Member Function Documentation

void GEO_PointTreeGAOffset::build	(	const GEO_Detail *	gdp,
		const GA_PointGroup *	ptgroup = `NULL`,
		bool	enable_multithreading = `true`
	)

Rebuilds the PointTree with the given detail and point group. If ptgroup is NULL, then all points are used. It will make its own internal vector3 array of the points and original indices.

void GEO_PointTreeGAOffset::build	(	const GEO_Detail *	gdp,
		const GA_PointGroup *	ptgroup,
		const char *	attrib,
