* Refactored platform extensions out of the GL interface and Kenneth Russel2005-07-2714-203/+274
| | | | | | | | | | | | | | implementation and into their own objects according to the JSR-231 expert group's resolutions. Moved the interfaces declaring these extensions into the platform-specific implementation directories and added a loosely-specified GL.getPlatformGLExtensions(). This will shrink the size of the platform-independent jar file considerably as the implementing class for the public GL interface is now no longer replicated for each platform. The build process is also simplified a fair bit; more simplifications are possible. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/branches/JSR-231@337 232f8b59-042b-4e1e-8c03-345bb8c30851

| | | | | | | | | | Windows to be encapsulated in WindowsDummyGLDrawable class. This is a prerequisite for implementing top-level pbuffer support in the GLDrawableFactory (i.e., not associated with a GLCanvas). Refactored context implementations further on all platforms. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/branches/JSR-231@325 232f8b59-042b-4e1e-8c03-345bb8c30851
* Further context-related changes for the JSR-231 API. The GLContext Kenneth Russel2005-07-1740-2449/+3213
| | | | | | | | | | | | | | | | | | | | | | | implementations on all platforms have been split into orthogonal GLDrawable and GLContext concepts. It is now possible to create more than one GLContet per GLDrawable (though this has not been tested yet). GLCanvas has been reimplemented in terms of GLDrawableFactory.getGLDrawable(). More functionality has been moved from GLDrawable to GLAutoDrawable. Reimplemented lazy sending of reshape GLEventListener events in GLCanvas and GLJPanel and deleted notion of deferred reshapes from GLDrawableHelper and elsewhere. Sharing of textures and display lists is now expressed in terms of GLContexts instead of GLDrawables. Still need to move pbuffer creation into GLDrawableFactory from the onscreen GLContext implementations. Added option to gleem ExaminerViewer to disable automatic redraws upon mouse events and respecified more of gleem to work on GLAutoDrawables rather than GLDrawables. Updated all JOGL demos to work with new APIs and slightly different initialization sequences (in particular, for pbuffers -- this will change with the addition of GLDrawableFactory.createGLPbuffer()). git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/branches/JSR-231@324 232f8b59-042b-4e1e-8c03-345bb8c30851

* Initial set of context-related changes for the JSR-231 API. GLContext Kenneth Russel2005-07-1030-1302/+1070
| | | | | | | | | | | | | | | has been exposed in the public API. The GLEventListener callback mechanism has been removed from the core GLContext implementation and moved up to a higher level. GLAutoDrawable now contains the GLEventListener-related methods, and the GLEventListener's methods now receive a GLAutoDrawable as argument. All JOGL demos have been updated for the new APIs. Many FIXMEs and much unimplemented functionality remain. There is slightly different initialization behavior for the demos containing pbuffers, and the deferring of reshape callbacks needs to be rethought. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/branches/JSR-231@320 232f8b59-042b-4e1e-8c03-345bb8c30851

* Fixed Windows port after changes to GlueGen to include array offsets. Kenneth Russel2005-07-085-20/+68
| | | | | | | | | | | Ported all demos to new API. Temporarily added back in GLU entry points taking primitive arrays as the underlying APIs (in particular, glTexImage2D) do not yet support non-direct Buffers. Changed C code generation to only add in array offset if array is non-null. Fixed bug in GLU tesselator demo's vertex callback. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/branches/JSR-231@318 232f8b59-042b-4e1e-8c03-345bb8c30851

| | | | | | | | | | | | | | | | | | | | | | | | respected and used properly in all of the public and private functions. The changes are in gluegen, so that the code is generated properly. And also throughout the parts of the jogl code that are not gluegen-generated. For the internally generated implementation methods, a "1" is added to the method names. So as to not overload the public API. This is similar to what is already done with Buffer APIs, which have a "0" added internally. I used a "1" instead of a "0" to avoid any collisions of the signatures, which could happen if a null object was sent down for the Array (e.g., the wrong method would get called). This should be a suitable foundation for the implementation to add the ability to wrap arrays in Buffers, which we plan to add to the implementation soon. These changes will cause all existing JOGL programs to break, although adapting them is pretty easy. We will later be putting back changed examples and utilities that incorporate these new APIs. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/branches/JSR-231@313 232f8b59-042b-4e1e-8c03-345bb8c30851

This allows a setting of an internal Buffer object parameter and JOGL will start reading data at the point in the buffer to which this position is set * The code is now generated to always respect this offset option. This has the affect of changing the internal signatures of all methods that use Buffers. But it does not affect the external API at all. * Old JOGL programs will continue working the same as long as they had the Buffer position set to zero before (the default value) git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/branches/JSR-231@281 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
