManager *	pResourceManager,
		const std::string &	sResourceName,
		UINT	iElementSizeInBytes,
		UINT	iElementCount
	)

private

Constructor. Creates an empty resource.

Parameters

pResourceManager	Owner resource manager.
sResourceName	Name of this resource.
iElementSizeInBytes	Resource size information. Size of one array element (if array), otherwise specify size of the whole resource.
iElementCount	Resource size information. Total number of elements in the array (if array), otherwise specify 1.

Member Function Documentation

◆ bindDescriptor()

std::optional< Error > ne::DirectXResource::bindDescriptor	(	DirectXDescriptorType	descriptorType,
		ContinuousDirectXDescriptorRange *	pRange = `nullptr`,
		bool	bDontBindDescriptorToCubemapFaces = `false`
	)

Creates a new descriptor and binds it to this resource.

Remarks: Does nothing if a descriptor of this type is already binded.

Parameters

descriptorType	Type of descriptor to bind.
pRange	Specify in order to allocate a descriptor from this range.
bDontBindDescriptorToCubemapFaces	If this resource is a cubemap, specify `false` to also bind descriptors that reference cubemap faces, specify `true` to only bind 1 descriptor that references the entire resource.

Returns: Error if something went wrong.

◆ create()

std::variant< std::unique_ptr< DirectXResource >, Error > ne::DirectXResource::create	(	DirectXResourceManager *	pResourceManager,
		const std::string &	sResourceName,
		D3D12MA::Allocator *	pMemoryAllocator,
		const D3D12MA::ALLOCATION_DESC &	allocationDesc,
		const D3D12_RESOURCE_DESC &	resourceDesc,
		const D3D12_RESOURCE_STATES &	initialResourceState,
		std::optional< D3D12_CLEAR_VALUE >	resourceClearValue,
		size_t	iElementSizeInBytes = `0`,
		size_t	iElementCount = `0`
	)

staticprivate

Creates a new resource (without binding a descriptor to it).

Parameters

pResourceManager	Owner resource manager.
sResourceName	Resource name, used for logging.
pMemoryAllocator	Allocator to create resource.
allocationDesc	Allocation description.
resourceDesc	Resource description.
initialResourceState	Initial state of this resource.
resourceClearValue	Optimized clear value. Pass empty if creating CBV/SRV/UAV resource.
iElementSizeInBytes	Optional parameter. Specify if this resource represents an array. Used for SRV creation.
iElementCount	Optional parameter. Specify if this resource represents an array. Used for SRV creation.

Returns: Error if something went wrong, otherwise created resource.

◆ createResourceFromSwapChainBuffer()

std::variant< std::unique_ptr< DirectXResource >, Error > ne::DirectXResource::createResourceFromSwapChainBuffer	(	DirectXResourceManager *	pResourceManager,
		DirectXDescriptorHeap *	pRtvHeap,
		const ComPtr< ID3D12Resource > &	pSwapChainBuffer
	)

staticprivate

Creates a new resource instance by wrapping existing swap chain buffer, also binds RTV to the specified resource.

Parameters

pResourceManager	Owner resource manager.
pRtvHeap	Render target view heap manager.
pSwapChainBuffer	Swap chain buffer to wrap.

Returns: Error if something went wrong, otherwise created resource.

◆ getBindedCubemapFaceDescriptorCpuHandle()

std::optional< D3D12_CPU_DESCRIPTOR_HANDLE > ne::DirectXResource::getBindedCubemapFaceDescriptorCpuHandle	(	DirectXDescriptorType	descriptorType,
		size_t	iCubemapFaceIndex
	)

Returns descriptor handle to a cubemap face that was previously binded using bindDescriptor.

Parameters

descriptorType	Type of descriptor to get.
iCubemapFaceIndex	Index of the cubemap face to get descriptor handle to.

Returns: Empty this is not a cubemap resource or descriptor was not binded previously, otherwise descriptor handle.

◆ getBindedDescriptorCpuHandle()

std::optional< D3D12_CPU_DESCRIPTOR_HANDLE > ne::DirectXResource::getBindedDescriptorCpuHandle ( DirectXDescriptorType descriptorType )

Returns descriptor handle to the descriptor that was previously binded using bindDescriptor.

Parameters

descriptorType Type of descriptor to get.

Returns: Empty if descriptor if this type was not binded to this resource, otherwise descriptor handle.

◆ getBindedDescriptorGpuHandle()

std::optional< D3D12_GPU_DESCRIPTOR_HANDLE > ne::DirectXResource::getBindedDescriptorGpuHandle ( DirectXDescriptorType descriptorType )

Returns descriptor handle to the descriptor that was previously binded using bindDescriptor.

Parameters

descriptorType Type of descriptor to get.

Returns: Empty if descriptor if this type was not binded to this resource, otherwise descriptor handle.

◆ getDescriptor()

DirectXDescriptor * ne::DirectXResource::getDescriptor ( DirectXDescriptorType descriptorType )

Returns a raw (non-owning) pointer to a binded descriptor.

Remarks: Do not delete (free) returned pointer.

Parameters

descriptorType Type of descriptor to query.

Returns: nullptr if a descriptor of this type was not binded to this resource, otherwise valid pointer.

◆ getInternalResource()

ID3D12Resource * ne::DirectXResource::getInternalResource ( ) const

inline

Returns internal resource.

Remarks: Do not delete (free) this pointer.; Returned pointer is only valid while this object is valid.

Returns: Internal resource.

Member Data Documentation

◆ mtxHeapDescriptors

std::pair< std::recursive_mutex, std::array<DescriptorsSameType, static_cast<size_t>(DirectXDescriptorType::END)> > ne::DirectXResource::mtxHeapDescriptors

private

Array of descriptors used by this resource.

Remarks: Access elements like this: "vHeapDescriptors[DirectXDescriptorType::SRV]".; Some descriptors are nullptr. nullptr descriptor means that it's not set (not used).; There might be 6 descriptors of the same type if this resource is a cubemap, then each descriptor will reference a specific cubemap face.

◆ pAllocatedResource

ComPtr<D3D12MA::Allocation> ne::DirectXResource::pAllocatedResource

private

Created resource (can be empty if pSwapChainBuffer is used).

◆ pInternalResource

ID3D12Resource* ne::DirectXResource::pInternalResource = nullptr

private

Pointer to pSwapChainBuffer or pAllocatedResource used for fast access to internal resource.

◆ pSwapChainBuffer

ComPtr<ID3D12Resource> ne::DirectXResource::pSwapChainBuffer

private

Used when resource was created from swap chain buffer (can be empty if pAllocatedResource is used).
