Return Value

CopyAndInvert returns a new SilverSharp.MATRIX object if successful, or null if the original matrix has no inversion.

Example

The following code shows how to make an inverse copy of a matrix. The MATRIX mx2 will contain the inverse transformation matrix of mx1 when finished.

 

C# Code

 

 using SilverSharp;

 

 . . .

 

 MATRIX mx1 = new MATRIX();

 

 mx1.Scale(0.5, 0.5, 1.0);

 

 MATRIX mx2 = mx1.CopyAndInvert();

 

 

The following code is equivalent:

 

C# Code

 

 using SilverSharp;

 

 . . .

 

 MATRIX mx1 = new MATRIX();

 

 mx1.Scale(0.5, 0.5, 1.0);

 

 MATRIX mx2 = new MATRIX(mx1);  // Use a copy constructor

 

 mx2.Invert();  // Invert the copy
