SIMatrix4.InvertInPlace

Description

Inverts this matrix (if not singular): this = this^-1

Scripting Syntax

oBoolean = SIMatrix4.InvertInPlace();

Return Value

Boolean True if this matrix has been inverted (not singular); otherwise False.

Examples

JScript Example

/*
        This example demonstrates how to set up a 4x4 matrix, 
        invert it and then trap whether the inversion was
        successful
*/
// Create 4x4 matrices
var aValues = new Array(
        2.0, 3.0, 0.0, 0.0, 
        1.0, 4.0, 0.0, 0.0,
        0.0, 0.0, 1.0, 0.0,
        0.0, 0.0, 0.0, 1.0
);
var m1 = XSIMath.CreateMatrix4(aValues);
var m2 = XSIMath.CreateMatrix4();
// Make the second matrix the inversion of the first
if ( m2.InvertInPlace() ) {
        Application.LogMessage( "Success :-D" );
} else {
        Application.LogMessage( "Failure :-(" );

// Expected result:
// INFO : Success :-D
