Seamless Integration of an FBObject based GLFBODrawable as GLOffscreenAutoDrawable.FBO and as an OffscreenLayerSurface's drawable (OSX) - Fix Bugs 569 and 599
Summary: ========= The new FBObject based GLFBODrawable implementation allows the seamless utilization of FBO offscreen rendering in single buffer, double buffer and MSAA mode. The GLFBODrawable uses a parent drawable based on a dummy surface to allow a GLOffscreenAutoDrawable.FBO creation or a mutable surface supporting an existing offscreen layer surface (OSX CALayer). Offscreen GLDrawable's and GLOffscreenAutoDrawable's can be selected via the GLCapabilities. If simply !onscreen is selected in the caps instance w/o enabling FBO, PBuffer or Bitmap, the factory will automatically choose regarding availability: FBO > PBuffer > Bitmap Double buffering is supported in MSAA more (intrinsic) and explicit in non MSAA. It is preferred when delivering resources (texture id's or framebuffer names) to a shared GLContext. This is demonstrated in (emulates our OSX CALayer implementation): TestFBOOffThreadSharedContextMix2DemosES2NEWT, TestFBOOnThreadSharedContext1DemoES2NEWT and with the OSX JAWT OffscreenLayerSurface itself. FBO is the preferred choice. +++ Offscreen drawables can be resized while maintaining a bound GLContext (e.g. w/ GLAutoDrawable). Previously both, drawable and context, needed to be destroyed and recreated at offscreen resize. Common implementation in GLDrawableHelper is used in the implementations (NEWT's GLWindow, AWT GLCanvas, SWT GLCanvas). +++ Tested: ======= Manually run all unit tests on: - Linux x86_64 NVidia/AMD/Mesa3d(ES) - OSX x86_64 NVidia - Windows x86_64 NVidia - Android arm Mali-400/Tegra-2 No regressions. Disclaimer: =========== This feature is committed almost in one patch. Both previous commits were introducing / fixing the capabilities behavior: 90d45928186f2be99999461cfe45f76a783cc961 9036376b7806a5fc61590bf49404eb71830de92f I have to appologize for the huge size and impact (files and platforms) of this commit however, I could not find a better way to inject this feature in one sane piece. NativeWindow Details: ===================== Complete decoupling of platform impl. detail of surfaces implementing ProxySurface. Used to generalize dummy surfaces and EGL surfaces on top of a native platform surface. - ProxySurface.UpstreamSurfaceHook -> UpstreamSurfaceHook - abstract class ProxySurface -> interface ProxySurface + ProxySurfaceImpl - Misc. implementations JOGL Details: ===================== FBOObject: API Change / Simplification & Usability - Removed reference counter to remove complexity, allow user to choose. - Add 'dispose' flag for detachColorbuffer(..), allowing to keep attachment alive - Fix equals operation of Attachment - Check pre-exising GL errors - Interface Colobuffer gets lifecycle methods - Add static factory methods to create Attachments w/o FBObject instance - Reset: - Clip min size to 1 - Keep alive samplingSink, i.e. don't issue resetMSAATexture2DSink(..). It gets called at syncFramebuffer()/use(..) later on before actual usage. This allows the consumer to utilize the GL_FRONT buffer until (e.g.) swap. - misc bugfixes GLOffscreenAutoDrawable: API Change - Reloc and interfacing - class com.jogamp.opengl.OffscreenAutoDrawable -> javax.media.opengl.* interfaces GLOffscreenAutoDrawable extends GLAutoDrawable GLOffscreenAutoDrawable.FBO extends GLOffscreenAutoDrawable, GLFBODrawable - Added general implementation and FBO specialization - Replacing GLPBuffer (deprecated) .. usable for any offscreen GLDrawable via factory GLAutoDrawable: - Add 'GLDrawable getDelegatedDrawable()' - Refine documentation of setContext(..), remove disclaimer and fixme tags GLDrawableFactory: - Refine API doc and it's selection mechanism for offscreen. - Add createOffscreenDrawable(..) - Add createOffscreenAutoDrawable(..) - Add canCreateFBO(..) - Mark createGLPbuffer(..) deprectated Mark GLPBuffer deprecated New: GLFBODrawable extends GLDrawable GLCanvas (AWT and SWT): Add offscreen resize support w/o GLContext recreation GLAutoDrawableBase .. GLWindow: - Add offscreen resize support w/o GLContext recreation - Remove double swapBuffer call - GLBase/GLContext: - Add: - boolean hasBasicFBOSupport() - boolean hasFullFBOSupport() - int getMaxRenderbufferSamples() - boolean isTextureFormatBGRA8888Available() GLContext: Fix version detection and hasGLSL() - Version detection in setGLFunctionAvailability(..) - Query GL_VERSION ASAP and parse it and compare w/ given major/minor - Use parsed version if valid and lower than given _or_ given is invalid. - Use validated version for caching (procaddr, ..), version number, etc. - Fix hasGLSL() Since 'isGL2ES2()' is true if 'isGL2()' and the latter simply alows GL 1.*, we confine the result to a GL >= 2.0 on desktops. FIXME: May consider GL 1.5 w/ extensions. - return isGL2ES2(); + return isGLES2() || + isGL3() || + isGL2() && ctxMajorVersion>1 ; GLDrawableImpl: - Add 'associateContext(GLContext, boolean)' allowing impl. to have a (weak) reference list of bound context. This is was pulled up from the OSX specific drawable impl. - swapBuffersImpl() -> swapBuffersImpl(boolean doubleBuffered) and call it regardless of single buffering. This is required to propagate this event to impl. properly, i.e. FBODrawable requires a swap notification. - Clarify 'contextMadeCurrent(..)' protocol GLDrawableHelper: - Add resize and recreate offscreen drawable util method - Simplify required init/reshape calls for GLEventListener - GLGraphicsConfigurationUtil: - fixWinAttribBitsAndHwAccel: Reflect sharede context hw-accel bits - OSX has no offscreen bitmap, use pbuffer - use proper offscreen auto selection if offscreen and no modes are set EGL Context/Drawable/DrawableFactory: Abstract native platform code out of base classes - Use EGLWrappedSurface w/ UpstreamSurfaceHook to handle upstream (X11, WGL, ..) lifecycle - in case the EGL resource is hooked up on it. Invisible dummy surfaces: All platforms - size is now reduced to 64x64 and decoupled of actual generic mutable size - fix device lifecycle, no more leaks +++ OSX ==== Enable support for GLFBODrawableImpl in offscreen CALayer mode - NSOpenGLImpl: hooks to calayer native code - calayer code: - allows pbuffer and texures (FBO) - decouple size and draw calls avoiding flickering - enable auto resize of calayer tree MacOSXCGLContext: - NSOpenGLImpl: - Fix false pbuffer 'usage', validate the pointer - If !pbuffer, copy other window mode bits of caps - MacOSXCGLGraphicsConfiguration: - Only assume pbuffer if !onscreen - Remove reference of native pixelformat pointer Native code: - use 'respondsToSelector:' query before calling 'new' methods avoiding an error message where unsuported (prev. OSX versions) - if monitor refresh-rate is queried 0, set to default 60hz - add missing NSAutoreleasePool decoration +++ Android / NEWT: =============== Issue setVisible(..) w/o wait, i.e. queue on EDT, @Android surfaceChanged() callback. Otherwise we could deadlock: setVisible(..) -> EDT -> setVisibleImpl(..) -> 'GL-display'. the latter may may cause havoc while Android-EDT is blocked [until it's return].
