Hello all. Before I start hacking on osgWidget again full force (in preparation for OSG-2.9 or OSG-3.0) I wanted to continue peddling my wares here and generating interest in a different (BUT RELATED) project of mine called osgPango.Basically, I'm writing osgPango to achieve the following (in order): 1. TOP quality 2D fonts in OSG on all supported platforms. 2. A sophisticated layout/markup system for complicated text. 3. An extensible rendering backend that lets users create callbacks for the actual "rendering" of the font character. 4. Speed, speed, and more speed. 5. Clean and intuitive API that exposes all elements of a body of text (the position of each character, etc.) Goals 1, 2, and 3 are accomplished; 4 and 5 are debatable. Lets get started with some obligatory screenshots: http://cubicool.plopbyte.net/osgPango-normal.png Here is some undecorated text (no shadows or outlines) showing one of Robert's posts from earlier this week. Notice how the text is justified to a certain width, and that it is no problem for osgPango to change font style or color midway through a sentence or word! Also notice the font quality, where no character is missing a pixel on any side and straight vertical lines are sharp and not "smudged" along two pixels. http://cubicool.plopbyte.net/osgPango-shadow.png Same as the above screenshot, except that the paragraph width is shortened and there are now +1, +1 drop shadows (their offset is configurable). http://cubicool.plopbyte.net/osgPango-outline.png Here we change our alignment to RIGHT and add 1px black outlines to the fonts. I'd like to get other people who need high-quality 2D fonts to start keeping an eye on osgPango so I can start seeing how folks want to use and extend it's feature set (where possible). I've tested it personally on Linux and Vista 64, but I'd need someone else to try it on Mac. (As an aside, it should use the ATSUI backend on Mac, giving some pretty nice font quality! It uses FreeType on Linux and ClearType on Windows; to get it compile on Windows I simply used the binaries from the GTK project) The main osgPango website is here: http://osgpango.googlecode.com It won't be long before I consider it done (for me) and move back to osgWidget and start helping more with osgAnimation, so let me know soon if you're interested and need it to do something it doesn't. :) With time I hope to be able to get osgPango in the core and replace osgText, but we'll have to see. :) The advanced layout powers and pluggable rendering backends are two things it would be VERY hard to add to osgText. As far as speed is concerned, osgPango is currently just as fast as osgText for most normal usage, though obviously every time you change font families or color or size you introduce a state change. :) Placeholder code is also in place for someone to add a GLSL shader to do the multitexturing instead of the complicated osg::TexEnvCombine() object I currently use, and I'm sure we'd see some significant speed increases there as well (when effects are used or desired). _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
