How to create custom 3d model in JavaFX 8?

Question

I tried to make a plane in JavaFX application using official tutorial and has the next code:

Image diifuseMap = new Image(getClass().getResource("t.jpg").toExternalForm());
    TriangleMesh planeMesh = new TriangleMesh();
    float[] points = {
            -5, 5, 0,
            -5, -5, 0,
            5, 5, 0,
            5, -5, 0
    };
    float[] texCoords = {
            0, 0,
            0, 1,
            1, 0,
            1, 1
    };
    int[] faces = {
            0, 0, 1, 1, 2, 2,
            2, 2, 3, 3, 1, 1
    };
    planeMesh.getPoints().addAll(points);
    planeMesh.getTexCoords().addAll(texCoords);
    planeMesh.getFaces().addAll(faces);
    MeshView meshView =   new MeshView(planeMesh);
    meshView.setMaterial(new PhongMaterial(Color.BLACK, diifuseMap, null, null, null));
    Group3D plane = new Group3D(new MeshView(planeMesh));

But, unfortunately, nothing appeared in the scene. Can anybody explain how to create my own 3d models in JavaFX? And is it possible to create them without texture(I want wireframe model)?

Answer 1

Step 1:List the points

cube.getPoints().addAll(
    0, 0, 100,      //P0
    100, 0, 100,    //P1
    0, 100, 100,    //P2
    100, 100, 100,  //P3
    0, 0, 0,        //P4
    100, 0, 0,      //P5
    0, 100, 0,      //P6
    100, 100, 0     //P7
);

Step 2:List the texture points

cube.getTexCoords().addAll(
    0.25f, 0,       //T0
    0.5f, 0,        //T1
    0, 0.25f,       //T2
    0.25f, 0.25f,   //T3
    0.5f, 0.25f,    //T4
    0.75f, 0.25f,   //T5
    1, 0.25f,       //T6
    0, 0.5f,        //T7
    0.25f, 0.5f,    //T8
    0.5f, 0.5f,     //T9
    0.75f, 0.5f,    //T10
    1, 0.5f,        //T11
    0.25f, 0.75f,   //T12
    0.5f, 0.75f     //T13
);

Step 3: List the faces (it Mixed 3D points and Texture points counter-clockwise (or right-hand rule))

cube.getFaces().addAll(
    5,1,4,0,0,3     //P5,T1 ,P4,T0  ,P0,T3
    ,5,1,0,3,1,4    //P5,T1 ,P0,T3  ,P1,T4
    ,0,3,4,2,6,7    //P0,T3 ,P4,T2  ,P6,T7
    ,0,3,6,7,2,8    //P0,T3 ,P6,T7  ,P2,T8
    ,1,4,0,3,2,8    //P1,T4 ,P0,T3  ,P2,T8
    ,1,4,2,8,3,9    //P1,T4 ,P2,T8  ,P3,T9
    ,5,5,1,4,3,9    //P5,T5 ,P1,T4  ,P3,T9
    ,5,5,3,9,7,10   //P5,T5 ,P3,T9  ,P7,T10
    ,4,6,5,5,7,10   //P4,T6 ,P5,T5  ,P7,T10
    ,4,6,7,10,6,11  //P4,T6 ,P7,T10 ,P6,T11
    ,3,9,2,8,6,12   //P3,T9 ,P2,T8  ,P6,T12
    ,3,9,6,12,7,13  //P3,T9 ,P6,T12 ,P7,T13
);
