Sorry, removed the includes and stuff. Line 62 is the bottom of the constructor

Code: [Select]
world.getCamera().lookAt(sonic[1].getTransformedCenter());

Full code listing:

Code: [Select]
public class ModelRenderer {

private World world;
private FrameBuffer buffer;
private Object3D box;
private Object3D[] sonic;
private Object3D merged;
private JFrame frame;

public static void main(String[] args) throws Exception {
new ModelRenderer().loop();
}

public ModelRenderer() throws Exception {
frame = new JFrame("Model Renderer");
frame.setSize(800, 600);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

world = new World();
world.setAmbientLight(0, 255, 0);

TextureManager.getInstance().addTexture("sonic", new Texture("Sonic.JPG"));

File snc = new File("Sonic.obj");
InputStream objIn = new FileInputStream(snc);
File sncMtl = new File("Sonic.mtl");
InputStream mtlIn = new FileInputStream(sncMtl);
sonic = Loader.loadOBJ(objIn, mtlIn, 1);
merged = Object3D.mergeAll(sonic);
world.addObject(merged);

world.getCamera().setPosition(0, 0, -100);
world.getCamera().lookAt(sonic[1].getTransformedCenter());
}

private void loop() throws Exception {
buffer = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_NORMAL);

while (frame.isShowing()) {
box.rotateY(0.01f);
buffer.clear(java.awt.Color.BLUE);
world.renderScene(buffer);
world.draw(buffer);
buffer.update();
buffer.display(frame.getGraphics());
Thread.sleep(10);
}
buffer.disableRenderer(IRenderer.RENDERER_OPENGL);
buffer.dispose();
frame.dispose();
System.exit(0);
}
}

My application is package com.codeturkey.modelrenderer. This only happens when I add the two lines to merge the meshes and to add the merged model to the world, those are the only two lines I add.

Oh I was trying to load the serialized data on the desktop version. However the second error message is from trying a merge the meshes of a .OBJ file not a serialized file.

So.. I'm trying to load my serialized data and I'm getting:

"No octree found in serialized data!
java.lang.ArrayIndexOutOfBoundsException: 49787
    at com.threed.jpct.Object3D.recreateTextureCoords(Unknown Source)
    at com.threed.jpct.Object3D.build(Unknown Source)
    ...."

EDIT: I'm also getting exception's while trying to display an Object3D returned by mergeAll(Object3D[]).

"Exception in thread "main" java.lang.reflect.InvocationTargetException
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    ...."

Thanks, understanding the format helped a lot! I seem to have got my serialization working; but I see a large increase in file size when merging the meshes (ie. around normal file size), is this normal?

Starting with the serialization issue:

I was making a quick GUI serialization tool last night, and realised I did not fully understand the LoadOBJ parameters. I read the Wiki but do not quite understand the language used. My interpretation is that Textures are referenced inside the .Obj file, and that the material file is something different entirely? Currently what I'm doing is, getting InputStreams for both files, using LoadOBJ, using build() and strip(), and serialising, is that correct?

The lighting issue:

Does the default setup/shader only support one light? I thought I had read that it supported more, but I cant seem to get any more working.

Thanks in Advance ;)

EDIT: Just discovered the shader only supports one light, but could still do with some help understanding the serialiser.
