MeshFace Structure

Represents the values of the four indices of a mesh face quad.

If the third and fourth values are the same, this face represents a triangle.

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Syntax
[SerializableAttribute]
public struct MeshFace

The MeshFace type exposes the following members.

Constructors
  NameDescription
Public methodMeshFace(Int32, Int32, Int32)
Constructs a new triangular Mesh face.
Public methodMeshFace(Int32, Int32, Int32, Int32)
Constructs a new quadrangular Mesh face.

Properties
  NameDescription
Public propertyA
Gets or sets the first corner index of the mesh face.
Public propertyB
Gets or sets the second corner index of the mesh face.
Public propertyC
Gets or sets the third corner index of the mesh face.
Public propertyD
Gets or sets the fourth corner index of the mesh face. If D equals C, the mesh face is considered to be a triangle rather than a quad.
Public propertyIsQuad
Gets a value indicating whether or not this mesh face is a quad. A mesh face is considered to be a triangle when C does not equal D, thus it is possible for an Invalid mesh face to also be a quad.
Public propertyIsTriangle
Gets a value indicating whether or not this mesh face is a triangle. A mesh face is considered to be a triangle when C equals D, thus it is possible for an Invalid mesh face to also be a triangle.
Public propertyItem
Gets or sets the vertex index associated with an entry in this face.
Public propertyStatic memberUnset
Gets an Unset MeshFace. Unset faces have Int32.MinValue for all corner indices.

Methods
  NameDescription
Public methodCompareTo
Compares this MeshFace with another MeshFace and returns a value of 1, 0, or -1, referring to dictionary order.

Index evaluation priority is first A, then B, then C, then D.

Public methodEquals(Object) (Inherited from ValueType.)
Public methodEquals(Object)
Returns a value indicating whether the other object obj has precisely the same value as the current one.
(Overrides ValueTypeEquals(Object).)
Public methodEquals(MeshFace)
Returns a value indicating whether the other mesh face has precisely the same value as the current one.
Public methodFlip
Reverses the orientation of the face by swapping corners. The first corner is always maintained.
Public methodGetHashCode (Inherited from ValueType.)
Public methodGetHashCode
Returns a runtime-stable hashcode for the current mesh face. You are not allowed to rely on persistance of this hashcode in serialization, but for each version of RhinoCommon, this hashcode will be the same for each mesh face.
(Overrides ValueTypeGetHashCode.)
Public methodGetType (Inherited from Object.)
Public methodIsValid
Gets a value indicating whether or not this mesh face is considered to be valid. Note that even valid mesh faces could potentially be invalid in the context of a specific Mesh, if one or more of the corner indices exceeds the number of vertices on the mesh. If you want to perform a complete validity check, use IsValid(int) instead.
Public methodIsValid(Int32)
Gets a value indicating whether or not this mesh face is considered to be valid. Unlike the simple IsValid function, this function takes upper bound indices into account.
Public methodIsValid(Point3d)
Gets a value indicating whether or not this mesh face is considered to be valid. Unlike the simple IsValid function, this function takes actual point locations into account.
Public methodRepair
Attempts to repair this mesh face by taking both face indexes and actual vertex locations into account.
Public methodSet(Int32, Int32, Int32)
Sets all the corners for this face as a triangle.
Public methodSet(Int32, Int32, Int32, Int32)
Sets all the corners for this face as a quad.
Public methodToString (Inherited from ValueType.)
Public methodToString
Returns a string representation for this MeshFace. This is to provide a meaningful visualization of this structure and is subject to change in newer releases.
(Overrides ValueTypeToString.)

Operators
  NameDescription
Public operatorStatic memberEquality
Determines whether two MeshFace structures have equal values.
Public operatorStatic memberInequality
Determines whether two MeshFace structures have different values.
