C Specification

To get the handle for a combined image sampler, call:

// Provided by VK_NVX_image_view_handle
uint64_t vkGetDeviceCombinedImageSamplerIndexNVX(
    VkDevice                                    device,
    uint64_t                                    imageViewIndex,
    uint64_t                                    samplerIndex);

Parameters

  • device is the logical device that will use the result handle.

  • imageViewIndex is the index within the resource heap.

  • samplerIndex is the index within the sampler heap.

Description

Shaders take imageViewIndex and samplerIndex, and multiply it by VkPhysicalDeviceDescriptorHeapPropertiesEXT::imageDescriptorSize and VkPhysicalDeviceDescriptorHeapPropertiesEXT::samplerDescriptorSize respectively to obtain the descriptor offset in bytes.

Valid Usage (Implicit)

  • VUID-vkGetDeviceCombinedImageSamplerIndexNVX-device-parameter
    device must be a valid VkDevice handle
