関数詳解

MG_DLL_DECLR void build_networks	(	const MGFSurface &	surf,
		const MGPvector< MGCurve > &	pcurves,
		MGPvector< MGLoop > &	networks
	)

Build networks of surf, given parameter curves vector.

引数

surf	The objective surface
pcurves	(u,v) 2D parameter curves of surf.
networks	Built networks

MG_DLL_DECLR MGPosition MGClosest_to_curves	(	const MGPosition &	uv,
		const MGPvector< MGCurve > &	curves
	)

Obtain the closest point from point uv to vector of curves. MGClosest_to_curves does not change wc_zero, and so calling program of MGClosest_to_curves should change it if necessary.

引数

uv	Point.
curves	vector of curves.

void MG_DLL_DECLR set_up_shell_shade	(	const MGShell &	shell,
		MGDrawParam &	para,
		MGPvector< MGLBRep > &	boudaries,
		std::vector< std::vector< SHLL_COM_EDGES > > &	polylines
	)

Set up common edges world coordinate line data in polylines. polylines[i] is std::vector<SHLL_COM_EDGES> for face(i) for i=0,...,number_of_faces()-1.

引数

shell	Target shell
para	input tessellation parameter. When para.maximum_edge_length_tess()<=0. is input, maximum_edge_length is computed and set in para.
boudaries	Container of the boundary data. Polylined boundaries will be held in boundaries.
polylines	polylines[i] holds boundary data of shell.face(i)'s loops polylined boundaries data.

MG_DLL_DECLR std::auto_ptr<MGLoop> trim_out_subloop	(	const MGLEPoint &	ts,
		const MGLEPoint &	te
	)

Get the clone of ts.loop()(==te.loop()), and trim th loop from ts to te. Function's return value is the trimmed loop.
