GU_API void GUblend	(	GU_Detail *	dest,
		const GU_Detail *	source,
		fpreal	weight,
		const char *	pattern = "*",
		const UT_StringRef &	ptidattr = GA_Names::id,
		const UT_StringRef &	primidattr = GA_Names::name,
		bool	doslerp = true,
		bool	usevforpinterp = false,
		float	timestep = (1/24.0),
		GU_VoxelBlend	dovoxel = GU_VoxelBlend::None,
		GU_Blend::CachedItems *	cached_items = NULL,
		const char *	velname = "vel",
		float	advdt = 1,
		bool	deleteUnmatched = false,
		const char *	unmatchedGroupName = NULL
	)

If deleteUnmatched is true, points that don't have a match to interpolate with are deleted. If deleteUnmatched is false but unmatchedGroupName is given (non-NULL), then these points are instead put into a point group of the specified name. Note that points of volume and VDB primitives are neither deleted nor put into the group.

GU_API void GUblend	(	GU_Detail *	dest,
		const GU_Detail *	gdps[],
		const float *	weights,
		int	size,
		const GA_Group *	group,
		const char *	pattern = "*",
		const UT_StringRef &	ptidattr = GA_Names::id,
		const UT_StringRef &	primidattr = GA_Names::name,
		bool	doslerp = true,
		GU_VoxelBlend	dovoxel = GU_VoxelBlend::None,
		GU_Blend::CachedItems *	cached_items = NULL,
		bool	is_differencing = true,
		bool	dosparse = false,
		float	timestep = (1/24.0),
		const char *	velname = "vel",
		float	advdt = 1,
		fpreal	volweight = 0,
		int	deleteUnmatched = 0,
		const char *	unmatchedGroupName = NULL
	)

If deleteUnmatched is non-zero, points that have fewer than that many interpolation sources are deleted from the output (or put into the specified group if unmatchedGroupName is not NULL). NOTE: Advected volume interpolation is necessarily linear; in that case, volweight is needed to determine which detail to blend with and by how much.

GU_API void GUblendRange	(	GA_Attribute &	attrib0,
		const GA_Attribute &	attrib1,
		const GA_Range &	range0,
		float	weight,
		const UT_Array< GA_Offset > *	mapping
	)

Blend the attribute values for the given range, with an optional mapping to different offsets in the second detail.
