MeshTopologyVertexList

MeshTopologyVertexList class

Provides access to the mesh topology vertices of a mesh. Topology vertices are sets of vertices in the MeshVertexList that can topologically be considered the same vertex.

Derived Classes:

Namespace: Rhino.Geometry.Collections
MeshTopologyVertexList: references

Properties (2)

Count

Gets or sets the number of mesh topology vertices.

Item

Gets or sets the vertex at the given index. Setting a location adjusts all vertices in the mesh's vertex list that are defined by this topological vertex The index must be valid or an IndexOutOfRangeException will be thrown.

Methods (13)

ConnectedEdge(int topologyVertexIndex, int edgeAtVertexIndex)

Gets a particular edge that is connected to a topological vertex.
Call TopologyVertices.SortVertices before this if you are interested in ordered edges.

ConnectedEdges(int topologyVertexIndex)

Gets all edges that are connected to a given vertex.
Call TopologyVertices.SortVertices before this if you are interested in ordered edges.

ConnectedEdgesCount(int topologyVertexIndex)

Gets the count of edges that are connected to a given vertex.

ConnectedFaces(int topologyVertexIndex)

Gets all faces that are connected to a given vertex.

ConnectedTopologyVertices(int topologyVertexIndex, bool sorted)

Gets all topological vertices that are connected to a given vertex.

ConnectedTopologyVertices(int topologyVertexIndex)

Gets all topological vertices that are connected to a given vertex.

GetEnumerator()

Gets an enumerator that yields all topology vertices in this collection.

IndicesFromFace(int faceIndex)

Returns TopologyVertexIndices for a given mesh face index.

IsHidden(int topologyVertexIndex)

Returns True if the topological vertex is hidden. The mesh topology vertex is hidden if and only if all the ON_Mesh vertices it represents is hidden.

MeshVertexIndices(int topologyVertexIndex)

Gets all indices of the mesh vertices that a given topology vertex represents.

SortEdges()

Sorts the edge list for the mesh topology vertex list so that the edges are in radial order when you call ConnectedTopologyVertices. A non-manifold edge is treated as a boundary edge with respect to sorting. If any boundary or non-manifold edges end at the vertex, then the first edge will be a boundary or non-manifold edge.

SortEdges(int topologyVertexIndex)

Sorts the edge list for as single mesh topology vertex so that the edges are in radial order when you call ConnectedTopologyVertices. A non-manifold edge is treated as a boundary edge with respect to sorting. If any boundary or non-manifold edges end at the vertex, then the first edge will be a boundary or non-manifold edge.

TopologyVertexIndex(int vertexIndex)

Gets the topology vertex index for an existing mesh vertex in the mesh's VertexList.
