Syntax
public class MeshVertexNormalList : IResizableList<Vector3f>, IList<Vector3f>, ICollection<Vector3f>, IEnumerable<Vector3f>, IEnumerable, IList, ICollection, IReadOnlyList<Vector3f>, IReadOnlyCollection<Vector3f>The MeshVertexNormalList type exposes the following members.
Properties
Name
Description
Public Property
Capacity
Gets or sets the amount of vertex normals that the list can hold without resizing.
Public Property
Count
Gets or sets the number of mesh vertex normals.
Public Property
Item
Gets or sets the vertex at the given index. The index must be valid or an IndexOutOfRangeException will be thrown.
Methods
Name
Description
Public Method
Add(Vector3d)
Adds a new vertex normal at the end of the list.
Public Method
Add(Vector3f)
Adds a new vertex normal at the end of the list.
Public Method
Add(Double, Double, Double)
Adds a new vertex normal at the end of the list.
Public Method
Add(Single, Single, Single)
Adds a new vertex normal at the end of the list.
Public Method
AddRange
Appends a collection of normal vectors.
Public Method
Clear
Clears the vertex normal collection on the mesh.
Public Method
Code Example
ComputeNormals
Computes the vertex normals based on the physical shape of the mesh.
Public Method
Destroy
Releases all memory allocated to store vertex normals. The list capacity will be 0 after this call.
Subsequent calls can add new items.
Public Method
Equals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected Method
Finalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public Method
Flip
Reverses direction of all vertex normals
This is the same as Mesh.Flip(true, false, false)
Public Method
GetEnumerator
Gets an enumerator that yields all normals (vectors) in this collection.
Public Method
GetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public Method
GetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected Method
MemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public Method
SetNormal(Int32, Vector3d)
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.
Public Method
SetNormal(Int32, Vector3f)
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.
Public Method
SetNormal(Int32, Double, Double, Double)
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.
Public Method
SetNormal(Int32, Single, Single, Single)
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.
Public Method
SetNormals
Sets all normal vectors in one go. This method destroys the current normal array if it exists.
Public Method
ToFloatArray
Copies all vertex normals to a linear array of float in x,y,z order
Public Method
ToString
Returns a string that represents the current object.
(Inherited from Object.)
Public Method
UnitizeNormals
Unitizes all vertex normals.
