Functions

matrixEquals3(b: any, a: any, tolerance: any): boolean

Parameters:

• b any
• a any
• tolerance any

Returns: boolean

Calls:

• Math.abs

Code

function matrixEquals3( b, a, tolerance ) {

    tolerance = tolerance || 0.0001;
    if ( a.elements.length != b.elements.length ) {

        return false;

    }

    for ( let i = 0, il = a.elements.length; i < il; i ++ ) {

        const delta = Math.abs( a.elements[ i ] - b.elements[ i ] );
        if ( delta > tolerance ) {

            return false;

        }

    }

    return true;

}

toMatrix4(m3: any): Matrix4

Parameters:

• m3 any

Returns: Matrix4

Code

function toMatrix4( m3 ) {

    const result = new Matrix4();
    const re = result.elements;
    const me = m3.elements;
    re[ 0 ] = me[ 0 ];
    re[ 1 ] = me[ 1 ];
    re[ 2 ] = me[ 2 ];
    re[ 4 ] = me[ 3 ];
    re[ 5 ] = me[ 4 ];
    re[ 6 ] = me[ 5 ];
    re[ 8 ] = me[ 6 ];
    re[ 9 ] = me[ 7 ];
    re[ 10 ] = me[ 8 ];

    return result;

}
