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 indicates 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 indicates 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 indicates 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.
