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)
SyntaxThe MeshFace type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | MeshFace(Int32, Int32, Int32) |
Constructs a new triangular Mesh face.
|
| MeshFace(Int32, Int32, Int32, Int32) |
Constructs a new quadrangular Mesh face.
|
Properties| Name | Description | |
|---|---|---|
 | A |
Gets or sets the first corner index of the mesh face.
|
| B |
Gets or sets the second corner index of the mesh face.
|
| C |
Gets or sets the third corner index of the mesh face.
|
| 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.
|
| 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| Name | Description | |
|---|---|---|
| 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. |
| Equals(MeshFace) |
Returns a value indicating whether the other mesh face
has precisely the same value as the current one.
|
| Equals(Object) |
Returns a value indicating whether the other object obj
has precisely the same value as the current one.
(Overrides ValueTypeEquals(Object).) |
| 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.
(Overrides ValueTypeGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| 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(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.
|
| 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.
|
| 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.
|
| Repair |
Attempts to repair this mesh face by taking both face indexes and
actual vertex locations into account.
|
| RepairEx |
Attempts to repair this mesh face by taking both face indexes and
actual vertex locations into account.
|
| Set(Int32, Int32, Int32) |
Sets all the corners for this face as a triangle.
|
| Set(Int32, Int32, Int32, Int32) |
Sets all the corners for this face as a quad.
|
| 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 ValueTypeToString.) |
Operators| Name | Description | |
|---|---|---|
 | Equality |
Determines whether two MeshFace structures have equal values.
|
| Inequality |
Determines whether two MeshFace structures have different values.
