Function Documentation

MMG5_mmgsBezierCP()

int MMG5_mmgsBezierCP	(	MMG5_pMesh	mesh,
		MMG5_Tria *	pt,
		MMG5_pBezier	pb,
		int8_t	ori
	)

Parameters

mesh	pointer to the mesh structure.
pt	pointer to the triangle structure.
pb	pointer to the computed Bezier structure.
ori	triangle orientation (unused but here for compatibility with the MMG5_bezierCP interface).

Returns

1.

Compute Bezier control points on triangle pt (cf. [4]).

Todo:

merge with the MMG5_mmg3dBezierCP function and remove the pointer toward this functions.

MMGS_bezierInt()

int MMGS_bezierInt	(	MMG5_pBezier	pb,
		double	uv[2],
		double	o[3],
		double	no[3],
		double	to[3]
	)

Parameters

pb	pointer to the Bezier structure.
uv	coordinates of the point in the parametric space.
o	computed coordinates of the point in the real space.
no	computed normal.
to	computed tangent.

Returns

1.

Compute o, no and to at \((u,v)\) in Bezier patch.
