I’m constantly getting this:

It’s probably a JOGL thing right? But do people using Xith get these? Are they common? I’ve the newest available version of jogl (version 1.0alpha), but will try to compile the one on their CVS later on, and see if it anything changes.

I think the fault is probably mine, because I don’t really know how I should deal with creating a new thread to render a new canvas with a different view and universe.

I get the problem when I create a new canvas, and new universe, but using objects from another universe. I “try” to clone them when possible, but cloning things in Xith is not always guaranteed.

Should there be a violation if I try to render the same shape in two different canvas, using different views?

I’m trying many things to try solve this, but any insights or directions are most appreciated.

ps: what’s the way people use to pause the rendering thread? Using .wait() and notify()? Using a pause boolean and while loop?

Which version of Xith3D do you currently use?

Yuri

#3

The current one from CVS, with some minor modifications to ShaperAtomPeer to allow the rendering of quadrics.

Now, the weird part is that the crash only occurs when the objects in my scene ARE NOT of a QuadricSphere type. Very strange.

Do you think that’s breaking the code? I will try using the exact version from CVS (without quadrics) and see what happens. I’ll trying to isolate the problem, and will let you know ;p

What are the ways net.java.games.jogl.impl.windows.WindowsGLImpl.glDrawArrays could cause such ACCESS_VIOLATION? Have you come across those errors before?

I too am getting HotSpot crashes.

In the demo HelloXith3D, replace


// create Cube
Geometry g = Cube.createCubeViaTriangles(0, 0, 0, 1, true);
Shape3D sh = new Shape3D(g);
objRotate.addChild(sh);

with


// create Cube
Geometry g = Cube.createCubeViaTriangles(0, 0, 0, 1, true);
Appearance a=new Appearance();
PolygonAttributes p=new PolygonAttributes();
p.setPolygonMode(PolygonAttributes.POLYGON_LINE);
a.setPolygonAttributes(p);
Shape3D sh=new Shape3D(g, a);
objRotate.addChild(sh);

This causes my program to crash with a

Commenting out the line
// p.setPolygonMode(PolygonAttributes.POLYGON_LINE);
eliminates the crash.

In fact, setting POLYGON_LINE crashes several, but not all, geometric primitives I’ve been playing with.
Am I doing something wrong, or is this a bug?
FWIW, I’m using Xith3D_2004-02-29_cvs.tar.gz

Thanks,

Hmm… strange isn’t? ???

I’m going to try to run it with Java 1.4 and see if it continues. It might be related. Since it’s still a beta relase we might have to leave with that. Should these Exceptions be notified to Sun?
