◆ FindCoincidentFreeBorders()

SMESHUtils_EXPORT void SMESH_MeshAlgos::FindCoincidentFreeBorders ( SMDS_Mesh mesh,
double  tolerance,
CoincidentFreeBorders foundFreeBordes 
)

Returns TFreeBorder's coincident within the given tolerance. If the tolerance <= 0.0 then one tenth of an average size of elements adjacent to free borders being compared is used.

(Implemented in ./SMESH_FreeBorders.cxx)

◆ FindFaceInSet()

const SMDS_MeshElement * SMESH_MeshAlgos::FindFaceInSet ( const SMDS_MeshNode n1,
const SMDS_MeshNode n2,
const TIDSortedElemSet &  elemSet,

int *  i1 = 0,
int *  i2 = 0 
)

◆ GetBarycentricCoords()

void SMESH_MeshAlgos::GetBarycentricCoords ( const gp_XY &  point,
const gp_XY &  t0,
const gp_XY &  t1,
const gp_XY &  t2,
double &  bc0,
double &  bc1 
)

Returns barycentric coordinates of a point within a triangle. A not returned bc2 = 1. - bc0 - bc1. The point lies within the triangle if ( bc0 >= 0 && bc1 >= 0 && bc0+bc1 <= 1 )

◆ GetDistance() [2/4]

double SMESH_MeshAlgos::GetDistance ( const SMDS_MeshElement elem,
const gp_Pnt &  point 
)

Return minimal distance from a point to an element.

Currently we ignore non-planarity and 2nd order of face
