Constructor & Destructor Documentation

VulkanImageBuffer() [1/2]

Karma::VulkanImageBuffer::VulkanImageBuffer

(

const char *

filename

)

Creates a GPU memory buffer for storing image texture.

Parameters

filename

The path to the file, including filename, containing the image texture

Since

VulkanImageBuffer() [2/2]

Karma::VulkanImageBuffer::VulkanImageBuffer	(	FVulkanDevice *	InDevice,
		const char *	filename )

Creates GPU memory buffer for storing image texture with VulkanRHI support.

Parameters

InDevice	The FVulkanDevice object
filename	The path to the file, including filename, containing the image texture

Member Function Documentation

CreateBuffer()

void Karma::VulkanImageBuffer::CreateBuffer	(	VkDeviceSize	size,
		VkBufferUsageFlags	usage,
		VkMemoryPropertyFlags	properties,
		VkBuffer &	buffer,
		VkDeviceMemory &	bufferMemory )

Creates Vulkan buffer (VKbuffer) for image texture's use and allocates device memory appropriately.

Parameters

size	The size, in bytes, of the buffer to be created
properties	The demanded properties (https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VkBufferUsageFlagBits.html). For instance (VK_BUFFER_USAGE_TRANSFER_SRC_BIT, VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT | VK_MEMORY_PROPERTY_HOST_COHERENT_BIT)
