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 --- .../config/jogl/gl-impl-CustomJavaCode-common.java | 53 ++++++++++++++++------ 1 file changed, 40 insertions(+), 13 deletions(-) (limited to 'make/config/jogl/gl-impl-CustomJavaCode-common.java') diff --git a/make/config/jogl/gl-impl-CustomJavaCode-common.java b/make/config/jogl/gl-impl-CustomJavaCode-common.java index d552bc6e4..b05ba2643 100644 --- a/make/config/jogl/gl-impl-CustomJavaCode-common.java +++ b/make/config/jogl/gl-impl-CustomJavaCode-common.java @@ -1,48 +1,57 @@ + @Override public GLProfile getGLProfile() { return this.glProfile; } private final GLProfile glProfile; - public int glGetBoundBuffer(int target) { + @Override + public final int glGetBoundBuffer(int target) { return bufferStateTracker.getBoundBufferObject(target, this); } - public long glGetBufferSize(int buffer) { + @Override + public final long glGetBufferSize(int buffer) { return bufferSizeTracker.getDirectStateBufferSize(buffer, this); } - public boolean glIsVBOArrayEnabled() { + @Override + public final boolean glIsVBOArrayEnabled() { return checkArrayVBOEnabled(false); } - public boolean glIsVBOElementArrayEnabled() { + @Override + public final boolean glIsVBOElementArrayEnabled() { return checkElementVBOEnabled(false); } + @Override public final boolean isGL() { return true; } + @Override public final GL getGL() throws GLException { return this; } - public boolean isFunctionAvailable(String glFunctionName) { + @Override + public final boolean isFunctionAvailable(String glFunctionName) { return _context.isFunctionAvailable(glFunctionName); } - public boolean isExtensionAvailable(String glExtensionName) { + @Override + public final boolean isExtensionAvailable(String glExtensionName) { return _context.isExtensionAvailable(glExtensionName); } - public Object getExtension(String extensionName) { + @Override + public final Object getExtension(String extensionName) { // At this point we don't expose any extensions using this mechanism return null; } - /** Returns the context this GL object is associated with for better - error checking by DebugGL. */ - public GLContext getContext() { + @Override + public final GLContext getContext() { return _context; } @@ -51,18 +60,36 @@ /** * @see javax.media.opengl.GLContext#setSwapInterval(int) */ - public void setSwapInterval(int interval) { + @Override + public final void setSwapInterval(int interval) { _context.setSwapInterval(interval); } /** * @see javax.media.opengl.GLContext#getSwapInterval() */ - public int getSwapInterval() { + @Override + public final int getSwapInterval() { return _context.getSwapInterval(); } - public Object getPlatformGLExtensions() { + @Override + public final Object getPlatformGLExtensions() { return _context.getPlatformGLExtensions(); } + @Override + public final int getBoundFramebuffer(int target) { + return _context.getBoundFramebuffer(target); + } + + @Override + public final int getDefaultDrawFramebuffer() { + return _context.getDefaultDrawFramebuffer(); + } + + @Override + public final int getDefaultReadFramebuffer() { + return _context.getDefaultReadFramebuffer(); + } + -- cgit v1.2.3
