* Fixed Issue 274: GLException when GLJPanel (initially not visible) is made ↵Kenneth Russel2007-03-211-0/+33
| | | | | | | | | | | | | | | | | | | | | | | | | visible/showing Investigation revealed that the symptom was similar to what happens when one tries to create a new OpenGL context against an invalid HDC on Windows. Discussion with Chris Campbell from the Java 2D team indicated that in situations where the Java 2D OpenGL pipeline is using Frame Buffer Objects for its rendering, it is possible that its internal OpenGL context can be left current to the on-screen drawable, and it only has a valid device context for the brief period of time when its OpenGL context was being made current. This means that by the time JOGL's code got a chance to run, it did not have a valid HDC and therefore could not create its OpenGL context against it. The workaround, suggested by Chris, is to forcibly make the Java 2D context current against its internal "scratch" pbuffer, which can be done with the internal invokeWithOGLSharedContextCurrent method. Added this workaround and verified it fixes the problem with the user's test case. This issue will be fixed in a forthcoming Java SE 6 update release, hopefully 6u2. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1176 232f8b59-042b-4e1e-8c03-345bb8c30851

* Fixed Issue 275: Rendering bugs in TextRenderer Kenneth Russel2007-02-221-1/+38
| | | | | | | | | | | | | Fixed problem where during resizing of backing store for TextRenderer we were neglecting to unbind the old texture and bind the new one. This caused attempts to render with an invalid texture, which was probably the cause of crashes and definitely the cause of rendering artifacts. Fixed by calling endRendering() / beginRendering() appropriately on the underlying TextureRenderer during resizing of the backing store of the TextRenderer. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1148 232f8b59-042b-4e1e-8c03-345bb8c30851

* Fixed Issue 262: DRIHack problems with ATI and possibly other driversKenneth Russel2007-01-211-7/+2
| | | | | | | | | | | Added support to GlueGen's NativeLibrary class for relative library path names which do not require expansion; for example, "libGL.so.1". Changed the DRIHack to first attempt to open libGL.so.1 instead of "GL", which expanded to "libGL.so". For some reason, this causes ATI's drivers to be picked up properly. Tested with various JOGL demos. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1093 232f8b59-042b-4e1e-8c03-345bb8c30851
* Added 3D rendering methods to TextureRenderer and TextRenderer on Kenneth Russel2007-01-202-90/+230
| | | | | | | | | | | | request of several people on javagaming.org forums. Refactored existing 2D rendering support in these classes in terms of the new 3D methods. Wrote new TextCube demo illustrating how to render 2D text in 3D using the TextRenderer. Factored out FPS counter rendering into new FPSCounter utility class and updated TestTextRenderer and FlyingText demos. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1092 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 260: "GLException: Surface already locked" after failed makeCurrent Kenneth Russel2007-01-173-12/+21
| | | | | | | | | Added checking for thrown run-time exceptions to on-screen GLContext makeCurrent() implementations on all three major supported platforms; now unlocks the underlying GLDrawable if an exception is thrown. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1088 232f8b59-042b-4e1e-8c03-345bb8c30851
* Robustness improvements to TextRenderer and underlying RectanglePacker. Kenneth Russel2007-01-135-84/+450
| | | | | | | | | | | | | | | Added ability to specify a maximum size to which the RectanglePacker can expand. Added preExpand method to BackingStoreManager to support early eviction of unused entries instead of always expanding the backing store, and additionFailed method used when the backing store can not expand further. Added more robust free list coalescing to Level. Added support for shrinking of backing store and for eager compaction when there is a lot of vertical dead space. Added TextFlow demo which shows how to do dynamic layout of text and which acts as a stress test for the TextRenderer. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1083 232f8b59-042b-4e1e-8c03-345bb8c30851

* Fixed Issue 259: need a copy context Kenneth Russel2007-01-075-0/+83
| | | | | | | | | | Added and specified GLContext.copy() and supplied implementations on Windows, X11 and Mac OS X platforms. New code is untested at this time. May need to make subsequent changes on X11 and Mac platforms where new code has not been compiled yet. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1075 232f8b59-042b-4e1e-8c03-345bb8c30851
* Added new FlyingText demo to illustrate more advanced usage of the Kenneth Russel2007-01-072-15/+34
| | | | | | | | | | | TextRenderer class; displays dynamically rotated, translated and colored text. Changed how setSmoothing() is handled by the TextureRenderer and stopped disabling smoothing in the TextRenderer. For the time being, not exposing this flag in that class to keep the API simple. Changed TextRenderer to also push/pop the texture matrix. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1073 232f8b59-042b-4e1e-8c03-345bb8c30851
* With help from Chris Campbell, fixed incredibly stupid bug on my part Kenneth Russel2007-01-063-1/+47
| | | | | | | | | | | | | | | | where the new Java 2D TextureRenderer was destroying and re-creating the OpenGL texture every frame. This was why the Java 2D Overlay class was so expensive, and why the TextRenderer wasn't as fast as it seemed it should be. Fixed bugs in all of the Java 2D demos which were covered up by this implicit sync, as well as in the TextRenderer class itself where it was missing a key sync operation. Added code to the Texture.updateSubImage() implementation to clip the incoming rectangle to the bounds of the input data and texture, to keep OpenGL from dropping almost-valid updates on the floor. Ran all of the Java 2D integration demos to verify these fixes. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1071 232f8b59-042b-4e1e-8c03-345bb8c30851
* With extensive help from Phil Race and Chris Campbell from the Java 2D Kenneth Russel2007-01-049-5/+1476
| | | | | | | | | | | | | | | | | | | | | | team, added a TextRenderer class which enables high-performance rendering of bitmapped Java 2D fonts, with full Unicode support, into arbitrary OpenGL drawables using a simple API. Builds on top of the TextureRenderer class and its associated functionality; added createAlphaOnlyRenderer() and other methods to enable the TextRenderer. Caches rendering results on a string-by-string basis in an OpenGL texture using a fully automatic least-recently-used algorithm for good efficiency when rendering the same string or strings multiple times. Uses a rectangle packing algorithm, currently housed in com.sun.opengl.impl.packrect, for managing the positions of cached strings on a larger OpenGL texture to avoid OpenGL pipeline state changes. Added a TestTextRenderer demo which simply adds a moving text string and frames-per-second counter to the Gears demo; more sophisticated examples to come. (Some commented-out debugging code is being temporarily left in the new demo, to be removed in the next checkin, in order to have it in the version history.) git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1067 232f8b59-042b-4e1e-8c03-345bb8c30851
* Moved J2DTextureRenderer and J2DOverlay into their own sub-package and Kenneth Russel2007-01-042-11/+11
| | | | | | | | | dropped the prefixes on the suggestion of Chris Campbell. No other changes to these classes. Added com.sun.opengl.util.j2d to the javadoc generation. Updated demos. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1066 232f8b59-042b-4e1e-8c03-345bb8c30851

* On request from James Gosling and others, added a J2DTextureRenderer Kenneth Russel2006-12-302-0/+559
| | | | | | | | | | | | | | | | | | class to com.sun.opengl.util to make it easier to render into OpenGL textures using Java 2D. Added convenience methods to this class to make it easy to draw sub-rectangles of the resulting texture to the screen. Added a J2DOverlay class which acts like a Java 2D-based heads-up display for an arbitrary GLDrawable, tracking its size and making it easier to render the entire contents of the HUD. There appear to be performance issues with the J2DOverlay class as the window gets large, at least on older hardware, as it allocates very large OpenGL textures internally. Added tests for both the J2DTextureRenderer and J2DOverlay classes which have similar functionality but different implementation approaches and different performance characteristics. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1059 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 257: RFE: Texture.updateSubImage(x,y,w,h) Kenneth Russel2006-12-292-143/+233
| | | | | | | | | | | | | | | | | | | | Changed TextureIO's BufferedImage code paths to no longer copy the data in order to correct for the vertical flip needed between Java 2D's and OpenGL's coordinate systems, but instead to correct for this using a flip of the texture coordinates. This was needed to change the semantics for the BufferedImage from "by-copy" to "by-reference". Made the custom BufferedImage copying code path occur lazily upon a call to TextureData.getBuffer(). Added support for the GL_EXT_abgr extension but disabled the code path currently as it appears there may be bugs in its support on some drivers. Added computation of row width for all BufferedImage types with help and suggestions from Chris Campbell. Improved handling of some BufferedImage types like TYPE_INT_ARGB and TYPE_4BYTE_ABGR. Added Texture.updateSubImage() taking a source rectangle as well as a destination coordinate. Wrote TestSubImage test to show use of the new API which exercises all BufferedImage types. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1057 232f8b59-042b-4e1e-8c03-345bb8c30851

* Fixed another performance problem related to buffer objects pointed Kenneth Russel2006-11-264-1/+412
| | | | | | | | | | | | | out by John Burkey. glGetBufferParameterivARB call in glMapBuffer was too expensive at least with Apple's multithreaded OpenGL implementation. Now track both bound buffer state (refactored into GLBufferStateTracker) as well as cache created buffers' sizes (expressed in GLBufferSizeTracker) and query the cache instead of OpenGL directly. Verified with VertexBufferObject demo that now no glGet queries are made at run-time. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1003 232f8b59-042b-4e1e-8c03-345bb8c30851
* Optimized buffer binding checks for glVertexPointer and similar calls Kenneth Russel2006-11-241-19/+32
| | | | | | | | | | | | | | on request from John Burkey. Now caches the buffer binding for GL_ARRAY_BUFFER, etc. upon glBindBuffer calls and invalidates this cache upon glPushClientAttrib / glPopClientAttrib calls, refreshing the state only when necessary using the glGetIntegerv call. Fixed knowledge of available OpenGL versions to support OpenGL 2.1 (and future minor version updates). Fixed breakage of GL_NV_vertex_array_range support after recent upgrade of wglext.h and glxext.h headers. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@994 232f8b59-042b-4e1e-8c03-345bb8c30851
