Why is the viewing port

[Java Cool Dude]

a bit different in Xith3D than what it feels like in Java3D?
I mean in one of my port, I set the primary TransformGroup 850 into the canvas3D whereas I had to get it 350 unit closer, 500, in Xith3D to achieve a better resemblance.
Java3D  t3D.setTranslation(new Vector3f(0,0,-850));
Xith3D   t3D.setTranslation(new Vector3f(0,0,-500));

Are you setting the field of view the same in both instances?  We use the standard mesa perspective calculation, so I would not expect differences.

[Java Cool Dude]

Could you please post some code as in:

1   2   3   4   5   6   7   8   9   10

locale.addBranchGraph(branchGroup());     virtualUniverse.addLocale(locale);     virtualUniverse.addView(view);     canvasPeer   = renderPeer.makeCanvas(canvasParent,canvasWidth,canvasHeight,32,false);     canvasPeer.getComponent().addKeyListener(this);     canvas.set3DPeer(canvasPeer);     canvas.requestFocus();     view.addCanvas3D(canvas);

1	view.setFieldOfView((float) Math.toRadians(28));

I don't know what the default field of view is for Java3D, but you can use this same method in both to make sure it is the same.

I figured out Java3D's field of view after many attempts; 22.5.
Therefore to have Java3D's default view in Xith3D, one must include the following line:

1	view.setFieldOfView((float) Math.toRadians(22.5));

PS: Both demos are running the same amount of particles, notice the difference in the frame rate
PS2: the only difference in code is how to load a texture and set up a canvas3D x 2
