在javafx中将纹理应用于网格

Question

我在使用JavaFX和FXyz 0.1.1将纹理应用于网格时遇到了问题。

我找到this question，即使有详细的答案也无法弄明白。我从头开始，完全从答案中复制代码，场景是黑色的，没有可见的二十面体。

我正在使用Java 8.提供的图像是一个gif，代码将其作为png引用。我已经尝试了文件的png和gif版本。据我所知，其他一切与答案中的代码完全一样。

我能够运行this并且没有问题地纹理该球体，但我希望能够使用icosohedron而不是球体。

如果您使用FXyz library，您可以非常轻松地将不同的纹理应用于二十面体或library中可以找到的任何不同基元。

此代码段显示了5种不同的纹理模式：

@Override
public void start(Stage primaryStage) {
    PerspectiveCamera camera = new PerspectiveCamera(true);   
    camera.setTranslateY(3);
    camera.setTranslateX(4);
    camera.setTranslateZ(-15);

    IcosahedronMesh icoLine = new IcosahedronMesh(100, 0);
    icoLine.setDrawMode(DrawMode.LINE);
    icoLine.getTransforms().addAll(new Rotate(10, Rotate.X_AXIS), new Rotate(-20, Rotate.Y_AXIS));

    IcosahedronMesh icoColor = new IcosahedronMesh(100, 0);
    icoColor.setTextureModeNone(Color.LIGHTGREEN);
    icoColor.getTransforms().addAll(new Rotate(20, Rotate.X_AXIS), new Rotate(-20, Rotate.Y_AXIS));

    IcosahedronMesh icoFunction = new IcosahedronMesh(100, 0);
    icoFunction.setTextureModeVertices3D(1530, p -> Math.cos(p.z));
    icoFunction.getTransforms().addAll(new Rotate(30, Rotate.X_AXIS), new Rotate(-20, Rotate.Y_AXIS));

    IcosahedronMesh icoFaces = new IcosahedronMesh(100, 0);
    icoFaces.setTextureModeFaces(5);
    icoFaces.getTransforms().addAll(new Rotate(20, Rotate.X_AXIS), new Rotate(-10, Rotate.Y_AXIS));

    IcosahedronMesh icoImage = new IcosahedronMesh(100, 0);
    icoImage.setTextureModeImage(getClass().getResource("icon.jpg").toExternalForm());
    icoImage.getTransforms().addAll(new Rotate(20, Rotate.X_AXIS), new Rotate(-20, Rotate.Y_AXIS));

    IcosahedronMesh icoPattern = new IcosahedronMesh(100, 0);
    icoPattern.setTextureModePattern(Patterns.CarbonPatterns.CARBON_KEVLAR, 100);
    icoPattern.getTransforms().addAll(new Rotate(20, Rotate.X_AXIS), new Rotate(-30, Rotate.Y_AXIS));


    GridPane grid = new GridPane();
    grid.add(new Group(icoLine), 0, 0);
    grid.add(new Group(icoColor), 1, 0);
    grid.add(new Group(icoFunction), 2, 0);

    grid.add(new Group(icoFaces), 0, 1);
    grid.add(new Group(icoImage), 1, 1);
    grid.add(new Group(icoPattern), 2, 1);
    Scene scene = new Scene(grid, 600, 400, true, SceneAntialiasing.BALANCED);
    scene.setCamera(camera);

    primaryStage.setScene(scene);
    primaryStage.setTitle(("Icosahedron - FXyz3D"));
    primaryStage.show(); 

}
