C Specification

Possible values of vkCmdBindIndexBuffer::indexType, specifying the size of indices, are:

// Provided by VK_VERSION_1_0
typedef enum VkIndexType {
    VK_INDEX_TYPE_UINT16 = 0,
    VK_INDEX_TYPE_UINT32 = 1,
  // Provided by VK_KHR_ray_tracing
    VK_INDEX_TYPE_NONE_KHR = 1000165000,
  // Provided by VK_EXT_index_type_uint8
    VK_INDEX_TYPE_UINT8_EXT = 1000265000,
  // Provided by VK_NV_ray_tracing
    VK_INDEX_TYPE_NONE_NV = VK_INDEX_TYPE_NONE_KHR,
} VkIndexType;

Description

  • VK_INDEX_TYPE_UINT16 specifies that indices are 16-bit unsigned integer values.

  • VK_INDEX_TYPE_UINT32 specifies that indices are 32-bit unsigned integer values.

  • VK_INDEX_TYPE_NONE_KHR specifies that no indices are provided.

  • VK_INDEX_TYPE_UINT8_EXT specifies that indices are 8-bit unsigned integer values.
