IVertexAttribute Interface

Identifies geometries that can have attributes on their vertices.

Members

	Name	Description
	CalculateNonSimpleVertexAttributes	Extrapolates/interpolates the non-simple vertex attribute values.
	ExtrapolateVertexAttributes	Extrapolates the attribute values at the begining of the geometry up to the fromIndex based on the attribute value interval between the fromIndex and the toIndex.
	InterpolateVertexAttributesBetween	Generate vertex attribute values by linear interpolation for all vertices in the range [start+1, end-1]. (Sets point IDs to 0 rather than interpolating).
	MultiplyVertexAttributes	Scale all vertex attribute values of this type by the specified factor.
	OffsetVertexAttributes	Offset all vertex attribute values of this type by the specified factor.
	TransferAttributes	For each vertex on this geometry, assign the attributes found at the point an equal fraction of the distance along the source geometry (the point need not be an explicit vertex).
	VertexAttributeMax	The maximum vertex attribute value of this type for all vertices in this object.
	VertexAttributeMin	The minimum vertex attribute value of this type for all vertices in this object.
	VertexAttributeSimple	Indicates if there are no 'empty' vertex attribute values of this type for this object.
