如何使用Java / Javascript将.stl文件转换为.x3d文件

public class STLToX3DConverter {
    public static void main(String[] args) {

        Scene scene = null;
        try {
            STLFileReader stlReader = new STLFileReader(stlFilePath);
            scene = stlReader.load();
        } catch (FileNotFoundException e) {

            e.printStackTrace();
        } catch (IncorrectFormatException e) {
