---- Reported by pdjensen 2004-03-10 10:29:49 ---- I have been trying to track down a strange jogl lighting problem on some systems which can also reliably cause some of them to hang. The problem is fairly consistent on a 1.33 Ghz Powerbook with the latest OS, Java, tools, and Gregory Pierce's version of jogl (Feb 17, Optimized, but the problem has been there for at least several weeks, if not all along). I also see the problem with the Sep 2003 Win32 libray from the games games-core jogl site. The systems it has hung are new Mac 15" & 17" PB's, a dual cpu G5, and a Win2K system with an ATI Rage 128 VR card. It does not seem to be a problem on Mac 12" PB, iMac, or iBook. You can see the problem by running the JWS app: http://agileimage.com/html/statistics/TimeMachine.jnlp Lighting: In the Window menu, select the last entry (bea/USPopulation.csv) and observe that only three states appear to be lit properly - the rest have just ambient light. Move the slider at the bottom and see the lighting fix itself when Alaska and Hawaii appear. Move the slider back to the beginning and the problem reappears. Select the View/Display/Top 30 and about half are lit ok, Bottom 30 and just 2 are ok, etc. Reshape hangs sytem: Resize the window larger and the familiar old resize bug appears where some of the window is not being rendered, no big deal. But move the split pane divider to make the map less than 32 pixels high, and some systems will hang so that the mouse still moves, but nothing responds. I have to reboot. There is a System.err output to report the reshape size so you can tell when you are close. I'm trying to get some idea of how to track down these problems. I use the Animator, changing the model in the AWT event thread and then updating a reference to the set of call lists to be displayed by the Animator. The display code for each state (one call list per state) is this, where the color c is defined by the state (unless highlighted or hidden): gl.glPushMatrix(); gl.glScaled( xScale, yScale, visible? zScale * value / maxValue: 0.0 ); gl.glTranslatef( -longCenter, -latCenter, 0f ); gl.glMaterialfv(GL.GL_FRONT, GL.GL_AMBIENT_AND_DIFFUSE, c); gl.glCallList( j ); gl.glPopMatrix(); The directional light source is Light0Position = { -1.0f, 2.0f, 2.0f, 0.0f }; The reshape code was lifted fairly directly from the Jogl Gears demo. ---- Additional Comments From kbr 2005-01-28 19:35:52 ---- Is this problem still reproducible? Many bugs have been fixed since this issue was reported, including a workaround for ATI cards that reduces OpenGL rendering to running on a single thread. The latest CVS sources contain a bug fix to Issue 97, which turned out to be a bug in this single-threaded workaround. The current JOGL seems to be fairly robust on my ATI Radeon 9800 Pro. (There is still an outstanding issue with multiple GLCanvas creation on ATI cards: Issue #118.) If the problem is still reproducible, could you please attach a test case to this bug report? Thanks. ---- Additional Comments From kbr 2005-01-31 00:09:36 ---- Comments from pdjensen: ---- I apologize for not following up earlier. Most of the issues described in this bug report are fixed now with the exception that on my Mac 17" 1.33 GHz PowerBook, the repaint leaves sections that are garbage. The lighting problem was my bug. The crashes when resizing to less than a dozen pixels in height no longer happen with JOGL of Nov 19, 2004 on either the PowerBook or my Win2K system. (By the way, I am looking forward to signed JOGL libraries with versions - I'm still re-signing your stuff to maintain control over which version I use). The repaint problem has been with me for as long as I've used JOGL. It does appear that it is no longer a problem on my Win2K system. I am attaching snapshots of the problem. "bad.jpg" is the result of making the application window larger. "good.jpg" is the correct view after moving the divider between the JOGL pane and Swing pane just slightly. The width did not change despite the snapshots - the two images were scaled differently when I converted the tiff screen captures. The video card on the PowerBook is an ATI MOBILITY RADEON 9600. ---- ---- Additional Comments From kbr 2005-01-31 00:10:39 ---- Created an attachment Screenshot of bad behavior on ATI adapter ---- Additional Comments From kbr 2005-01-31 00:11:11 ---- Created an attachment Screenshot of proper behavior ---- Additional Comments From kbr 2005-05-11 09:43:22 ---- With the latest changes to the GLCanvas's resizing code on Mac OS X in JOGL 1.1 b11 I believe all remaining resizing issues should be fixed. Could you please retest your application? Thanks. ---- Additional Comments From kbr 2005-05-12 09:24:48 ---- Submitter has indicated that the recent fix on Mac OS X to always update the context even if the GLCanvas has not been resized has solved all remaining problems. --- Bug imported by sgothel@jausoft.com 2010-03-24 07:46 EDT --- This bug was previously known as _bug_ 67 at https://jogl.dev.java.net/bugs/show_bug.cgi?id=67 Imported an attachment (id=18) Imported an attachment (id=19) The original submitter of attachment 18 [details] is unknown.
