From 20bf031db719f7baa4c6e74734fc999061e08fe2 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Thu, 19 Jul 2012 21:15:10 +0200 Subject: Bug 599 - FBObject / Offscreen Support - Part 1 - 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 --- src/jogl/classes/jogamp/opengl/GLDrawableImpl.java | 47 +++++++++++++++++++++- 1 file changed, 45 insertions(+), 2 deletions(-) (limited to 'src/jogl/classes/jogamp/opengl/GLDrawableImpl.java') diff --git a/src/jogl/classes/jogamp/opengl/GLDrawableImpl.java b/src/jogl/classes/jogamp/opengl/GLDrawableImpl.java index 58a4ac6b4..abf2bf557 100644 --- a/src/jogl/classes/jogamp/opengl/GLDrawableImpl.java +++ b/src/jogl/classes/jogamp/opengl/GLDrawableImpl.java @@ -42,6 +42,7 @@ package jogamp.opengl; import javax.media.nativewindow.AbstractGraphicsDevice; import javax.media.nativewindow.NativeSurface; +import javax.media.nativewindow.ProxySurface; import javax.media.opengl.GLCapabilitiesImmutable; import javax.media.opengl.GLContext; import javax.media.opengl.GLDrawable; @@ -75,7 +76,7 @@ public abstract class GLDrawableImpl implements GLDrawable { if( !realized ) { return; // destroyed already } - GLCapabilitiesImmutable caps = (GLCapabilitiesImmutable)surface.getGraphicsConfiguration().getChosenCapabilities(); + final GLCapabilitiesImmutable caps = (GLCapabilitiesImmutable)surface.getGraphicsConfiguration().getChosenCapabilities(); if ( caps.getDoubleBuffered() ) { if(!surface.surfaceSwap()) { int lockRes = lockSurface(); // it's recursive, so it's ok within [makeCurrent .. release] @@ -149,6 +150,9 @@ public abstract class GLDrawableImpl implements GLDrawable { realized = realizedArg; AbstractGraphicsDevice aDevice = surface.getGraphicsConfiguration().getScreen().getDevice(); if(realizedArg) { + if(surface instanceof ProxySurface) { + ((ProxySurface)surface).createNotify(); + } if(NativeSurface.LOCK_SURFACE_NOT_READY >= lockSurface()) { throw new GLException("GLDrawableImpl.setRealized(true): Surface not ready (lockSurface)"); } @@ -156,17 +160,21 @@ public abstract class GLDrawableImpl implements GLDrawable { aDevice.lock(); } try { - setRealizedImpl(); if(realizedArg) { + setRealizedImpl(); updateHandle(); } else { destroyHandle(); + setRealizedImpl(); } } finally { if(realizedArg) { unlockSurface(); } else { aDevice.unlock(); + if(surface instanceof ProxySurface) { + ((ProxySurface)surface).destroyNotify(); + } } } } else if(DEBUG) { @@ -175,6 +183,39 @@ public abstract class GLDrawableImpl implements GLDrawable { } protected abstract void setRealizedImpl(); + /** + * Callback for special implementations, allowing GLContext to trigger GL related lifecycle: construct, destroy. + *
