* Fixed Issue 344: Serious TextRenderer problems involving large fonts & ↵Kenneth Russel2008-02-181-476/+462
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unicode characters The glyph-based rendering algorithm for the TextRenderer was performing rendering in two steps: glyph preparation and upload, and rendering. This structure doesn't work in the context of the RectanglePacker, which can reorganize the backing store during any upload. Restructured the glyph cache in the TextRenderer in terms of flyweight Glyph objects which know how to upload and render themselves. During any upload, the outstanding glyphs not yet rendered to the screen may thereby be flushed. Improved the code path which falls back to the string-by-string algorithm for complex Unicode characters so that incoming strings can be segmented into multiple parts which are rendered either using the glyph cache or the string-by-string algorithm. Also tinkered with the bounds of glyphs and strings on the backing store to try to more definitively eliminate bleed-over between adjacent characters on the backing store, and to ensure that all of the pixels of glyphs are drawn. Some heuristics are unfortunately involved but the new code appears to work well with both very large and very small fonts. Added a few more test cases for the TextRenderer based on the bug report. Tested with the previous test cases as well. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1533 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 342: demos/j2d/TextFlow (TextRenderer) demo gives fuzzy text Kenneth Russel2008-02-161-7/+32
| | | | | | | | Added setSmoothing / getSmoothing to TextRenderer API to offer control over filtering mode of the TextureRenderer backing store. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1528 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 339: Add system properties to turn off VAs/VBOs in TextRenderer Kenneth Russel2008-02-161-17/+80
| | | | | | | | | Incorporated patch from emzic, slightly modified, to add set/getUseVertexArrays() as concession to graphics cards which do not perform well with small vertex arrays. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1527 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 332: TextRenderer depends on OpenGL 1.3 glClientActiveTexture Kenneth Russel2007-11-151-1/+0
| | | | | | | | | | | Removed call to glClientActiveTexture, which was incorrect as written since the texture object was being bound to the current texture unit and then the active texture unit forced to GL_TEXTURE0 just before setting up the texture coordinate pointer. Tested with text demos in jogl-demos workspace. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1440 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 326: TextRenderer corruption with certain text Kenneth Russel2007-11-091-6/+19
| | | | | | | | | | | | | | | | | Fixed four issues: - Regression in new segmenting and punting code causing ArrayIndexOutOfBoundsException due to not resetting the glyph uploader during punt. - Issue in same code where length and total advance were not being reset properly. - Incorrect handling in glyph-by-glyph rendering when backing store was using NPOT texture and GL_ARB_texture_rectangle. - Failure to punt when glyph code was out of bounds. Checked in two regression tests for these issues. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1434 232f8b59-042b-4e1e-8c03-345bb8c30851
* Added RenderDelegate.getBounds(GlyphVector, FontRenderContext) and Kenneth Russel2007-11-031-6/+12
| | | | | | | | delegated to it in glyph-by-glyph renderer in order to support advanced RenderDelegates. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1424 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixes from John Burkey: Kenneth Russel2007-11-031-53/+117
| | | | | | | | | | | 1) Add segmenting for runs of glyphs that are going to blow the cache (we track upload size) a) upload handling b) glyph run segmenting 2) Fix incorrect assumption that the glyph cached didn't change size. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1423 232f8b59-042b-4e1e-8c03-345bb8c30851

* Made TextRenderer.DefaultRenderDelegate public and static on request Kenneth Russel2007-10-191-1/+1
| | | | | | | from emzic on JOGL forum git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1409 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 324: Rendering artifacts with glyph-based TextRenderer Kenneth Russel2007-10-171-1/+1
| | | | | | | | Changed from using getVisualBounds() to the more accurate getPixelBounds() when computing bounding box for individual glyphs. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1406 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 323: TextRenderer leaves VBOs bound Kenneth Russel2007-10-171-14/+39
| | | | | | | | | | | | | Manually unbound VBOs because it appears that some graphics drivers do not push and pop the GL_ARRAY_BUFFER_BINDING and other state during glPushClientAttrib / glPopClientAttrib. This is an area where the OpenGL specification is ambiguous. Added a non-VBO code path using normal vertex arrays for graphics cards that don't support VBOs. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1404 232f8b59-042b-4e1e-8c03-345bb8c30851

Bumped build number to 1.1.1-rc6. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1396 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed problems causing breakage of NASA's World Wind Java. Added need Kenneth Russel2007-10-101-0/+19
| | | | | | | | | glPush/PopClientAttrib due to modification of vertex array enable states and vertex buffer object bindings. Fixed bug in setColor() where flushing was not occurring every time it needed to. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1393 232f8b59-042b-4e1e-8c03-345bb8c30851
* Integrated John Burkey's new TextRenderer implementation using Kenneth Russel2007-10-091-172/+853
| | | | | | | | | | | | | | | | | | | | | glyph-by-glyph caching for most cases, with fallbacks to String-by-String caching for complete Unicode correctness. New implementation yields drastic performance improvements for applications displaying large amounts of dynamic text. Upgraded JOGL demos to work with new TextRenderer. This checkin fixes at least the following issues: Issue 261: Throttle shrinking of backing store texture for TextRenderer Issue 293: TextRenderer: width of strings with spaces not correct in RC4 Issue 294: TextRenderer: rendering stops when a string is wider than the maximum texture size Issue 304: TextRenderer rendering artifacts in 3D mode as well as outstanding performance issues with the current TextRenderer reported on the JOGL forum. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1388 232f8b59-042b-4e1e-8c03-345bb8c30851
* Cleaner version of previous fix. Clarified documentation, made the Kenneth Russel2007-05-171-13/+12
| | | | | | | | | default Composite SrcOver, and now save and restore the Composite just to avoid destroying any RenderDelegate's Composite unnecessarily (although there is no guarantee it will be preserved). git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1249 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed problem in TextRenderer where custom render delegates would Kenneth Russel2007-05-171-0/+8
| | | | | | | | | result in corrupted backing store due to semantics of Graphics.copyArea() paying attention to transparent pixels; need to clear out the destination rectangle first git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1248 232f8b59-042b-4e1e-8c03-345bb8c30851

* More fully debugged tokenized rendering of strings and turned it on by Kenneth Russel2007-04-081-13/+19
| | | | | | | | default. Can be disabled by specifying -Djogl.TextRenderer.nosplit. Exposed getSpaceWidth() on request of emzic on javagaming.org forums. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1195 232f8b59-042b-4e1e-8c03-345bb8c30851
* Added automatic mipmap generation support via GL_GENERATE_MIPMAP Kenneth Russel2007-04-082-15/+121
| | | | | | | | | | texture parameter to Texture class. Exposed this support up through the TextureRenderer and TextRenderer classes. Tested by temporarily enabling mipmap support for TextCube demo; no visual improvement, however, so left it disabled for now. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1194 232f8b59-042b-4e1e-8c03-345bb8c30851
* Added a markDirty() method to TextureRenderer and removed the sync() Kenneth Russel2007-03-273-25/+62
| | | | | | | | | | | method. markDirty() may be called at an arbitrary point (in particular, when no OpenGL context is current) and the union of the dirty regions is automatically synced with the underlying texture during the next getTexture() operation, at which point the dirty region is cleared. Adjusted Overlay and TextRenderer classes. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1182 232f8b59-042b-4e1e-8c03-345bb8c30851
* Made disabling of the depth test optional in TextRenderer and Kenneth Russel2007-02-272-12/+63
| | | | | | | | TextureRenderer's orthographic rendering methods based on feedback from Dave Collins from NASA World Wind project git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1160 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 278: Fatal error when rendering text Kenneth Russel2007-02-271-0/+40
| | | | | | | | | Added code to restore current text drawing color when backing store is resized. Fixed NullPointerException in RectanglePacker during deletion if no backing store was allocated. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1156 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 275: Rendering bugs in TextRenderer Kenneth Russel2007-02-221-1/+38
| | | | | | | | | | | | | Fixed problem where during resizing of backing store for TextRenderer we were neglecting to unbind the old texture and bind the new one. This caused attempts to render with an invalid texture, which was probably the cause of crashes and definitely the cause of rendering artifacts. Fixed by calling endRendering() / beginRendering() appropriately on the underlying TextureRenderer during resizing of the backing store of the TextRenderer. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1148 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 272: Move setColor method from TextRenderer up to TextureRenderer Kenneth Russel2007-02-202-28/+64
| | | | | | | | Moved setColor() implementation from TextRenderer to TextureRenderer and reimplemented TextRenderer's methods in terms of it. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1143 232f8b59-042b-4e1e-8c03-345bb8c30851
* Added RenderDelegate mechanism to TextRenderer to provide more control Kenneth Russel2007-02-111-19/+103
| | | | | | | | where desired over the rendered text bitmap. Added CustomText demo to demonstrate its usage. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1128 232f8b59-042b-4e1e-8c03-345bb8c30851

* Added 3D rendering methods to TextureRenderer and TextRenderer on Kenneth Russel2007-01-202-90/+230
| | | | | | | | | | | | request of several people on javagaming.org forums. Refactored existing 2D rendering support in these classes in terms of the new 3D methods. Wrote new TextCube demo illustrating how to render 2D text in 3D using the TextRenderer. Factored out FPS counter rendering into new FPSCounter utility class and updated TestTextRenderer and FlyingText demos. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1092 232f8b59-042b-4e1e-8c03-345bb8c30851
* Robustness improvements to TextRenderer and underlying RectanglePacker. Kenneth Russel2007-01-131-26/+194
| | | | | | | | | | | | | | | Added ability to specify a maximum size to which the RectanglePacker can expand. Added preExpand method to BackingStoreManager to support early eviction of unused entries instead of always expanding the backing store, and additionFailed method used when the backing store can not expand further. Added more robust free list coalescing to Level. Added support for shrinking of backing store and for eager compaction when there is a lot of vertical dead space. Added TextFlow demo which shows how to do dynamic layout of text and which acts as a stress test for the TextRenderer. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1083 232f8b59-042b-4e1e-8c03-345bb8c30851
* Added new FlyingText demo to illustrate more advanced usage of the Kenneth Russel2007-01-072-15/+34
| | | | | | | | | | | TextRenderer class; displays dynamically rotated, translated and colored text. Changed how setSmoothing() is handled by the TextureRenderer and stopped disabling smoothing in the TextRenderer. For the time being, not exposing this flag in that class to keep the API simple. Changed TextRenderer to also push/pop the texture matrix. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1073 232f8b59-042b-4e1e-8c03-345bb8c30851
* With help from Chris Campbell, fixed incredibly stupid bug on my part Kenneth Russel2007-01-062-1/+9
| | | | | | | | | | | | | | | | where the new Java 2D TextureRenderer was destroying and re-creating the OpenGL texture every frame. This was why the Java 2D Overlay class was so expensive, and why the TextRenderer wasn't as fast as it seemed it should be. Fixed bugs in all of the Java 2D demos which were covered up by this implicit sync, as well as in the TextRenderer class itself where it was missing a key sync operation. Added code to the Texture.updateSubImage() implementation to clip the incoming rectangle to the bounds of the input data and texture, to keep OpenGL from dropping almost-valid updates on the floor. Ran all of the Java 2D integration demos to verify these fixes. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1071 232f8b59-042b-4e1e-8c03-345bb8c30851
* With extensive help from Phil Race and Chris Campbell from the Java 2D Kenneth Russel2007-01-042-5/+583
| | | | | | | | | | | | | | | | | | | | | | team, added a TextRenderer class which enables high-performance rendering of bitmapped Java 2D fonts, with full Unicode support, into arbitrary OpenGL drawables using a simple API. Builds on top of the TextureRenderer class and its associated functionality; added createAlphaOnlyRenderer() and other methods to enable the TextRenderer. Caches rendering results on a string-by-string basis in an OpenGL texture using a fully automatic least-recently-used algorithm for good efficiency when rendering the same string or strings multiple times. Uses a rectangle packing algorithm, currently housed in com.sun.opengl.impl.packrect, for managing the positions of cached strings on a larger OpenGL texture to avoid OpenGL pipeline state changes. Added a TestTextRenderer demo which simply adds a moving text string and frames-per-second counter to the Gears demo; more sophisticated examples to come. (Some commented-out debugging code is being temporarily left in the new demo, to be removed in the next checkin, in order to have it in the version history.) git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1067 232f8b59-042b-4e1e-8c03-345bb8c30851
* Moved J2DTextureRenderer and J2DOverlay into their own sub-package and Kenneth Russel2007-01-042-0/+584
dropped the prefixes on the suggestion of Chris Campbell. No other changes to these classes. Added com.sun.opengl.util.j2d to the javadoc generation. Updated demos. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1066 232f8b59-042b-4e1e-8c03-345bb8c30851
