Re: [osg-users] [osgPlugins] OSG 3.2.x slower than OSG 3.0.1??
Hi Robert, can you give an advice for all the cmake OSG_GL_* settings? Maybe I miss-configured something there...

Rebuild with Release is much better! :D For the statistics: OSG 3.2.1-rc1 / Win7 64bit / mingw QtCreator / cmake_build_type Release Thank you!

[osg-users] [osgPlugins] OSG 3.2.x slower than OSG 3.0.1??
Hi all, I successfully build 3.2.1-rc1 on Win7 with MinGW+QtCreator, but all framerates are lower than my good old OSG 3.0.1. I made some side by side tests with different 3D-models and osgviewer-3.0.1 vs. osgviewer-3.2.1-rc and the times for draw and GPU are at least doubled!! Are there any new cmake options I should check? Thanks for any help!!

Re: [osg-users] [osgPlugins] OSG 3.2.x slower than OSG 3.0.1??
Hi Robert, I tested some airport models, all OpenFlight with jpeg, png and dds textures. All statistics (vertices, drawables, etc.) are the same, but interestingly event, update and cull are also increased, which maybe points to a not only OpenGL related problem? Thanks!!

Re: [osg-users] [osgPlugins] OSG 3.2.x slower than OSG 3.0.1??
Hi all, I will keep testing, but I think I found my mistake: I always used cmake_build_type with MinSizeRel or left this option empty. Setting cmake_build_type = Release gives OSG a boost...

Sorry, it is me again... :( The cube now works perfectly, but all other OpenFlight and *.ive files are still slower under 3.2.1. And my own application loses one third of its framerate...

[osg-users] [osgPlugins] osgText with disabled GL_DEPTH_TEST
Hi all, I have some kind of quality problem with the textured glyphs from osgText. For a display I would like to have text on every node in the scene, with the text staying on top. So I disabled the depth test for all text geodes. Looks good. But when I start to change the text with setText() every second, the textured glyphs get somewhat dirty... (See attached picture with GL_DEPTH_TEST off/on) Thanks for any help!

Re: [osg-users] [osgPlugins] osgText with disabled GL_DEPTH_TEST
Hi Robert, here is my code so far: _font = osgText::readFontFile( fonts/arial.ttf ); _text = new osgText::Text; _text-setFont( _font ); _text-setAxisAlignment( osgText::Text::XZ_PLANE ); _textGeode = new osg::Geode; _textGeode-addDrawable( _text ); _textGeode-getOrCreateStateSet()-setMode( GL_DEPTH_TEST, osg::StateAttribute::OFF ); addChild( _textGeode ); _text-setDataVariance( osg::Object::DYNAMIC ); I think I tried everything I found about this topic: different bins, different GlyphImageMargins, etc.. It looks like a problem with the alpha values in combination with small text. Text three times the size does not show this dirt...

Re: [osg-users] [osgPlugins] osgText with disabled GL_DEPTH_TEST
Hi Robert, I found a dirty hack... I use the good looking version with GL_DEPTH_TEST enabled, but apply a vertex shader for all text nodes with gl_Position.z = 0.0 =D Tim. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=54613#54613 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] [osgPlugins] osgText with disabled GL_DEPTH_TEST
Hi Robert, you are right. I do not like this solution either. I think I have to look deeper inside the osgText::Text.cpp, because the dirty textures only happen, if you change the text. I have two text nodes added to an object, one changes its text, the other does not. The first one gets more dirty over time, the second stays clean. :( If I change the fragment shader to Code: gl_FragColor.rgb *= TextureColor.a; I get perfect letters in black boxes. Are the glyph textures mipmaped? Maybe it is an alpha-mipmap problem? Thanks!

[osg-users] [osgPlugins] DDS Texture vanish with LINEAR_MIPMAP_LINEAR
