Function Documentation

◆ ktxTexture1_GetVkFormat()

VkFormat ktxTexture1_GetVkFormat ( ktxTexture1 * This )

Return the VkFormat enum of a ktxTexture1 object.

Returns: The VkFormat of the texture object. May return VK_FORMAT_UNDEFINED if there is no mapping from the GL internalformat and format.

◆ ktxTexture1_VkUpload()

KTX_error_code ktxTexture1_VkUpload	(	ktxTexture1 *	texture,
		ktxVulkanDeviceInfo *	vdi,
		ktxVulkanTexture *	vkTexture )

Create a Vulkan image object from a ktxTexture1 object.

Calls ktxTexture_VkUploadEx() with the most commonly used options: VK_IMAGE_TILING_OPTIMAL, VK_IMAGE_USAGE_SAMPLED_BIT and VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL. Use that for complete control.

◆ ktxTexture1_VkUploadEx()

KTX_error_code ktxTexture1_VkUploadEx	(	ktxTexture1 *	This,
		ktxVulkanDeviceInfo *	vdi,
		ktxVulkanTexture *	vkTexture,
		VkImageTiling	tiling,
		VkImageUsageFlags	usageFlags,
		VkImageLayout	finalLayout )

Create a Vulkan image object from a ktxTexture1 object.

This simply calls ktxTexture_VkUploadEx().

◆ ktxTexture1_VkUploadEx_WithSuballocator()

KTX_error_code ktxTexture1_VkUploadEx_WithSuballocator	(	ktxTexture1 *	This,
		ktxVulkanDeviceInfo *	vdi,
		ktxVulkanTexture *	vkTexture,
		VkImageTiling	tiling,
		VkImageUsageFlags	usageFlags,
		VkImageLayout	finalLayout,
		ktxVulkanTexture_subAllocatorCallbacks *	subAllocatorCallbacks )

Create a Vulkan image object from a ktxTexture1 object.

This simply calls ktxTexture_VkUploadEx_WithSuballocator()

Creates a VkImage with VkFormat etc. matching the KTX data and uploads the images. Mipmaps will be generated if the ktxTexture's generateMipmaps flag is set. Returns the handles of the created objects and information about the texture in the ktxVulkanTexture pointed at by vkTexture.

The created VkImage will have VK_SHARING_MODE_EXCLUSIVE set thus the resulting image will be usable only with queues of the same family as the queue in the ktxVulkanDeviceInfo pointed to by vdi.

usageFlags and thus acceptable usage of the created image may be augmented as follows:

with VK_IMAGE_USAGE_TRANSFER_DST_BIT if tiling is VK_IMAGE_TILING_OPTIMAL
with VK_IMAGE_USAGE_TRANSFER_DST_BIT | VK_IMAGE_USAGE_TRANSFER_SRC_BIT if generateMipmaps is set in the ktxTexture.

Most Vulkan implementations support VK_IMAGE_TILING_LINEAR only for a very limited number of formats and features. Generally VK_IMAGE_TILING_OPTIMAL is preferred. The latter requires a staging buffer so will use more memory during loading.

If a pointer to a set of suballocator callbacks is provided, they will be used instead of manual allocation of VkDeviceMemory. A 64 bit uint that references the suballocated page(s) is returned on memory procurement and saved in the allocationId field of the structure pointed to by vkTexture.

Parameters

[in]	This	pointer to the ktxTexture from which to upload.
[in]	vdi	pointer to a ktxVulkanDeviceInfo structure providing information about the Vulkan device onto which to load the texture.
[in,out]	vkTexture	pointer to a ktxVulkanTexture structure into which the function writes information about the created VkImage.
[in]	tiling	type of tiling to use in the destination image on the Vulkan device.
[in]	usageFlags	a set of VkImageUsageFlags bits indicating the intended usage of the destination image.
[in]	finalLayout	a VkImageLayout value indicating the desired final layout of the created image.
[in]	subAllocatorCallbacks	pointer to a set of suballocator callbacks that wrap around suballocator calls: alloc, bindbuffer, bindimage, map, unmap and free. They use a uint64_t stored in the `allocationId` field of the structure pointed at by vkTexture to reference allocated page(s).

Returns: KTX_SUCCESS on success, other KTX_* enum values on error.

Exceptions

KTX_INVALID_VALUE	An incomplete set of callbacks are provided in subAllocatorCallbacks.
KTX_INVALID_VALUE	`This`, `vdi` or `vkTexture` is `NULL`.
KTX_INVALID_OPERATION	The ktxTexture contains neither images nor an active stream from which to read them.
KTX_INVALID_OPERATION	The combination of the ktxTexture's format, `tiling` and `usageFlags` is not supported by the physical device.
KTX_INVALID_OPERATION	Requested mipmap generation is not supported by the physical device for the combination of the ktxTexture's format and `tiling`.
KTX_INVALID_OPERATION	Number of mip levels or array layers exceeds the maximums supported for the ktxTexture's format and `tiling`.
KTX_OUT_OF_MEMORY	Sufficient memory could not be allocated on either the CPU or the Vulkan device.
KTX_UNSUPPORTED_FEATURE	Attempting to sparsely bind KTX textures for the time being will report this error.

◆ ktxVulkanDeviceInfo_Construct()

KTX_error_code ktxVulkanDeviceInfo_Construct	(	ktxVulkanDeviceInfo *	This,
		VkPhysicalDevice	physicalDevice,
		VkDevice	device,
		VkQueue	queue,
		VkCommandPool	cmdPool,
		const VkAllocationCallbacks *	pAllocator )

Construct a ktxVulkanDeviceInfo object.

Records the device information, allocates a command buffer that will be used to transfer image data to the Vulkan device and retrieves the physical device memory properties for ease of use when allocating device memory for the images.

If VK_IMAGE_TILING_OPTIMAL will be passed to ktxTexture_VkUploadEx(), the family of the queue parameter must support transfers. This is true if any of VK_QUEUE_GRAPHICS_BIT, VK_QUEUE_COMPUTE_BIT or VK_QUEUE_TRANSFER_BIT is set in the queueFlags property of the queue's VkQueueFamilyProperties. If protected memory is being used, i.e queueFlags has the VK_QUEUE_PROTECTED_BIT set, then VK_IMAGE_TILING_OPTIMAL must be passed to ktxTexture_VkUploadEx().

VkImages created in ktxTexture_VkUploadEx() will have VK_SHARING_MODE_EXCLUSIVE set. Thus the resulting image will be usable only with queues of the same family as queue.

Pass a valid ktxVulkanDeviceInfo* to any Vulkan KTX image loading function to provide it with the information.

Returns: KTX_SUCCESS on success, other KTX_* enum values on error.

Exceptions

KTX_NOT_FOUND	A dynamically loaded Vulkan function required by the loader was not found.
KTX_OUT_OF_MEMORY	A command buffer could not be allocated.

See also: ktxVulkanDeviceInfo_Destruct()

Parameters

This	pointer to the ktxVulkanDeviceInfo object to initialize.
physicalDevice	handle of the Vulkan physical device.
device	handle of the Vulkan logical device.
queue	handle of the Vulkan queue.
cmdPool	handle of the Vulkan command pool.
pAllocator	pointer to the allocator to use for the image memory. If NULL, the default allocator will be used.

◆ ktxVulkanDeviceInfo_ConstructEx()

KTX_error_code ktxVulkanDeviceInfo_ConstructEx	(	ktxVulkanDeviceInfo *	This,
		VkInstance	instance,
		VkPhysicalDevice	physicalDevice,
		VkDevice	device,
		VkQueue	queue,
		VkCommandPool	cmdPool,
		const VkAllocationCallbacks *	pAllocator,
		const ktxVulkanFunctions *	pFunctions )

Construct a ktxVulkanDeviceInfo object.

Records the device information, allocates a command buffer that will be used to transfer image data to the Vulkan device and retrieves the physical device memory properties for ease of use when allocating device memory for the images.

If VK_IMAGE_TILING_OPTIMAL will be passed to ktxTexture_VkUploadEx(), the family of the queue parameter must support transfers. This is true if any of VK_QUEUE_GRAPHICS_BIT, VK_QUEUE_COMPUTE_BIT or VK_QUEUE_TRANSFER_BIT is set in the queueFlags property of the queue's VkQueueFamilyProperties.

VkImages created in ktxTexture_VkUploadEx() will have VK_SHARING_MODE_EXCLUSIVE set. Thus the resulting image will be usable only with queues of the same family as queue.

Pass a valid ktxVulkanDeviceInfo* to any Vulkan KTX image loading function to provide it with the information.

Returns: KTX_SUCCESS on success, other KTX_* enum values on error.

Exceptions

KTX_NOT_FOUND	A dynamically loaded Vulkan function required by the loader was not found.
KTX_OUT_OF_MEMORY	A command buffer could not be allocated.

cmdPool	handle of the Vulkan command pool.
pAllocator	pointer to the allocator to use for the image memory. If NULL, the default allocator will be used.
instance	handle of the Vulkan instance. If `VK_NULL_HANDLE`, which is not recommended, the function will attempt to initialize the instance-level functions via the platform's standard dynamic library symbol loading mechanisms.
pFunctions	pointer to the struct of functions to use for vulkan operations. Can be NULL in which case the function will retrieve the proc addresses itself.
