FMeshWeights::CotanCentroidSafe

Compute cotan-weighted centroid of a vertex one-ring, with some weight analysis/clamping to avoid vertices getting "stuck" in explicit integration/iterations.

Syntax

static FVector3d CotanCentroidSafe
(
    const FDynamicMesh3 & Mesh,
    int32 VertexIndex,
    TFunctionRef< FVector3d)> VertexPositionFunc,
    double DegenerateTol,
    bool * bFailedToUniform
)

Remarks

Compute cotan-weighted centroid of a vertex one-ring, with some weight analysis/clamping to avoid vertices getting "stuck" in explicit integration/iterations. If failure is detected, Uniform centroid is returned, which does cause some tangential flow

Parameters

Parameter	Description
DegenerateTol	if any weights are larger than this value, return uniform weights instead. Should be > 1.
bFailedToUniform	will be set to true if non-null and result was clamped
