updateMatrixWorld method

void updateMatrixWorld([ bool force = false ])

Implementation

		this.children[ 0 ].material.color.set( this.color );

	} else {

		this.material.color.copy( this.light.color ).multiplyScalar( this.light.intensity );

		// prevent hue shift
		var c = this.material.color;
		var max = Math.max3( c.r, c.g, c.b );
		if ( max > 1 ) c.multiplyScalar( 1 / max );

		this.children[ 0 ].material.color.copy( this.material.color );

	}

	// ignore world scale on light
	this.matrixWorld.extractRotation( this.light.matrixWorld ).scale( this.scale ).copyPosition( this.light.matrixWorld );

	this.children[ 0 ].matrixWorld.copy( this.matrixWorld );
