MeshFace

Public Struct

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 : IEquatable<MeshFace>,
  IComparable<MeshFace>, IComparable

The MeshFace type exposes the following members.

Constructors

Name

Description

---

Public Method

MeshFace(Int32, Int32, Int32)

Constructs a new triangular Mesh face.

---

Public Method

MeshFace(Int32, Int32, Int32, Int32)

Constructs a new quadrangular Mesh face.

Properties

Name

Description

---

Public Property

A

Gets or sets the first corner index of the mesh face.

---

Public Property

B

Gets or sets the second corner index of the mesh face.

---

Public Property

C

Gets or sets the third corner index of the mesh face.

---

Public Property

D

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 Property

IsQuad

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 Property

IsTriangle

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 Property

Item

Gets or sets the vertex index associated with an entry in this face.

---

Public Property
Static Member

Unset

Gets an Unset MeshFace. Unset faces have Int32.MinValue for all corner indices.

---

Methods

Name

Description

---

Public Method

CompareTo

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 Method

Equals(MeshFace)

Returns a value indicating whether the other mesh face has precisely the same value as the current one.

---

Public Method

Equals(Object)

Returns a value indicating whether the other object obj has precisely the same value as the current one.

(Overrides ValueType.Equals(Object).)

---

Public Method

Flip

Reverses the orientation of the face by swapping corners. The first corner is always maintained.

---

Public Method

GetHashCode

Returns a runtime-stable hash code for the current mesh face. You are not allowed to rely on persistence of this hash code in serialization, but for each version of RhinoCommon, this hash code will be the same for each mesh face.

(Overrides ValueType.GetHashCode..)

---

Public Method

GetType

Gets the Type of the current instance.

(Inherited from Object.)

---

Public Method

IsValid.

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 Method

IsValid(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 Method

IsValid(.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 Method

IsValidEx

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 Method
Repair

Attempts to repair this mesh face by taking both face indexes and actual vertex locations into account.

---

Public Method
RepairEx

Attempts to repair this mesh face by taking both face indexes and actual vertex locations into account.

---

Public Method

Set(Int32, Int32, Int32)

Sets all the corners for this face as a triangle.

---

Public Method

Set(Int32, Int32, Int32, Int32)

Sets all the corners for this face as a quad.

---

Public Method

ToString

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 ValueType.ToString..)

---

Public Operator
Static Member
Inequality

Determines whether two MeshFace structures have different values.
