* Bug 801: Fix 183e1bc1868699b99eb9f9c8bf18d646d1120a48 'window box' CalculationSven Gothel2014-03-052-30/+24
| | | | | | | | | | | | Commit 183e1bc1868699b99eb9f9c8bf18d646d1120a48 only mapped object's bbox max/min points to window space, which is wrong due to possible rotation in 3d space. This commit adds AABBox.mapToWindow(..) method, which correctly either uses 4 points of the bbox in 3d space (using center-z) or all 8-points and creating a new bounding box. The resulting width and height of this window bbox gives the maximum amount of rectangular pixels for AA.

* Bug 801: Refine 'blend' usage and modes (API-doc and demo-code)Sven Gothel2014-03-053-4/+2
| | | | | | | | | | | | | - RegionRenderer: Make 'blend' setup pluggable via new GLCallbacks - 'GLCallback's for enable/disable, passed via 'create' method. Add 'defaultBlendEnable' and 'defaultBlendDisable', replacing previos fixed calls. - GLRegion.draw(..) added API-doc notes about: - Decorating call with RegionRenderer.enable(..) - glClearColor impact and blending - VBORegion2P*: Remove fixed glClearColor(..) call
* Bug 801: Fix VBAA Distortions (VBO-size fractional delta) and AA (Sample ↵Sven Gothel2014-03-049-266/+419
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fragment position and count) Inflating the FBO pixel-size of the region using a 'samples count' multiplier to the projected window bounding box allows controlling the AA distortion as well as defining the fragment position due to it's grid-fitting nature, see below. - Fix VBAA Distortions (FBO-size fractional delta) Inflated framebuffer exceeds 'box-size * sampleCount' since it must be the ceiling of the latter due to it's integer number nature. This difference either must reflect the texture-coords -or- the texture bounding vertices-box in the 2nd pass, otherwise a distorion will appear which is quite visible explicit w/ text. Using texture-coords is not suitable, due to floating point accuracy, hence this patch extends the texture bounding vertices-box about the ceiling delta. A comparible distortion existed with the previous implementation as well, since it used an arbitrary FBO-size and hence the magnification was not grid-fitting. Current implementation is grid-fitting, or at least matches the non-inflated grid, since it inflates the original window-size of the region about samples-count. - AA (Sample fragment position and count) Using a sample-count w/ a multiple of 2 (currently 2, 4 and 8 are properly implemented), based on the projected window bounding box will give the 2nd-pass fragment shader (AA) a fragment-postion in center of the sample pixels exposing one AA pixel. Hence we need to use the diagonal coords (NW, SW, ..) off by half a pixel to reach the 1st sample-pixel .. and 1.5 pixels to reach the 2nd .. and so forth.

* Bug 801: Fix TypecastRenderer End-Of-Contour and Shape-Closing; add cubic pathSven Gothel2014-02-281-46/+81
| | | | | | | | | | | | | | | | | | | | | | | - Fix TypecastRenderer End-Of-Contour (EOC) - Iterate through contour block up-until EOC-1, not trying to create a new 'path' from EOC. - Add cubic path - Detect a cubic path and use it, i.e. on-off-off-on - Fix Shape-Closing - Close shape at head, not tail, since we add vertices from the head. - Misc - addShape*(..) uses Point parameter 'onCurve' field reflecting proper handling. Status: Ubuntu Font: No artifacts Lucida: Removed all artifacts, but for character 'M' !? - No odd MID point - Maybe inside-outside (inner) detection is buggy ?

The former renders vertices dirty. - Region - Make triangles / vertices accessible - Add 'validateIndices()' to add indices for triangles, code moved from the GLRegion* impl. Shall be refined later! - GLRegion - Passing 'RegionRenderer' instead of RenderState .. reducing argument numbers and aligning all related 'render' methods while giving association to the RegionRenderer. - Renderer -> RegionRenderer, dropping 'intermediate' RegionRenderer - Dropping draw() in RegionRenderer, should be issued simply by GLRegion in a unique fashion. - Dropping RegionFactory Too simple code as-is, simply invoke in Region.create(..) - Overall: - Add 'final' qualifier - Remove overloaded methods where rither default args can be used or a followup method call completes the 'intention'.
* Bug 802: Graph TextRenderer Performance Part-1 (incomplete, rendering artifacts)Sven Gothel2014-02-2412-544/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Strategy Change: - Font.Glyph itself holds it's OutlineShape with it's default scaling. Triangulation is done only once per glyph! - A CharSequence produces a Region by translating and scaling each Glyphs's OutlineShape. This removes the need for re-triangulate - see above. See: TextRendererUtil - The indices of re-added Triangles are offset to the new vertices (FIXME, seems not be be accurate yet). - OutlineShape's vertices and triangles are reused if 'clean'. - Simplified code - Reduced copies API Changes: - OutlineShape, Region, ...: See above - Removed TextRenderer, GlyphShape and GlyphString: Redundant - Added TextRendererUtil to produce the Region from CharSequence Result: - Over 600 fps while changing text for each frame. Previously only ~60fps max. TODO: - Region shall not hold the triangles itself, but the indices instead. This will remove the need to swizzle w/ vertices in the Region Renderer impl and easies reusage of OutlineShapes.

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
