Function Documentation

GEO_API void GEOgetInterpolationWeights	(	const GEO_Detail *	detail,
		GA_Offset	primoff,
		UT_Array< GA_Offset > &	offsets,
		UT_FloatArray &	weights,
		const UT_Vector3 &	uvw,
		bool	is_point_offsets = false
	)

Fill the offsets and weights arrays with the vertex/point offsets and their corresponding interpolation weights for the given primitive parametric space coordinate uvw, for the specified primitive.

This acts like GEO_Primitive::computeInteriorPointWeights(), except that it avoids hardening the primitive list if the primitive is a polygon or tetrahedron, and if is_point_offsets is true, it will convert the offsets to point offsets, instead of staying with vertex offsets.

template<typename INT >

void geoInterpolateAttributes	(	const GEO_Detail *	source,
		const GA_AttributeRefMap &	attribmap,
		const GA_Range &	destrange,
		const GA_ROHandleT< INT > &	primnumattrib,
		const GA_ROHandleV3 &	primuvwattrib
	)

Interpoates attributes based on primitive index and (u,v,w) INT must be int32 or int64.

template<typename INT >

void geoInterpolateAttributes	(	const GEO_Detail *	source,
		const GA_AttributeRefMap &	attribmap,
		const GA_Range &	destrange,
		const GA_ROHandleT< INT > &	primnumattrib,
		const GA_ROHandleV3 &	primuvwattrib,
		GA_AttributeOwner	computenumbersof,
		GA_Attribute *	computeindexattrib,
		GA_Attribute *	computeweightattrib
	)

Interpoates attributes based on primitive number and (u,v,w), and fills in computeindexattrib and computeweightattrib with the point or vertex indices and weights that produced the interpolation. computenumbersof determines whether computeindexattrib receives point or vertex indices. computeindexattrib and computeweightattrib must implement GA_AIFNumericArray. INT must be int32 or int64.

GEO_API void geoInterpolateAttributes	(	const GEO_Detail *	source,
		const GA_AttributeRefMap &	attribmap,
		const GA_Range &	destrange,
		GA_AttributeOwner	indexowner,
		const GA_Attribute *	indexattrib,
		const GA_Attribute *	weightattrib
	)

Interpoates attributes based on arrays of indices and weights specified in indexattrib and weightattrib. indexowner specifies whether the source indices are for points, vertices, or primitives. indexattrib and weightattrib must implement GA_AIFNumericArray.
