Hey folks! Wanted to solicit some advice, if that's cool. :) If you take a look at the osgPango site and browse to the bottom, there is a video demonstrating usage with osgPango (a font/text library I'm working on before diving back into osgWidget) and AnimTK (an animation library by Cedric Pinson).
A link to the video is here: http://the-bob.org/~jlmoles/osgPango/osgPango-animtk.wmv At any rate, my question is this: in that video, we're using AnimTK to adjust the positions of the quads to simulate the pulses they make. However, as you can see, there are strange black artifacts around the glyphs when viewed from the front, and I was wondering if anyone had any advice as to what is causing this or if it's even avoidable at all. Some key things: - This is a single osg::Geometry object; I'm pretty sure I could make each glyph a separate object and achieve the desired effect. However, it would be entirely too slow. - The quads themselves are multi-textured GL_ALPHA images using a complex osg::TexEnv object. I disabled this, but it didn't seem to make any difference. - For this particular test, I made sure each quad had a descending Z value. I feel pretty sure this has something to do with the draw order of the Geometry, but I'm not entirely sure that it is something I can avoid given my constraints and usage. Has anyone seen something like this before? Any tips or advice? _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
