MeshFaceNormalList

MeshFaceNormalList class

Provides access to the Face normals of a Mesh.

Derived Classes:

Namespace: Rhino.Geometry.Collections
MeshFaceNormalList: references

Properties (3)

Capacity

Gets or sets the total number of face normals the internal data structure can hold without resizing.

Count

Gets or sets the number of mesh face normals.

Item

Gets or sets the face normal at the given face index. The index must be valid or an IndexOutOfRangeException will be thrown.

Methods (13)

AddFaceNormal(double x, double y, double z)

Appends a face normal to the list of mesh face normals.

AddFaceNormal(float x, float y, float z)

Appends a face normal to the list of mesh face normals.

AddFaceNormal(Vector3d normal)

Appends a face normal to the list of mesh face normals.

AddFaceNormal(Vector3f normal)

Appends a face normal to the list of mesh face normals.

Clear()

Clears the Face Normal list on the mesh.

ComputeFaceNormals()

Computes all the face normals for this mesh based on the physical shape of the mesh.

Destroy()

Releases all memory allocated to store face normals. The list capacity will be 0 after this call.
Subsequent calls can add new items.

GetEnumerator()

Gets an enumerator that yields all normals (vectors) in this collection.

SetFaceNormal(int index, double x, double y, double z)

Sets a face normal vector at an index using three double-precision numbers.

SetFaceNormal(int index, float x, float y, float z)

Sets a face normal vector at an index using three single-precision numbers.

SetFaceNormal(int index, Vector3d normal)

Sets a face normal vector at an index using a single-precision vector.

SetFaceNormal(int index, Vector3f normal)

Sets a face normal vector at an index using a single-precision vector.

UnitizeFaceNormals()

Unitizes all the existing face normals.
