Class GeoMesh2
- Namespace
- GeometryHelper.Meshing
- Assembly
- GeometryHelper.dll
A closed shape of the plane broken into faces that share their corners: triangles, the cells of a grid, strips or convex pieces, as MeshKind says.
Every face is a simple polygon with no hole, running counter-clockwise, given by the indexes of its corners in Vertices. The faces lie within the shape's material and cover it without overlapping, holes left open, and meet edge to edge: a corner of one face standing on the side of another is a corner of that one too, so two faces side by side share the same edge, run the two ways round. Such a corner may leave a face with three corners in a row. The mesh is immutable.

Properties
- Area
Gets the area the faces cover together: the shape's material, less the joints of a grid.
- FaceCount
Gets how many faces there are.
- Kind
Gets the kind of faces the mesh was made of.
- VertexCount
Gets how many places the faces share.
- Vertices
Gets the places the faces share, each once.
Methods
- GetAdjacentFaces(int)
Gets the faces that share an edge with a face.
- GetBoundaryEdges()
Gets the edges only one face has: the shape's boundary and the rims of its holes, and for a grid with joints the outline of every cell.
- GetEdges()
Gets every edge of the mesh once, whether one face has it or two.
- GetFace(int)
Gets a face as a polygon, counter-clockwise, with every corner it has, three in a row among them.
- GetFaceIndices(int)
Gets the indexes in Vertices of the corners of a face, counter-clockwise.
- GetFaces()
Gets every face as a polygon, counter-clockwise, in the order of their indexes.
- IsWhole(int)
Gets whether a face is a whole cell of a grid, which neither the boundary nor a hole cuts by more than the point tolerance.
- RotateBy(double, GeoPoint2)
Turns the mesh about a point.
- ToString()
Describes the mesh.
- ToTriangles()
Breaks every face into triangles on its own corners, counter-clockwise.
- TransformBy(GeoTransform2)
Transforms the mesh.
- Translate(GeoVector2)
Moves the mesh by a vector.
