MeshFace

MeshFace 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.

Constructors (2)

MeshFace(int a, int b, int c, int d)

Constructs a new quadrangular Mesh face.

MeshFace(int a, int b, int c)

Constructs a new triangular Mesh face.

Properties (8)

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

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

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

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.

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.

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.

Item

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

Unset

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

Methods (14)

CompareTo(MeshFace other)

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.

Equals(MeshFace other)

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

Equals(Object obj)

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

Flip()

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

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.

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.

IsValid(Point3d[] points)

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.

IsValid(Int32 vertexCount)

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.

IsValidEx(ref Point3d[] points)

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.

Repair(Point3d[] points)

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

RepairEx(ref Point3d[] points)

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

Set(Int32 a,Int32 b,Int32 c,Int32 d)

Sets all the corners for this face as a quad.

Set(Int32 a,Int32 b,Int32 c)

Sets all the corners for this face as a triangle.

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.

Operators (2)

Determines whether two MeshFace structures have different values.

Determines whether two MeshFace structures have equal values.
