		const VmaAllocationCreateInfo &	allocationInfo,
		unsigned int	iElementSizeInBytes,
		unsigned int	iElementCount
	)

staticprivate

Creates a new buffer resource.

Parameters

pResourceManager	Owner resource manager.
sResourceName	Resource name, used for logging.
pMemoryAllocator	Allocator to create resource.
bufferInfo	Buffer creation info.
allocationInfo	Allocation creation info.
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.

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

◆ create() [3/3]

std::variant< std::unique_ptr< VulkanResource >, Error > ne::VulkanResource::create	(	VulkanResourceManager *	pResourceManager,
		const std::string &	sResourceName,
		VmaAllocator	pMemoryAllocator,
		const VkImageCreateInfo &	imageInfo,
		const VmaAllocationCreateInfo &	allocationInfo,
		std::optional< VkImageAspectFlags >	viewDescription,
		bool	bIsCubeMapView = `false`
	)

staticprivate

Creates a new image resource.

Parameters

pResourceManager	Owner resource manager.
sResourceName	Resource name, used for logging.
pMemoryAllocator	Allocator to create resource.
imageInfo	Image creation info.
allocationInfo	Allocation creation info.
viewDescription	If specified also creates an image view that references the image.
bIsCubeMapView	`true` to create a view to a cubemap, `false` to create a 2D texture view. Ignored if view description is not specified.

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

◆ getInternalBufferResource()

VkBuffer ne::VulkanResource::getInternalBufferResource ( ) const

inline

Returns internal buffer resource.

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

Returns: nullptr if this resource uses image as internal resource not a buffer, otherwise internal buffer resource.

◆ getInternalCubemapImageView()

VkImageView ne::VulkanResource::getInternalCubemapImageView ( size_t iCubemapFaceIndex = 0 )

inline

Returns internal image view for cubemap textures.

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

Parameters

iCubemapFaceIndex Index of the cubemap face to get the view to.

Returns: nullptr if this resource uses buffer as internal resource not an image or not a cubemap, otherwise internal image view.

◆ getInternalImage()

VkImage ne::VulkanResource::getInternalImage ( ) const

inline

Returns internal image.

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

Returns: nullptr if this resource uses buffer as internal resource not an image, otherwise internal image.

◆ getInternalImageView()

VkImageView ne::VulkanResource::getInternalImageView ( ) const

inline

Returns internal image view.

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

Returns: nullptr if this resource uses buffer as internal resource not an image, otherwise internal image view.

◆ getInternalImageViewDepthAspect()

VkImageView ne::VulkanResource::getInternalImageViewDepthAspect ( ) const

inline

Returns internal image view that only references depth aspect of the image.

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

Returns: Image view that only references depth aspect if the image was created with depth and stencil aspects, otherwise nullptr.

◆ getInternalResourceMemory()

std::pair< std::recursive_mutex, VmaAllocation > * ne::VulkanResource::getInternalResourceMemory ( )

inline

Returns memory allocation of the internal resource.

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

Returns: Memory allocation of the internal resource.

Member Data Documentation

◆ mtxResourceMemory

std::pair<std::recursive_mutex, VmaAllocation> ne::VulkanResource::mtxResourceMemory

private

Allocated memory for created resource.

Remarks: Using mutex because "access to a VmaAllocation object must be externally synchronized".

◆ optionalKtxTexture

std::optional<ktxVulkanTexture> ne::VulkanResource::optionalKtxTexture

private

Not empty if the object was created as a wrapper around KTX texture.

◆ pBufferResource

VkBuffer ne::VulkanResource::pBufferResource = nullptr

private

Created buffer Vulkan resource.

Remarks: nullptr if pImageResource is used.

◆ pDepthAspectImageView

VkImageView ne::VulkanResource::pDepthAspectImageView = nullptr

private

Optional view that references pImageResource depth aspect.

Remarks: Only used when pImageResource specified both depth and stencil aspects.

◆ pImageResource

VkImage ne::VulkanResource::pImageResource = nullptr

private

Created image Vulkan resource.

Remarks: nullptr if pBufferResource is used.

◆ pImageView

VkImageView ne::VulkanResource::pImageView = nullptr

private

Optional view that references pImageResource.

◆ vCubeMapViews

std::vector<VkImageView> ne::VulkanResource::vCubeMapViews

private

Views to each face of the cubemap texture (only valid if the resource is a cubemap texture).
