Function Documentation

template<typename T >

GEO_API void GEOevaluateInteriorPoint	(	const GEO_Detail *	gdp,
		GA_Offset	primoff,
		const GA_ROHandleT< T > &	h,
		const UT_Vector3 &	uvw,
		T *	buf,
		int	size
	)

Evaluate a GA_ROHandle based on the uvw position, can either evaluate into a buffer or return the result.

Uses GEOgetInterpolationWeights in order to interpolate vertex and point attributes.

GEO_API void GEOevaluateInteriorPoint	(	const GEO_Detail *	gdp,
		GA_Offset	primoff,
		const GA_ROHandleS &	h,
		const UT_Vector3 &	uvw,
		UT_StringHolder *	buf,
		int	size
	)

Evaluate a GA_ROHandle based on the uvw position, can either evaluate into a buffer or return the result.

Uses GEOgetInterpolationWeights in order to interpolate vertex and point attributes.

template<typename T >

SYS_FORCE_INLINE GEO_API T GEOevaluateInteriorPoint	(	const GEO_Detail *	gdp,
		GA_Offset	primoff,
		const GA_ROHandleT< T > &	h,
		const UT_Vector3 &	uvw
	)

Evaluate a GA_ROHandle based on the uvw position, can either evaluate into a buffer or return the result.

Uses GEOgetInterpolationWeights in order to interpolate vertex and point attributes.

Definition at line 323 of file GEO_Interpolate.h.

SYS_FORCE_INLINE GEO_API UT_StringHolder GEOevaluateInteriorPoint	(	const GEO_Detail *	gdp,
		GA_Offset	primoff,
		const GA_ROHandleS &	h,
		const UT_Vector3 &	uvw
	)

Evaluate a GA_ROHandle based on the uvw position, can either evaluate into a buffer or return the result.

Uses GEOgetInterpolationWeights in order to interpolate vertex and point attributes.

Definition at line 336 of file GEO_Interpolate.h.

GEO_API void GEOgetInterpolationWeights	(	const GEO_Detail *	detail,
		GA_Offset	primoff,
		UT_Array< GA_Offset > &	offsets,
		UT_Array< float > &	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,
		const GEO_InterpolationOptions &	options
	)

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,
		const GEO_InterpolationOptions &	options
	)

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,
		const GEO_InterpolationOptions &	options
	)

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.
