VKDESCRIPTORTYPESAMPLER

VKDESCRIPTORTYPE is a data type used in the Vulkan API, a low-level 3D graphics and computing API from the Khronos Group. It is a 32-bit unsigned integer that serves as a handle to various Vulkan objects, such as buffers, images, and pipelines. The type is defined in the Vulkan header file as follows:

typedef uint32_t VKDESCRIPTORTYPE;

The VKDESCRIPTORTYPE is used in conjunction with other Vulkan structures to describe the type of descriptor being used. For example, the VkDescriptorSetLayoutBinding structure includes a VKDESCRIPTORTYPE member to specify the type of descriptor that will be bound to the descriptor set.

The VKDESCRIPTORTYPE is an enumeration, and its values are defined in the Vulkan specification. Some of the common values include:

VK_DESCRIPTOR_TYPE_SAMPLER: A sampler descriptor.

VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER: A combined image sampler descriptor.

VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE: A sampled image descriptor.

VK_DESCRIPTOR_TYPE_STORAGE_IMAGE: A storage image descriptor.

VK_DESCRIPTOR_TYPE_UNIFORM_TEXEL_BUFFER: A uniform texel buffer descriptor.

VK_DESCRIPTOR_TYPE_STORAGE_TEXEL_BUFFER: A storage texel buffer descriptor.

VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER: A uniform buffer descriptor.

VK_DESCRIPTOR_TYPE_STORAGE_BUFFER: A storage buffer descriptor.

VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC: A dynamic uniform buffer descriptor.

VK_DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC: A dynamic storage buffer descriptor.

VK_DESCRIPTOR_TYPE_INPUT_ATTACHMENT: An input attachment descriptor.

The VKDESCRIPTORTYPE is an important part of the Vulkan API, as it allows developers to specify the type of descriptor they want to use in their applications. This information is then used by the Vulkan implementation to allocate the appropriate resources and perform the necessary operations.
