* GLRendererQuirks: Add RequiresBoundVAO (w/ impl.), GLSLBuggyDiscard (todo) ; ↵Sven Gothel2012-10-281-2/+9
| | | | | | | | | | | | | | | | GLContextImpl: Bind default VAO if having quirk RequiresBoundVAO. OSX w/ OpenGL >= 3 core context implementation requires a bound VAO for vertex attribute operations, i.e. VertexAttributePointer(..). This has been experienced on OSX 10.7.5, OpenGL 3.2 core w/ Nvidia GPU and in several forum posts. Such 'behavior' violates the GL 3.2 core specification, which does not state this requirement, hence it is a bug. (Please correct me if I am wrong!) GLContextImpl works around this quirk, by generating a default VAO and binds it at 1st makeCurrent (@creation) and deletes it at destroy. This is minimal invasive since no action is required for subsequent makeCurrent or release. We assume if a user uses and binds a VAO herself, she will mind this quirk. Note: We could enhance this workaround by quering for a currently bound VAO at makeCurrent() and bind our default if none. However, we refrain from this operation to minimize the workaround and complexity.

| | | | | | | | | All *Pointer methods used 'normalized:=false', but we cannot assume the fixed function code does use normalized (0f..1f) values. On the contrary, it usually uses the native format value range. Hence we have to pass normalized:=true for all fixed point data types and normalized:=false for floating point data types.

| | | | | | | | | | | | | | | | The readlong() method is attempting to build a 64bit value from two 32 bit reads. The problem is that shifting an int only uses the lower 5 bits of the shift value, so << 32 is the same as << 0. Cast to long and restore the original intention.

See fixed VBORegion* patch for use case, i.e. using a VBO index buffer for glDrawElements(). Complets commit 8582ece7dc7f65271b3184261697a542766d9864.

| | | | | | | | | | VBO: Always unbind VBO ASAP after data transfer (glBufferData()) and assignment (glVertexPointer(..), glVertexAttribPointer()). It's a bug to leave it bound .. due to redundancy and other calls which could have change the VBO binding.

(API Change) - Changed create*(..) factory methods (API Change) - Drop passing GL instance, not needed - allows creation of ImmModeSink as final field w/o GL context - Use 'glBufferUsage' to determine whether to use VBO or not ( 0 == glBufferUsage ) - Use glBufferUsage in glBufferData(..) call (oops) - Toggle vboUsage per object ( 0 == glBufferUsage ? nonVBO : VBO ) remove static VBO usage flag - Fix render mode - GL_POLYGON -> GL_TRIANGLE_FAN (not GL_LINES) - GL_QUADS -> Looped GL_TRIANGLE_FAN (is !GL2) in draw(..) w/ and w/o indices - Buffer usage - documented - allow creating sink w/ all components (vertices, color, normal and texCoords) bit render and grow only used parts. This allows proper usage of sink where it is not known which types are being used. - Added test case - Manually tested w/ Jake2 ES1 Jake2 uses the FFP immediate mode rendering, where we utilize this sink w/o rendering artifacts.

| | | | | | | | | | | | | | | | | | | Colorbuffer w/ diff size leads to GL_FRAMEBUFFER_UNSUPPORTED. This occured at least on: - OS X 10.6.8 - GL_RENDERER NVIDIA GeForce 7300 GT OpenGL Engine - GL_VERSION 2.1 NVIDIA-1.6.36 Remedy is to catch the exception @ GLFBODrawableImpl.reset(..) and switch over to fallback 'reset' method: FBO reattachment -> FBO complete recreation Of course, the FBO recreation is noticable slower, but at least it seems to work on the offending system. Not tested on the offending system, but manually provoked GLException on FBOObject to trigger fallback, which is working here.

This shall ensure a valid drawable after even a non AWT-EDT issued first setVisible(). - GLCanvas.reshape() only if drawble valid Otherwise offscreen reshape attempts would happen even on unrealized drawable, which is not necessary. - GLCanvas.validateGLDrawable() also test isDisplayable() To make sure the native peer is valid, also test isDisplayable() - Fix size validation Since we have experienced odd size like 0 x -41 test each component, i.e. 0 < width && 0 < height. This is done through all JOGL/NEWT components. - resizeOffscreenDrawable(..) don't validate 'safe' size 1x1 In case method is called w/ odd size, i.e. 0 x -41, the safe size 1x1 is used. However, we cannot validate this size. Dump WARNING if odd size is detected.

(Minor API change) Using bitmask for requested Mvi and Mvit matrices, same as dirty-bits to ease matching and update operation. Update of Mvi and Mvit will be performed only if it's dirty-bit and request-bit set within update(). The individual dirty bit is cleared only if it's matrix update is performed. Update is also issued at get-Mvi/Mvit-Matrix operations to ensure proper values w/o update call w/o clearing the modified-bits. update() returns true if the Mvi or Mvit matrix got updated _or_ one of the modified bits is set. update() clears the modified-bits. Adding explicit getModifiedBits() to get and clear it's state. Adding unit test. Lots of API docs ..

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 ..

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].
