VkMicromapTriangleKHR(3)

# VkMicromapTriangleKHR(3) Manual Page

## Name

VkMicromapTriangleKHR - Structure specifying the micromap format and data for a triangle

## C Specification

The `VkMicromapTriangleKHR` structure is defined as:

    // Provided by VK_KHR_opacity_micromap
    typedef struct VkMicromapTriangleKHR {
        uint32_t    dataOffset;
        uint16_t    subdivisionLevel;
        uint16_t    format;
    } VkMicromapTriangleKHR;

    // Provided by VK_EXT_opacity_micromap
    // Equivalent to VkMicromapTriangleKHR
    typedef VkMicromapTriangleKHR 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

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