# VkDisplacementMicromapFormatNV(3) Manual Page

## Name

VkDisplacementMicromapFormatNV - Format enum for displacement micromaps

Loading… please wait.

## C Specification

Formats which can be set in VkMicromapUsageEXT::`format` and VkMicromapTriangleEXT::`format` for micromap builds, are:

    // Provided by VK_NV_displacement_micromap
    typedef enum VkDisplacementMicromapFormatNV {
        VK_DISPLACEMENT_MICROMAP_FORMAT_64_TRIANGLES_64_BYTES_NV = 1,
        VK_DISPLACEMENT_MICROMAP_FORMAT_256_TRIANGLES_128_BYTES_NV = 2,
        VK_DISPLACEMENT_MICROMAP_FORMAT_1024_TRIANGLES_128_BYTES_NV = 3,
    } VkDisplacementMicromapFormatNV;

## Description

- `VK_DISPLACEMENT_MICROMAP_FORMAT_64_TRIANGLES_64_BYTES_NV` specifies that the given micromap format encodes 64 micro-triangles worth of displacements in 64 bytes as described in Displacement Micromap Encoding.

- `VK_DISPLACEMENT_MICROMAP_FORMAT_256_TRIANGLES_128_BYTES_NV` specifies that the given micromap format encodes 256 micro-triangles worth of displacements in 128 bytes as described in Displacement Micromap Encoding.

- `VK_DISPLACEMENT_MICROMAP_FORMAT_1024_TRIANGLES_128_BYTES_NV` specifies that the given micromap format encodes 1024 micro-triangles worth of displacements in 128 bytes as described in Displacement Micromap Encoding.

Note | For compactness, these values are stored as 16-bit in some structures.
