在javafx中将纹理应用于网格 [英] applying texture to mesh in javafx

问题描述

我在使用JavaFX和FXyz 0.1.1将纹理应用到网格时遇到了问题。

我发现

I was having trouble applying a texture to a mesh using JavaFX and FXyz 0.1.1.

I found this question and even with the detailed answer there could not figure it out. I started over from scratch, copying the code from the answer exactly and the scene is black with no visible icosohedron.

I'm using Java 8. The provided image is a gif and the code references it as a png. I've tried it with both png and gif versions of the file. As far as I can tell everything else is exactly as the code in the answer to the referenced question.

I am able to run this and texture that sphere without issue, but I would like to be able to use an icosohedron instead of a sphere.

解决方案

If you are using the FXyz library you can very easily apply different textures to an icosahedron or to any of the different primitives you can find in the library.

This snippet shows 5 different texture modes:

@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(); 

}
