* 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

* 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

Current state of code is documented in src/classes/com/sun/opengl/impl/nurbs/README.txt. Example applications require Java 1.5 and are not currently built by default.

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

* Fixed Issue 296: TextureIO cube map support brokenKenneth Russel2007-04-212-36/+56
| | | | | | | | | | | | | Fixed code paths supporting cube maps. As a positive side-effect, the VertexProgRefract demo's cube map is now rendered completely correctly; inversion of the positive and negative Y images, and the negative Y scale factor on the texture matrix, are no longer needed, and the seams around the top image are gone. Fixed code relating to automatic mipmap generation in the presence of only GL_ARB_texture_rectangle and not GL_ARB_texture_non_power_of_two. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1212 232f8b59-042b-4e1e-8c03-345bb8c30851
* Re-fixed Issue 226: JOGL seg faulting on Solaris AMD64Kenneth Russel2007-04-211-17/+1
| | | | | | | | | | | The autogenerated GLX_JNI.c was not receiving a prototype for glXGetProcAddressARB and so was receiving the implicit one returning an int, which is obviously wrong on 64-bit architectures. Re-fixed this bug by providing a prototype; removed the workaround in X11GLDrawableFactory. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1211 232f8b59-042b-4e1e-8c03-345bb8c30851
* Fixed Issue 226: JOGL seg faulting on Solaris AMD64Kenneth Russel2007-04-201-6/+6
| | | | | | | | | | | | The implementation of glXGetProcAddressARB on Solaris/AMD64 had a similar problem to that seen on Linux/AMD64 distributions: internally the return value is being cast to a 32-bit value and then sign-extended back to 64 bits, causing the high half of its function pointer return values to be lost. Worked around by using dlsym() for lookup on this OS as well as on Linux/AMD64. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@1210 232f8b59-042b-4e1e-8c03-345bb8c30851
