inlinestatic

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.
PROctree	pointer to the PROctree structure.
listv	pointer to the volumic ball of the point.
ilistv	size of the volumic ball.
lists	pointer to the surfacic ball of the point.
ilists	size of the surfacic ball.
improve	force the new minimum element quality to be greater or equal than 1.02 of the old minimum element quality.
edgTag	MG_REF, MG_NOM or MG_GEO depending on type of edge on which we move.

Returns: 0 if fail, 1 if success.

Remarks: we don't check if we break the hausdorff criterion.

Move boundary reference, ridge or non-manifold point, whose volumic and surfacic balls are passed.

Todo:: Factorization of this function with the iso one.

Step 0: Compute if the edge is a simple ridge to know if we have to compute a second normal at point

Step 1: Travel surfacic ball and recover the two ending points of curve (that will be stored in ip1 and ip2)

Step 2: At this point, we get the point extremities of the curve passing through ip0 : ip1, ip2, along with support tets it1,it2, the surface faces iface1,iface2, and the associated edges ie1,ie2. Computation of displacement along curve and checks

a. Changes needed for choice of time step : see manuscript notes

b. Check sense of displacement, compute support of the associated edge and features of the new position

Metric interpolation

Check whether proposed move is admissible under consideration of distances

For each surfacic triangle build a virtual displaced triangle for check purposes :

check the new triangle qualities;
check normal deviation with the adjacent through the edge facing ip0 and the previous one

d. Check whether all volumes remain positive with new position of the point and update coor, normals, tangents and qualities if move is accepted.

◆ MMG5_movbdyregpt_ani()

int MMG5_movbdyregpt_ani	(	MMG5_pMesh	mesh,

PROctree	pointer to the PROctree structure.
listv	pointer to the volumic ball of the point.
ilistv	size of the volumic ball.

improve	force the new minimum element quality to be greater or equal than 1.02 of the old minimum element quality.

Returns: 0 if we can't move the point, 1 if we can, -1 if we fail.

Remarks: we don't check if we break the hausdorff criterion.; the metric is not interpolated at the new position.

Move boundary regular point, whose volumic and surfacic balls are passed.

Step 1 : rotation matrix that sends normal n to the third coordinate vector of R^3

Step 2 : rotation of the oriented surfacic ball with r : lispoi[k] is the common edge between faces lists[k-1] and lists[k]

Step 3 : Compute gradient towards optimal position = centre of mass of the ball, projected to tangent plane

Step 4 : locate new point in the ball, and compute its barycentric coordinates

Step 5 : come back to original problem, compute patch in triangle iel and check that geometric approx has not been degraded too much
