- New FBObject implementation handling FBO and it's attachments *** API CHANGE: Util -> Core ***
while it's size and sample-count can be reconfigured on the fly.
- com.jogamp.opengl.util.FBObject -> com.jogamp.opengl.FBObject
- agnostic to texture unit
- separate attachments using OO hierarchy reflecting FBO
- handling MSAA and blitting
- no FBO destruction for reconfig (attach/detach)
- New GLFBODrawableImpl impl. an FBObject based GLDrawable
- Instantiated by a dummy native surface (onscreen and invisible)
hooked up to a dummy GLDrawable, which is the delegation for context creation.
- Utilizies ProxySurface.UpstreamSurfaceHook for dummy surface
avoiding specialization for native platforms.
- TODO: Allow to utilize common surface interface as a
dummy-surface to supporting API seperation of
windowing/GL. The latter allows impl. of createGLDrawable(NativeSurface)
with FBO.
- New OffscreenAutoDrawable (extends GLAutoDrawableDelegate)
for all offscreen drawables. Shall replace GLPbuffer.
- New GLCapabilities*.isFBO() / setFBO(boolean) to request FBO offscreen,
similar to isPBuffer(). Rule: if both are requested, FBO shall be favored.
- GLContext adds raw FBO availability query (min. FBO avail),
FBObject contains fine grained queries (TODO: Move parts to GLContext for efficiency).
- Add framebuffer tracking, allowing fast querying:
- GLBase/GLContext:
public int getBoundFramebuffer(int target);
public int getDefaultDrawFramebuffer();
public int getDefaultReadFramebuffer();
- GLContextImpl
public final void setBoundFramebuffer(int target, int framebufferName)
.. called by GL impl bind framebuffer
- GL: getDefaultDrawFramebuffer(), getDefaultReadFramebuffer()
Adding default framebuffer queries being issued by
GL.glBindFramebuffer(target, 0) w/ a default framebuffer, o.e. zero.
This allows a transparent use of a custom FBO even in case the applications
attempts to reset FBO to zero.
Value flow: GL <- GLContext <- GLDrawable,
- GLCapabilities handle fbo/pbuffer seperate, don't disable the other
- GLContext/GL track read/write framebuffer to be queried by FBObject
to determine whether to bind/unbind a framebuffer
- Test cases for multiple FBO w/ and w/o MSAA
Other Features:
- New interface ProxySurface.UpstreamSurfaceHook,
allowing to hook an upstream surface of unknown type
providing lifecycle and information (size, ..) callbacks.
Used for all new dummy NativeSurface impl and SWT GLCanvas.
- GLContext -> GLDrawable propagation context/drawable lifecycle
via ProxySurface.UpstreamSurfaceHook allowing dynamic resources
to react (create, init, ..)
- contextRealized()
- contextMadeCurrent()
- SurfaceChangeable -> MutableSurface
currently only contains setting the surface handle.
TODO: May need to move ProxySurface.UpstreamSurfaceHook -> MutableSurface.UpstreamSurfaceHook,
allowing other impl. classes (NEWT OffscreenWindow) to utilize the new
upstream hookup mechanism - will allow FBO/Dummy window to work.
- SWT GLCanvas using ProxySurface.UpstreamSurfaceHook for proper size
propagation.
- New GLAutoDrawable::getUpstreamWidget(), allowing GLEventListener
to fetch the owning Java side UI element (NEWT, SWT, AWT, ..).
- GLDrawableFactory: Removed createOffscreenSurface() - unused and not GL related
- EGLDrawableFactory handles device/profile avail. mapping
while actually creating context/drawable.
This allows us to learn whether the ES context is software/hardware as well as FBO avail.
- EGLDrawable: Removed secret buckets of EGL configs :)
Employ native surface (X11, WGL, ..) to EGL 'mapping' in
EGLDrawableFactory utilizing new EGLUpstreamSurfaceHook (implements ProxySurface.UpstreamSurfaceHook).
Other Bugs:
- Add CTX_OPTION_DEBUG to ctx/extension cache key since only a debug ctx
may expose the ARB debug capability.
This bug caused lack of ARB/AMD debug functionality.
- Fix GLProfile deadlock (debug mode, w/ EGL/ES, no X11),
dump availability information _after_ lock.
- ImmModeSink draw(): Use GL's glDrawElements(..), don't cast for GL2ES1.
Fixes use for GL2ES2.
- Fix KeyEvent.getKeyChar() comment (-> only stable for keyTyped(..))
Misc:
- Refined alot of API doc
- New GLExtensions holds commonly used GL extension strings,
allows better referencing and usage lookup.
- Move GL (interface) decl. to GLBase
- GLBuffers: Cleanup API doc (format, types)
- TextureIO: Add PAM and PPM static suffix identifier
- GLCapabilities getNumSamples() returns 0 if sampleBuffers is disabled, this seems to be more natural.
- finalized a lot

GLProfile and GLContext*
GLProfile: Enhance bootsrapping performance of loading GL*Impl class
- Offthread classloading of all GL*Impl via reflection at startup
reduces startup time here around 12% (800ms down to 700ms).
GLContext*: Enhance bootsrapping performance of querying available GL profiles
- Add PROFILE_ALIASING mode, defaults to true - can be disabled w/ property 'jogl.debug.GLContext.NoProfileAliasing'
- PROFILE_ALIASING:
If true (default), bootstrapping the available GL profiles
will use the highest compatible GL context for each profile,
hence skipping querying lower profiles if a compatible higher one is found.
Linux x86_64 - Nvidia: 28%, 700ms down to 500ms
Linux x86_64 - AMD : 40%, 1500ms down to 900ms
- GL*Impl:
- make fields final: glProfile, _context, buffer*Tracker and glStateTracker
- allow null _context/glProfile in initialization (bootstrapping)
- JoglVersion.getDefaultOpenGLInfo(..)
- add arg: 'boolean withCapabilitiesInfo', allowing to suppres the list of caps

and desktop (undefined).
*GLContext.setSwapIntervalImpl: Simple return success, set state in GLContext.

- Subsume GL_EXT_texture_format_BGRA8888 -> GL,
Added GLContext.isTextureFormatBGRA8888Available()
- Movied generic isNPOTTextureAvailable() from GL -> GLContext, used by GL (desktop),
added simplified impl. in GLES1/GLES2 (false/true)

- GLProfile properly detects native EGL/ES1/ES2 on the 'desktop' device factory.
This allows usage of Mesa's EGL/ES or Imageon's PVR emulation, etc.
- GLProfile drops getDefaultDesktopDevice() and getDefaultEGLDevice()
since both are aligned by getDefaultDevice().
- Fix GL_ARB_ES2_compatibility detection and utilize
resulting isGLES2Compatible() where possible.
This allows ES2 compatible desktop profiles to use core ES2 functionality
(glShaderBinary() .. etc) even with a GL2ES2 desktop implementation.
- EGLDrawable: If createSurface(..) fails (BAD_NATIVE_WINDOW) w/ surfaceHandle
it uses windowHandle if available and differs.
This allows the ANGLE impl. to work.
- Properly order of EGL/ES library lookup:
ES2: libGLESv2.so.2, libGLESv2.so, GLES20, GLESv2_CM
EGL: libEGL.so.1, libEGL.so, EGL
- *DynamicLookupHelper reference will be null if it's library is not complete
(all tool libs, all glue libs and a ProcAddressFunc lookup function - if named).
- Enhance GL version string (incl. ES2 compatible, hw/sw, ..)
- GLBase: Fix docs and remove redundancies
- Prepared (disabled) DesktopES2DynamicLibraryBundleInfo
to be used for a real EGL/ES2 implementation within the desktop GL lib (AMD).
Sadly it currenly crashed within eglGetDisplay(EGL_DEFAULT_DISPLAY),
hence it's disabled.

- All available OpenGL versions (native/platform) are verified at GLProfile
initialization and can be queried ..
A mapping of major,compat -> major,minor,options is created.
- Removal of temp context creation, when creating a context.
This was necessary to query general availability of ARB_create_context.
Due to the shared context of X11GLXDrawableFactory and WindowsWGLDrawableFactory,
this is no more necessary.
Due to the version mapping, the ARB_create_context paramters are known.
- NativeWindow X11Lib: Added X11ErrorHandler, throwing a RuntimeException.
Necessary to catch BadMatch .. etc X11 errors, eg for glXCreateContextAttribsARB
Hence all X11 calls are covered now.
- X11DummyGLXDrawable needs to use an own Window, otherwise GLn n>2 fails
- Flattening the desktop GL* implementation,
all use GL4bcImpl, which reduces the footprint dramatically.
- GL*Impl.isGL*() (desktop) utilizes the GLContext.isGL*(),
hence the results reflect the actual native context version.
- GLContextImpl makeCurrent/create: Added workflow documentation,
clarified code, defined abstract methods to have a protocol.
- Removed moved files (from here to gluegen),
see gluegen a01cb3d59715a41153380f1977ec75263b762dc6
- NativeLibLoader -> <TYPE>JNILibLoader
- Fixed Exception Handling (as in gluegen bce53b52c8638729750c4286dbc04cb14329fd34),
ie removed empty catch Throwable ..
- GLContext.setSwapInterval(): Nop in offscreen case, otherwise X11IOError (NVIDIA Bug)
Test:
Tests
- Junit
- demos.gears.Gears
- demos.jrefract.JRefract
Platforms
- Linux 64/32 ATI/NVidia
- MacOsX
- Windows (virtualbox 3.1.6, offscreen failed)
TODO/BUGS:
- FIXME ATI GLn n>2 with AWT, can't make context current, works well on NVIDIA though
- FIXME GL3GL4: Due to GL3 and GL4 implementation bugs, we still choose GL2 first, if available!
- Add GL 3.3 to GL3/gl3ext.h
- Add GL 4.0 to GL3/gl3ext.h and fix the GL3/GL4 seperation
- Rename jogl.gl2.jar -> jogl.gldesktop.jar (as done with it's native lib already)
