Bilboarding when object has parent

<< < (2/2)

Klaudiusz:
Something wrong. It goes crazy when parent object is moving (translated).

See attached example:


--- Code: ---import java.awt.Color;

import com.threed.jpct.*;

public class TestBB {

public static void main(String[] args) {
World w = new World();
FrameBuffer fb = new FrameBuffer(800, 600, FrameBuffer.SAMPLINGMODE_GL_AA_2X);
fb.disableRenderer(IRenderer.RENDERER_SOFTWARE);
fb.enableRenderer(IRenderer.RENDERER_OPENGL);
Object3D Toy= Primitives.getCube(10);


TextureManager tm = TextureManager.getInstance();
Texture vt = new Texture("blue067.jpg");

tm.addTexture("uv", vt);


TextureInfo ti=new TextureInfo(tm.getTextureID("uv"));
Toy.calcTextureWrapSpherical();
Toy.setTexture(ti);

Object3D Toy2=Toy.cloneObject();
Toy2.translate(35, 0, 0);
Toy.addChild(Toy2);
Toy2.setBillboarding(Object3D.BILLBOARDING_ENABLED);

w.getCamera().moveCamera(Camera.CAMERA_MOVEOUT, 200);
w.getCamera().moveCamera(Camera.CAMERA_MOVEUP, 50);
w.setAmbientLight(250, 250, 250);
Toy.build();
w.addObject(Toy);
Toy2.build();
w.addObject(Toy2);


while(!org.lwjgl.opengl.Display.isCloseRequested()) {

fb.clear(Color.PINK);
w.renderScene(fb);
w.draw(fb);
fb.update();
fb.displayGLOnly();

Toy.rotateY(-0.02f);
Toy.translate(0.01f,0,0);



try {
Thread.sleep(10);
} catch(Exception e) {}

}
fb.dispose();

}

}

--- End code ---

EgonOlsen:
I expected something to be wrong...it was just too easy... ;)
Thanks for the test case, i'll look into it.

EgonOlsen:
I've updated the release version. Please have a look at the issue again to see, if this fixes your problem.

Klaudiusz:
