Function Documentation

◆ MMG5_interp_iso()

int MMG5_interp_iso	(	double *	ma,
		double *	mb,
		double *	mp,
		double	t
	)

Parameters

ma	pointer on a metric
mb	pointer on a metric
mp	pointer on the computed interpolated metric
t	interpolation parameter (comprise between 0 and 1)

Linear interpolation of isotropic sizemap along an edge

Here is the caller graph for this function:

◆ MMG5_interpreg_ani()

int MMG5_interpreg_ani	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_pTria	pt,
		int8_t	i,
		double	s,
		double	mr[6]
	)

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.
pt	pointer to the triangle structure.
i	edge of the triangle pt
s	interpolated parameter (comprise between 0 and 1)
mr	computed interpolated metric

Returns: 0 if fail, 1 otherwise.

Metric interpolation between points p1 and p2, in tria pt at parameter 0 <= s <= 1 from p1 result is stored in mr. edge p1p2 must not be a ridge

◆ MMG5_intridmet()

int MMG5_intridmet	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG5_int	ip1,
		MMG5_int	ip2,
		double	s,
		double	v[3],
		double	mr[6]
	)

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.
ip1	global index of ridge extremity.
ip2	global index of ridge extremity.
s	interpolation parameter (between 0 and 1).
v	normal at the point at which we want to compute the metric.
mr	computed anisotropic size.

Returns: 1 if success, 0 otherwise.

Anisotropic metric interpolation between two points \(p_1\) and \(p_2\) such that \(edge_0 = (p_1p_2)\) is ridge. v is a direction vector, aimed at pointing towards direction of n1 at interpolated point.

◆ MMG5_mmgIntmet33_ani()

int MMG5_mmgIntmet33_ani	(	double *	m,
		double *	n,
		double *	mr,
		double	s
	)

Parameters

m	input metric.
n	input metric.
mr	computed output metric.
s	parameter coordinate for the interpolation of metrics m and n.

Returns: 0 if fail, 1 otherwise.

Compute the interpolated \((3 x 3)\) metric from metrics m and n, at parameter s : \( mr = (1-s)*m +s*n \), both metrics being expressed in the simultaneous reduction basis: linear interpolation of sizes.
