## Name

VkBuildMicromapFlagBitsEXT - Bitmask specifying additional parameters for micromap builds

Loading… please wait.

## C Specification

Bits which can be set in VkMicromapBuildInfoEXT::`flags` specifying additional parameters for micromap builds, are:

    // Provided by VK_EXT_opacity_micromap
    typedef enum VkBuildMicromapFlagBitsEXT {
        VK_BUILD_MICROMAP_PREFER_FAST_TRACE_BIT_EXT = 0x00000001,
        VK_BUILD_MICROMAP_PREFER_FAST_BUILD_BIT_EXT = 0x00000002,
        VK_BUILD_MICROMAP_ALLOW_COMPACTION_BIT_EXT = 0x00000004,
    } VkBuildMicromapFlagBitsEXT;

## Description

- `VK_BUILD_MICROMAP_PREFER_FAST_TRACE_BIT_EXT` specifies that the given micromap build should prioritize trace performance over build time.

- `VK_BUILD_MICROMAP_PREFER_FAST_BUILD_BIT_EXT` specifies that the given micromap build should prioritize build time over trace performance.
