Examples of org.mt4j.util.math.Vector3D.transform()

org.mt4j.util.math.Vector3D.transform()
Applies a transformation on the vector defined by the given tranformation matrix. @param transformMatrix the transform matrix

    //svgbutton inverse parent relative machen
    svgButtonAbsInv.multLocal(this.getCompToResize().getLocalMatrix());
    //Remove translation for direction vectors(width/height)
    svgButtonAbsInv.removeTranslationFromMatrix();
    //Width vect in svgbutton parent relative space
    v.transform(svgButtonAbsInv);
    float width = v.length();
    return width;
