Matrix3D.IsIdentity Property

Determines whether this Matrix3D structure is an identity Matrix3D.

Namespace:  System.Windows.Media.Media3D
Assembly:  System.Windows (in System.Windows.dll)

public bool IsIdentity { get; }

Property Value

Type: System.Boolean
true if the Matrix3D is an identity Matrix3D; otherwise, false. The default value is true.

In an identity matrix, all coefficients are 0 except the [1,1][2,2][3,3][4,4] coefficients, which are set to 1. The identity matrix differs from other matrices because when it is applied to vertices, they are unchanged. The identity matrix is used as the starting point for matrices that modify vertex values to create rotations, translations, and any other transformations that can be represented by a 4 × 4 matrix.
