◆ MMG3D_adpcoledg()

int MMG3D_adpcoledg	(	MMG5_pMesh	mesh,
		MMG5_pSol	met,
		MMG3D_pPROctree *	PROctree,
		MMG5_int	k,
		int8_t	imin,
		double	lmin,
		MMG5_int *	nc
	)

Parameters

mesh	pointer to the mesh structure.
met	pointer to the metric structure.
PROctree	pointer to the PROctree structure.
k	index of tetra in which we work.
imin	index in k of edge that we consider for collapse.
lmin	length of edge imin.
nc	pointer to count of collapses (has to be updated)

Returns: -1 for strong failure.; 0 if edge cannot be collapsed and if we want to pass to next loop step (next element or next tetra edge); 2 if edge has been collapsed.; 3 if nothing has been done (no error but no collapse either).

Try to collapse edge imin it too small.

◆ MMG3D_analys()

int MMG3D_analys ( MMG5_pMesh mesh )

Parameters

mesh	pointer to mesh

Returns: 1 if successful, 0 if fail

preprocessing stage: mesh analysis.

At the end of this function:

triangles have been deleted and stored in xtetra;
Boundary point have been analyzed and associated to xpoints (if needed). If computed tangent is stored in ppt->n and normals in pxp->n1 and pxp->n2. Following list summerizes computed (and not computed) data depending on point type:
- Corner point (MG_CRN): no computation (and no xpoint);
- Required points have different treatment depending if they are along a 'regular' surf point, along an internal or external non-manifold edge, along a non connex mesh part(so they may have a xpoint, a tangent and a normal or not) but their normal is not used during remeshing. See comments in MMG3D_nmgeom
- Reference point (MG_REF): xpoint, tangent, 1 normal;
- Ridge point (MG_GEO): xp, tangent,2 normals;
- Non-manifold point (MG_NOM): xp, tangent, no normal if internal, 1 normal if external
- Open boundary points (MG_OPNBDY) are treated as nm points.

Returns: 0 if fail (one of curve extremity is not found), 1 if success.

Search the two ending points of curve passing through ip0 in the surfacic ball of ip0.

Travel surfacic ball and recover the two ending points of curve (that will be stored in ip1 and ip2): ball is travelled from beginning in one direction until meeting the curve edge, then, starting from the end, in the other direction until meeting the second curve edge.

a. Travel surface edges in one sense to get the first featured edge. Triangles of the surface are successively processed and the tag of the edge between current tria and previous one is tested (so each edge is checked only once). Ball processing stops at first featured edge crossed.

b. Now travel surface edges in the reverse sense so as to get the second curve. Again, we test the tag of the edge at interface of current triangle and previous one and we stop ball pocessing when the second featured edge has been found. This edge is necessarly different from the one previously found.

Enforces mesh gradation by truncating metric field.

On singular (CRN, REQ, NOM) points, the metric on P is isotropic (as in MMG5_defmetsin) and should remain isotropic.
On non-singular ridge points, the metric on P should remain aligned with the ridge directions (thus it is not possible to apply metric intersection, sizes are truncated instead).
On regular boundary points, the metric can be anisotropic on the tangent plane, but it should remain aligned to the normal direction (thus, intersection is used only in the tangent plane and sizes are truncated in the normal direction).
On interior volume points, 3D metric intersection can be used.

Following list summerizes computed data depending on point type:

Non-manifold external point along connex mesh part (MG_NOM): xp, tangent, normal n1, nnor=0
Non-manifold external point along edge or point connected mesh part (MG_NOM): no xp,no tangent,no normal,nnor=0
Non-manifold not required internal point (MG_NOM+MG_REQ): xp, tangent, no normal, nnor=1.
Non-manifold required internal point (MG_NOM+MG_REQ): no xp, no tangent, no normal, nnor=1.
Non-manifold open-boundary (MG_OPNBDY) edges are treated like others:
- if we are along a "truly" open boundary, it is an internal nm edge so we don't have any normal;
- if the edge is marked as open while being only non-manifold, we may compute a normal (along an external boundary) or not (along an internal one).

Merge tags and references of edges that will merge due to the collapse (the shell of each edge is travelled so each xtetra of the shell is updated). Note that it can't be done in the previous loop because the mesh would be corrupted if we stop the collapse. It can't neither be done in the next loop because we start to delete the elements of the shell.

It is due to the fact that regular boundary edges are not always marked as boundary inside a xtetra and tetra with boundary edges but no boundary faces are not always associated to an xtetra (moreover, for edges not belonging to a face inside the xtetra, the tag is not always up to date).

Remarks

prior to commit f57b861966: we were comparing absolute values of normals projection (guessing that normals can be bad oriented). In this case, we can choose the wrong normal (normal at point related to other portion of surface) when the ridge angle is almost closed (smallest than 90°) because projection of normal at first triangle and normal at second triangle (or normal at point related to second surface) tends to -1;
the following assert on the positivity of at least one of the projections may fail but I think that it is not a normal behaviour: it means that the surface approximation has degenerated. See issue #167

Following list summerizes computed (and not computed) data depending on point type:

Corner point (MG_CRN): nothing (and no xpoint);
Reference point (MG_REF): xp, tangent (ppt->n), 1 normal (pxp->n1);
Ridge point (MG_GEO): xp, tangent,2 normals (pxp->n1 and n2);
Non-manifold point (MG_NOM) are not filled here but in nmgeom function
Open boundary points (MG_OPNBDY) are non-manifold so they are filled in nmgeom too.
Required points are analyzed using their other flags (so they may have an xpoint and a normal) but their normal is not used during remeshing.

Normals at regular boundary points can be provided by users but are ignored along featured edges.

recomputation of normals only if mesh->xpoint has been freed

Step 1: identify boundary points

input normals are ignored along all type of featured edges (ref, geo, nom) but it is possible to implement their taking into account along non-ridges reference edges and external non-manifold ones.

Step 2: Allocate memory to store normals for boundary points

Step 3: compute normals + tangents

At C1 point

Remarks: : as all triangles are mesh boundaries, we do not need to mark their adges as MG_BDY so the MG_BDY tag may be used inside geometrical triangles (external non-parallel, or internal parallel) to tag edges on the intersection with purely parallel (non-geometrical) triangles. The MG_PARBDYBDY tag is also added, as it does not have a supporting triangle to inherit this tag from.; REQ, NOSURF, etc... tags are added only inside xtetra.; In openbdy mode, all non-manifold edges are marked as opnbdy.

int MMG5_setdhd ( MMG5_pMesh mesh )

check for ridges: dihedral angle

Step 1: check input ridges provided by the user to remove those ones between triangles belonging to the same plane. This step has to be done prior the next one because we want to remove the MG_GEO tag transfered from ridges that we delete toward vertices by MMG5_setadj but we want to preserve the MG_GEO tags at vertices of ridges that will be added by the next step.

Step 2: check ref and angle with neighbour to update ref tags and ridge ones

Parameters

mesh	pointer to the mesh structure.

Returns: 1 if success, 0 if fail. Seek the non-required non-manifold points and try to analyse whether they are corner or required.

Remarks: We don't know how to travel through the shell of a non-manifold point by triangle adjacency. Thus the work done here can't be performed in the MMG5_singul function.; a temporary array tmp is used instead of the tmp field of the points to not break the ParMmg distributed analysis in which this field is used to store the global numbering of nodes.

Seek the non-required non-manifold points and try to analyse whether they are corner or required.

Step 1: count the number or feature edges passing through each points

Step 2: add suitable point tags depending on the counted feature edges

Table that associates to each (even) permutation of the 4 vertices of a tetrahedron the corresponding permutation of its edges.
Labels : 0 : [0,1,2,3] 1 : [0,2,3,1] 2 : [0,3,1,2] 3 : [1,0,3,2] 4 : [1,2,0,3] 5 : [1,3,2,0] 6 : [2,0,1,3] 7 : [2,1,3,0] 8 : [2,3,0,1] 9 : [3,0,2,1] 10 : [3,1,0,2] 11 : [3,2,1,0] The edge 0 of the config 1 become the edge 1 of the reference config so permedge[1][0]=1 ...
