Only texture color is 3D object.
« on: September 11, 2014, 08:22:13 pm »
Hello.
Why does picture of a texture is not displayed and all that displayed is a color of texture? 3Ds file is exported from Blender.

Code: [Select]
public class OneGraphics {

    private World world;
    private FrameBuffer buffer;
    private Object3D model;
    private String[] textures = {"OrnamentBorder0196_9_S"};
    //InputStream inputstream = new FileInputStream("/home/shmex/dddd.png");
   
    public static void main(String[] args) throws Exception{
    new OneGraphics().loop();
    }
   
    public OneGraphics() throws Exception {
       
        world = new World();
        world.setAmbientLight(200, 200, 200);
        //загрузка текстуры
       // Image image = ImageIO.read(new File("/home/***/ff.png"));
        //Texture tex = new Texture(image);
       
        TextureManager.getInstance().addTexture("trd.jpg", new Texture("/home/***/trd.jpg"));
        //TextureManager.getInstance().addTexture("Wood_Che.jpg", new Texture("/home/***/Wood_Che.jpg"));
        //загрузка модели
        model = loadModelfrom3DS("/home/shmex/rr.3ds", 2.5f);
       
        world.addObject(model);
        world.getCamera().setPosition(-10, 10, -10);
        world.getCamera().lookAt(model.getTransformedCenter());
       
    }
   
    private void loop() throws Exception {
       
        buffer = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_NORMAL);
        buffer.disableRenderer(IRenderer.RENDERER_SOFTWARE);
        buffer.enableRenderer(IRenderer.RENDERER_OPENGL); 

        while (!org.lwjgl.opengl.Display.isCloseRequested()) {
           
            model.rotateX(0.01f);
            buffer.clear(java.awt.Color.BLUE);
            world.renderScene(buffer);
            world.draw(buffer);
            buffer.update();
            buffer.displayGLOnly();
            Thread.sleep(10);
        }
       
        buffer.disableRenderer(IRenderer.RENDERER_OPENGL);
        buffer.dispose();
        System.exit(0);
    }
   
    private Object3D loadModelfrom3DS(String filename, float scale) {
        Object3D temp = null;
        Object3D[] file = Loader.load3DS(filename, scale);
       
        if (file.length==1) {
            temp=file[0];
            temp.setTexture("trd.jpg");
            temp.setTransparency(2);
            temp.setCulling(Object3D.CULLING_DISABLED);
            temp.rotateX(-(float)Math.PI/2f);
            temp.rotateMesh();
            temp.setRotationMatrix(new Matrix());
            temp.setAdditionalColor(new Color(100,100,100));
            temp.build();
        }
        return temp;
    }
output:

Most likely because the model has no proper texture coordinates.

Сuriously...

Blender settings mapping:
coordinates: Generated
Projection   : Cube

I don't know much about Blender, but there are different ways to create texture coordinates and at least one of them doesn't make it into exported file formats. Might very well be that this is the case for 'projected'.
