UPARAM(DisplayName)

Description

Compute the barycentric coordinates (A,B,C) of the Point relative to the specified TriangleID of the TargetMesh. The properties of barycentric coordinates are such that A,B,C are all positive, A+B+C=1.0, and A*Vertex1 + B*Vertex2 + C*Vertex3 = Point. So, the barycentric coordinates can be used to smoothly interpolate/blend any other per-triangle-vertex quantities. The Point must lie in the plane of the Triangle, otherwise the coordinates are somewhat meaningless (but clamped to 0-1 range to avoid catastrophic errors) The Positions of the Triangle Vertices are also returned for convenience (similar to GetTrianglePositions)

true if the TargetMesh has the Vertex Colors attribute enabled

UPARAM(DisplayName)

Description

For the specified TriangleID of the TargetMesh, get the Vertex Colors at each vertex of the Triangle. These Colors will be taken from the Vertex Color Attribute, ie they will potentially be split-colors.

Parameters

Name Remarks
bTriHasValidVertexColors will be returned true if TriangleID exists in TargetMesh and has Vertex Colors set

UPARAM(DisplayName)

Description

Compute the interpolated Vertex Color (A*Color1 + B*Color2 + C*Color3), where (A,B,C)=BarycentricCoords and the Colors are taken from the specified TriangleID in the Vertex Color layer of the TargetMesh.
