如何在框的每个面上添加文本[JavaFX]

该解决方案基于此问题的答案，其中使用CuboidMesh了FXyz库中的。

主要思想是使用图像作为立方体的纹理。内置的JavaFX
Box会将此图像应用于6张面孔中的每张，因此，如果我们要
在每张面孔中使用不同的文本，则必须使用CuboidMesh，它利用
了净图片：

The cube can be generated as:

CuboidMesh cuboid = new CuboidMesh(100f, 100f, 100f);cuboid.setTextureModeImage(getClass().getResource("net.png").toExternalForm());

现在的想法是在6个面的每一个中写入文本，并保存纹理
图像，以备后用。

此方法将生成此网络映像：

private Image generateNet(String face1, String face2, String face3, String face4, String face5, String face6) {    GridPane grid = new GridPane();    grid.setAlignment(Pos.CENTER);    Label label1 = new Label(face1);    label1.setRotate(90);    GridPane.setHalignment(label1, HPos.CENTER);    Label label2 = new Label(face2);    GridPane.setHalignment(label2, HPos.CENTER);    Label label3 = new Label(face3);    GridPane.setHalignment(label3, HPos.CENTER);    Label label4 = new Label(face4);    GridPane.setHalignment(label4, HPos.CENTER);    Label label5 = new Label(face5);    GridPane.setHalignment(label5, HPos.CENTER);    Label label6 = new Label(face6);    label6.setRotate(90);    GridPane.setHalignment(label6, HPos.CENTER);    grid.add(label1, 1, 0);    grid.add(label2, 0, 1);    grid.add(label3, 1, 1);    grid.add(label4, 2, 1);    grid.add(label5, 3, 1);    grid.add(label6, 1, 2);    grid.setGridLinesVisible(true);    ColumnConstraints col1 = new ColumnConstraints();    col1.setPercentWidth(25);    ColumnConstraints col2 = new ColumnConstraints();    col2.setPercentWidth(25);    ColumnConstraints col3 = new ColumnConstraints();    col3.setPercentWidth(25);    ColumnConstraints col4 = new ColumnConstraints();    col4.setPercentWidth(25);    grid.getColumnConstraints().addAll(col1, col2, col3, col4);    RowConstraints row1 = new RowConstraints();    row1.setPercentHeight(33.33);    RowConstraints row2 = new RowConstraints();    row2.setPercentHeight(33.33);    RowConstraints row3 = new RowConstraints();    row3.setPercentHeight(33.33);    grid.getRowConstraints().addAll(row1, row2, row3);    grid.setPrefSize(600, 450);    Scene tmpScene = new Scene(grid);    tmpScene.getStylesheets().add(getClass().getResource("style.css").toExternalForm());    return grid.snapshot(null, null);}

where

style.css

.root {    -fx-background-color: white;}.label {    -fx-font-size: 6em;}

With it, the labels size and font can be adjusted properly.

Now you can generate a net image for any text:

Image net = generateNet("1", "2", "3", "4", "5", "6");

Finally, you can apply this texture to the cuboid:

PhongMaterial mat = new PhongMaterial();mat.setDiffuseMap(net);cuboid.setMaterial(mat);
