MeshVertexNormalList

MeshVertexNormalList class

Provides access to the Vertex Normals of a Mesh.

Derived Classes:

Namespace: Rhino.Geometry.Collections
MeshVertexNormalList: references

Properties (3)

Capacity

Gets or sets the amount of vertex normals that the list can hold without resizing.

Count

Gets or sets the number of mesh vertex normals.

Item

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

Methods (17)

Add(double x, double y, double z)

Adds a new vertex normal at the end of the list.

Add(float x, float y, float z)

Adds a new vertex normal at the end of the list.

Add(Vector3d normal)

Adds a new vertex normal at the end of the list.

Add(Vector3f normal)

Adds a new vertex normal at the end of the list.

AddRange(Vector3f[] normals)

Appends a collection of normal vectors.

Clear()

Clears the vertex normal collection on the mesh.

ComputeNormals()

Computes the vertex normals based on the physical shape of the mesh.

Destroy()

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

Flip()

Reverses direction of all vertex normals
This is the same as Mesh.Flip(true, false, false)

GetEnumerator()

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

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

Sets or adds a vertex normal to the list.
If [index] is less than [Count], the existing vertex normal at [index] will be modified.
If [index] equals [Count], a new vertex normal is appended to the end of the list.
If [index] is larger than [Count], the function will return false.

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

Sets or adds a normal to the list.
If [index] is less than [Count], the existing vertex normal at [index] will be modified.
If [index] equals [Count], a new vertex normal is appended to the end of the list.
If [index] is larger than [Count], the function will return false.

SetNormal(int index, Vector3d normal)

Sets or adds a vertex normal to the list.
If [index] is less than [Count], the existing vertex normal at [index] will be modified.
If [index] equals [Count], a new vertex normal is appended to the end of the list.
If [index] is larger than [Count], the function will return false.

SetNormal(int index, Vector3f normal)

Sets or adds a vertex normal to the list.
If [index] is less than [Count], the existing vertex normal at [index] will be modified.
If [index] equals [Count], a new vertex normal is appended to the end of the vertex list.
If [index] is larger than [Count], the function will return false.

SetNormals(Vector3f[] normals)

Sets all normal vectors in one go. This method destroys the current normal array if it exists.

ToFloatArray()

Copies all vertex normals to a linear array of float in x,y,z order

UnitizeNormals()

Unitizes all vertex normals.
