Member Function Documentation

addTriangles() [1/2]

None mrmeshpy.MeshBuilder.addTriangles ( MeshTopology res, std_vector_Id_VertTag vertTriples, FaceBitSet createdFaces = None )

static

adds triangles in the existing topology, auto selecting face ids for them;
vertTriples on output contain the remaining triangles that could not be added into the topology right now, but may be added later when other triangles appear in the mesh

addTriangles() [2/2]

int mrmeshpy.MeshBuilder.addTriangles ( MeshTopology res, Triangulation t, MeshBuilder.BuildSettings settings = ... )

static

adds triangles in the existing topology, given face indecies must be free;
settings.region on output contain the remaining triangles that could not be added into the topology right now, but may be added later when other triangles appear in the mesh
\\return the total number of triangles added in the topology

duplicateNonManifoldVertices()

int mrmeshpy.MeshBuilder.duplicateNonManifoldVertices ( Triangulation t, FaceBitSet region = None, std_vector_MeshBuilder_VertDuplication dups = None, VertId lastValidVert = ... )

static

resolve non-manifold vertices by creating duplicate vertices in the triangulation (which is modified)
`lastValidVert` is needed if `region` or `t` does not contain full mesh, then first duplicated vertex will have `lastValidVert+1` index
return number of duplicated vertices

fromDisjointMeshPieces()

MeshTopology mrmeshpy.MeshBuilder.fromDisjointMeshPieces ( Triangulation t, VertId maxVertId, std_vector_MeshBuilder_MeshPiece pieces, MeshBuilder.BuildSettings settings = ... )

static

construct mesh topology in parallel from given disjoint mesh pieces (which do not have any shared vertex)
and some additional triangles (in settings) that join the pieces

fromFaceSoup()

MeshTopology mrmeshpy.MeshBuilder.fromFaceSoup ( std_vector_Id_VertTag verts, Vector_MeshBuilder_VertSpan_FaceId faces, MeshBuilder.BuildSettings settings = ..., func_bool_from_float progressCb = '{}' )

static

construct mesh topology from face soup, where each face can have arbitrary degree (not only triangles)

fromPointTriples()

Mesh mrmeshpy.MeshBuilder.fromPointTriples ( std_vector_std_array_Vector3_float_3ul posTriples )

static

construct mesh from point triples;
all coinciding points are given the same VertId in the result

fromTriangles()

MeshTopology mrmeshpy.MeshBuilder.fromTriangles ( Triangulation t, MeshBuilder.BuildSettings settings = ..., func_bool_from_float progressCb = '{}' )

static

construct mesh topology from a set of triangles with given ids;
if skippedTris is given then it receives all input triangles not added in the resulting topology

fromTrianglesDuplicatingNonManifoldVertices()

MeshTopology mrmeshpy.MeshBuilder.fromTrianglesDuplicatingNonManifoldVertices ( Triangulation t, std_vector_MeshBuilder_VertDuplication dups = None, MeshBuilder.BuildSettings settings = ... )

static

construct mesh topology from a set of triangles with given ids;
unlike simple fromTriangles() it tries to resolve non-manifold vertices by creating duplicate vertices;
triangulation is modified to introduce duplicates

uniteCloseVertices() [1/2]

int mrmeshpy.MeshBuilder.uniteCloseVertices ( Mesh mesh, float closeDist, bool uniteOnlyBd = True, VertMap optionalVertOldToNew = None )

static

the function finds groups of mesh vertices located closer to each other than \\param closeDist, and unites such vertices in one;
then the mesh is rebuilt from the remaining triangles
\\param optionalVertOldToNew is the mapping of vertices: before -> after
\\param uniteOnlyBd if true then only boundary vertices can be united, all internal vertices (even close ones) will remain
\\return the number of vertices united, 0 means no change in the mesh

uniteCloseVertices() [2/2]

int mrmeshpy.MeshBuilder.uniteCloseVertices ( Mesh mesh, MeshBuilder.UniteCloseParams params = ... )

static

the function finds groups of mesh vertices located closer to each other than \\param params.closeDist, and unites such vertices in one;
then the mesh is rebuilt from the remaining triangles
\\return the number of vertices united, 0 means no change in the mesh
