Syntax

static void GridSample
(
    const FDynamicMesh3 & Mesh,
    int GridResolutionMaxAxis,
    TArray< int32 > & OutSamples
)

Remarks

Choose a more or less evenly-spaced subset of mesh vertices. Conceptually, this function creates a uniform grid with given cell size. (Cell size is given roughly as a percentage of the total mesh bounding box.) Each grid cell can hold up to one vertex. Return the set of representative vertices, maximum one per cell.

Parameters

Parameter	Description
Mesh	Surface mesh whose vertices we want to sample
CellSizeAsPercentOfBounds	Grid cell size expressed as a percentage of the mesh bounding box size
OutSamples	Indices of chosen vertices
