Added new ForceProcAddressGen directive to GlueGen to force the addresses of the C routines to be fetched even though the functions were being ignored by the core JavaEmitter. Cut down on the number of variants of gluScaleImage and associated routines. Changed the Java signatures of the affected methods to take Buffer again instead of ByteBuffer (as was done during prototyping) to attempt to maintain binary compatibility with current JOGL programs. Fixed bug / problem in gluScaleImage implementation where incorrect scaling of pixel values was being applied in Image.empty_image(); there may be additional problems here for other pixel types.

* Fixed Issue 44: Add pbuffer-based GLJPanel implementation Kenneth Russel2005-02-0313-156/+563
| | | | | | | | | | | | | | | | | | | | | | | | Fixed Issue 61: Make debug variables load from system properties Added a hardware acceleration path for GLJPanel implemented using the GLPbuffer interfaces. If instantiation of the pbuffer fails, the GLJPanel implementation attempts to catch the resulting exception and fall back on the existing software rendering path. The new code has been successfully tested on Windows. This checkin attempts to make the needed changes to the pbuffer implementation on other platforms, but the GLJPanel continues to use software rendering until all platforms can be tested. Additionally, references to static final DEBUG flags have been made settable via system properties. "jogl.verbose" enables certain printing statements. "jogl.debug" enables all debugging printing. "jogl.debug.GLContext" enables the debug printing inside the GLContext class. The system property names are chosen by convention and are not enforced. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@209 232f8b59-042b-4e1e-8c03-345bb8c30851

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (ATI-specific) The root cause of this bug was not the new DummyGL code, but severe bugs in ATI's OpenGL drivers where it appears that if an OpenGL context is ever made current on more than one thread during the lifetime of an application, problems begin to occur such as the SetPixelFormat call failing on the just the next newly-created HDC, or all subsequent SetPixelFormat calls failing on all subsequently-created HDCs. This was occurring because the single-threaded ATI workaround's automatic detection mechanism was not being enabled until the first time a context was made current, but by then it was typically too late; the context was made current on the end user's thread during e.g. Frame.show(), and if it was ever made current on another thread (like the AWT event queue thread, which is where all OpenGL operations are performed when the single-threaded workaround is enabled) then the problems would begin. The failure has only been seen on Windows so far; ATI's drivers on X11 seem to be better behaved. The workaround is to check for the presence of ATI's drivers very early during JOGL's initialization, by looking in the system directory for atioglxx.dll, and enabling the single-threaded workaround if it was found. This workaround causes the attached test case to work properly. Also added some more debugging code to make diagnosing problems like these easier in the future. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@196 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 97: Flickering when using ATI_WORKAROUND Kenneth Russel2005-01-292-14/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | The root cause was that JOGL's single-threaded workaround had a bug where if automatic swap buffer support was disabled, the user's calls to swapBuffers() were not being retargeted to run on the AWT event queue thread, as calls to display() were. The effect of this was that the OpenGL rendering was not necessarily guaranteed to complete before swapBuffers() was called, unless a glFlush() / glFinish() pair was inserted. Interestingly, testing showed that inserting the glFlush() / glFinish() just before the call to swapBuffers(), which was executing on the user's thread rather than the AWT event dispatch thread, did not cause the rendering output to complete properly. This implies either a bug in the implementation of glFlush() / glFinish() on the testing platform or a misunderstanding on my part of how these APIs behave. Putting the flush/finish after all of the OpenGL work done by the user in their display() routine worked correctly. Regardless, the intent of the single-threaded workaround was to cause all OpenGL-related work to be done on the event dispatch thread, which it now does. This fixes the reported problem. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@195 232f8b59-042b-4e1e-8c03-345bb8c30851

* Fixed Issue 54: No GL listener callbacks when setting render thread before ↵Kenneth Russel2005-01-281-0/+19
| | | | | | | | | | | | | | | | | | | | window is visible The issue (or a related one) is still present in the current JOGL build, although the symptom was different: a deadlock upon startup of the application. When the OpenGL context is created in the WindowsOnscreenGLContext implementation, it causes Component.getGraphicsConfiguration() to be called, which causes the AWT tree lock to be grabbed. Under some circumstances, another thread can already hold the AWT tree lock and call GLContext.invokeGL(), which leads to a classic deadlock. Resolved this by eagerly grabbing the tree lock under some circumstances (not all the time) before entering the synchronized invokeGL in (only) the Windows onscreen context implementation. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@193 232f8b59-042b-4e1e-8c03-345bb8c30851
* Partial fix for Issue 88: Add Linux amd64 support to JOGLKenneth Russel2005-01-276-9/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The stub_includes headers and GlueGen config files have been changed to make X identifiers and similar values appear to Java to be 64-bit values on all platforms, rather than changing between 32-bit and 64-bit values depending on the architecture. This allows the shared Java code in the JOGL X11 implementation to work on both 32- and 64-bit architectures, which is an important step toward having complete 64-bit support in JOGL. Compared to the suggested patch, there is no longer a need to duplicate the sources in net.java.games.jogl.impl.x11 because the Java sources are now 64-bit clean. The change to use dlsym on Linux/AMD64 instead of glXGetProcAddressARB has been conditionalized under a run-time flag. Most of the build.xml and all of the GlueGen changes were incorporated unchanged. Thanks to the original authors of the patch for this work. At this point "ant linux.amd64" should build a working JOGL. However, it can not yet be incorporated into the distribution's platform- independent jogl.jar; in order to do this, the generation of the StructAccessors for the JAWT and some other X11 data structures by GlueGen will need to be conditionalized depending on the platform so that the 32-bit versions go in one directory, the 64-bit versions in another, and a run-time check is done to determine which version to instantiate. There are also a few remaining cleanups to generated glue code such as net.java.games.jogl.impl.x11.GLX.XGetVisualInfo(), which needs to be made platform-independent by calling the XVisualInfo.size() accessor rather than hardwiring in the size of the data structure (although the real solution will probably need to be more complicated since there will probably be two XVisualInfo implementations in the jar file). git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@190 232f8b59-042b-4e1e-8c03-345bb8c30851

* Bug fix from user GKW on the JOGL forums for problems reported by Kenneth Russel2004-08-035-81/+240
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | users in JOGL 1.1 betas where the code path for wglChoosePixelFormatARB (supporting full-scene antialiasing) was failing on older cards. The old drivers expect an OpenGL context to be current while the wglChoosePixelFormatARB and associated calls are being made, even though the documentation explicitly states that this is not necessary. GKW's fix creates a native window synchronously (independent of the AWT) and associates an OpenGL context with it which is used to choose pixel formats for other windows on the same GraphicsDevice. Upon VM shutdown, a native message pump is started which causes proper disposal of the native window and its OpenGL contexts. There is currently no bug ID associated with this fix, although it may be a component of completely addressing several open bugs. Also includes a bug fix from GKW and kbr for: Issue 98: Just 1st frame rendering on ATI Radeon This was a race condition between JOGL's automatic discovery that the ATI_WORKAROUND was needed and the creation of the first GLCanvas and associated Animator. The need for disabling the setRenderingThread optimization was computed too late, incorrectly locking out other threads (in particular, the AWT event queue thread) from performing rendering of the component. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@144 232f8b59-042b-4e1e-8c03-345bb8c30851

Issue 69: Error on window resize Issue 89: Losing Backbuffer when Resizing/Moving a window The primary change is to support handing off of the display() implementation to the AWT event queue thread via a new class called SingleThreadedWorkaround in the impl package. This was done to cause the AWT's reshape code to execute on the same thread as all other OpenGL rendering without changing the threading model (e.g., Animator and the ability to manually call display()) visible to the end user. This set of changes appears to work around the problems seen on ATI cards with random corruption when resizing animating windows due to multithreading bugs in the drivers. More testing by a larger community will confirm this fix. Currently the workaround is enabled by default on ATI cards. A secondary but related change is to properly destroy the OpenGL context when a heavyweight component is removed from its container. In order to implement the above workaround, it was necessary to override addNotify and removeNotify to properly track whether GLCanvases were realized; at that point it was a fairly small step to properly delete and recreate OpenGL contexts. The previous heuristics which attempted to determine when a heavyweight had been realized have been removed. A new demo, TestContextDestruction, exercises the new functionality. It does still appear to exhibit resource leaks, however; removing and re-adding the GLCanvas from its parent multiple times causes the system to eventually slow down significantly. More work is needed in this area. However, the demo does now execute as opposed to throwing an exception which was the previous behavior. The current code has been tested on Windows on NVidia hardware with all existing demos with the workaround both enabled and disabled, and on ATI hardware with the existing compatible demos with the workaround enabled. The new abstract method in GLContext, destroyImpl(), has been implemented but not yet tested on X11 and Mac OS X. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@132 232f8b59-042b-4e1e-8c03-345bb8c30851
