Description Sven Gothel 2010-03-24 07:47:35 CET

---- Reported by gusgus84 2005-03-01 14:28:36 ----

-Using a PowerBook G4 with an ATI 9800XT, up to date with Software Update

-Runnning the following program: 

-When set to 3D mode (Simulation menu->Dimension->3 Dimensions), the clipping 
panes set just outside the walls cause them to only be partially rendered.

Here's a basic gist of what's going on in the code (works fine on Mac with 
Nvidia and ALL PC's I've tried it on).

double clipDistance=1.0d;
double w=getSize().width, h=getSize().height, d=curZSize;
double w2=w/2, h2=h/2, d2=d/2;
//Look at the center of the box
myGLU.gluLookAt(w2,h2, camz,
                w2,h2, 0,
		0, 1, 0);
//Rotate the box to make it look like the camera is moving
myGL.glRotatef((float)GUIGlobal.camAngleY,0,1, 0);
double angle=camAngleY*Math.PI/180;
myGL.glRotatef((float)camAngleX,(float)Math.cos(angle),0, (float)Math.sin
//Set clipping planes to be just outside of the box
myGL.glClipPlane(GL.GL_CLIP_PLANE0,new double[]{1,0,0,clipDistance});
myGL.glClipPlane(GL.GL_CLIP_PLANE2,new double[]{0,1,0,clipDistance});
myGL.glClipPlane(GL.GL_CLIP_PLANE4,new double[]{0,0,1,clipDistance});
myGL.glClipPlane(GL.GL_CLIP_PLANE1,new double[]{1,0,0,w+clipDistance});
myGL.glClipPlane(GL.GL_CLIP_PLANE5,new double[]{0,0,1,d+clipDistance});
myGL.glClipPlane(GL.GL_CLIP_PLANE3,new double[]{0,1,0,h+clipDistance});

Correction: It was a Radeon 9600, NOT 9800

This is highly unlikely to be a bug in JOGL, but rather in your vendor's OpenGL
drivers. I would suggest trying JOGL 1.1 b10 and if the problem persists then
file a bug with Apple. You might want to try on a Windows machine with an ATI
card as well and if the problem occurs there then file a bug with ATI using
their web feedback form.

Have you tested with JOGL 1.1 b10, and does it change the behavior?

The submitter has indicated that the problem is also reproducible with a C++
program, so it is likely to be a bug in the drivers rather than in JOGL. Closing
this as "works for me".
