C Specification

The VkMicromapTriangleEXT structure is defined as:

// Provided by VK_EXT_opacity_micromap
typedef struct VkMicromapTriangleEXT {
    uint32_t    dataOffset;
    uint16_t    subdivisionLevel;
    uint16_t    format;
} VkMicromapTriangleEXT;

Members

  • dataOffset is the offset in bytes of the start of the data for this triangle. This is a byte aligned value.

  • subdivisionLevel is the subdivision level of this triangle

  • format is the format of this triangle

Description

Valid Usage
  • VUID-VkMicromapTriangleEXT-format-07522
    If the VkMicromapTypeEXT of the micromap is VK_MICROMAP_TYPE_OPACITY_MICROMAP_EXT then format must be VK_OPACITY_MICROMAP_FORMAT_2_STATE_EXT or VK_OPACITY_MICROMAP_FORMAT_4_STATE_EXT

  • VUID-VkMicromapTriangleEXT-format-07523
    If the VkMicromapTypeEXT of the micromap is VK_MICROMAP_TYPE_OPACITY_MICROMAP_EXT and format is VK_OPACITY_MICROMAP_FORMAT_2_STATE_EXT then subdivisionLevel must be less than or equal to VkPhysicalDeviceOpacityMicromapPropertiesEXT::maxOpacity2StateSubdivisionLevel

  • VUID-VkMicromapTriangleEXT-format-07524
    If the VkMicromapTypeEXT of the micromap is VK_MICROMAP_TYPE_OPACITY_MICROMAP_EXT and format is VK_OPACITY_MICROMAP_FORMAT_4_STATE_EXT then subdivisionLevel must be less than or equal to VkPhysicalDeviceOpacityMicromapPropertiesEXT::maxOpacity4StateSubdivisionLevel

  • VUID-VkMicromapTriangleEXT-format-08708
    If the VkMicromapTypeEXT of the micromap is VK_MICROMAP_TYPE_DISPLACEMENT_MICROMAP_NV then format must be VK_DISPLACEMENT_MICROMAP_FORMAT_64_TRIANGLES_64_BYTES_NV, VK_DISPLACEMENT_MICROMAP_FORMAT_256_TRIANGLES_128_BYTES_NV or VK_DISPLACEMENT_MICROMAP_FORMAT_1024_TRIANGLES_128_BYTES_NV

  • VUID-VkMicromapTriangleEXT-subdivisionLevel-08709
    If the VkMicromapTypeEXT of the micromap is VK_MICROMAP_TYPE_DISPLACEMENT_MICROMAP_NV then subdivisionLevel must be less than or equal to VkPhysicalDeviceDisplacementMicromapPropertiesNV::maxDisplacementMicromapSubdivisionLevel

The format is interpreted based on the type of the micromap using it.
