Meshlet

Usage

These structures are used with the ComputeMeshlets and ComputeCullData functions.

Meshlet

struct Meshlet
{
    uint32_t VertCount;
    uint32_t VertOffset;
    uint32_t PrimCount;
    uint32_t PrimOffset;
};

MeshletTriangle

Encodes a triangle in a 30-bit structure that can be packed into a uint32_t DWORD.

struct MeshletTriangle
{
    uint32_t i0 : 10;
    uint32_t i1 : 10;
    uint32_t i2 : 10;
};

Constants

The default values are MESHLET_DEFAULT_MAX_VERTS (128) and MESHLET_DEFAULT_MAX_PRIMS (128). The meshlet sizes can range from MESHLET_MINIMUM_SIZE (32) to MESHLET_MAXIMUM_SIZE (256).
