Re: [osg-users] [build] Linking Errors with OSG-3.3.0 and MSYS

Re: [osg-users] Hole in extrusion

This seems like the age-old "you can't draw a flat-shaded cube with 8 vertices" dilemma. Don't you need to repeat the same xyz vertex possibly multiple times? So that you can have a different normal at the same vertex, depending on which face you're rendering. -Paul

[osg-users] [build] Linking Errors with OSG-3.3.0 and MSYS

I can build OSG with MinGW/MSys. I get link errors when trying to compile an app against it though. Any ideas? C:\Apps\Test\win32\mingw>make Linking CXX executable ..\bin\Test.exe C:\Libs\OpenSceneGraph-3.3.0\win32\mingw\lib\libosgDB.a(Registry.obj ):Registry.cpp:(.text+0x186e): undefined referenc

[osg-users] OSG app without Console window?

On windows, my OSG apps always have a console window. I've looked everywhere but haven't figured out how to turn it off. I want the app to run and only show the viewer window. Thanks in advance ;) -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=

Re: [osg-users] BUG: osgGA::GUIEventAdapter returns wrong mouse ranges on android

I can confirm this issue. For android I use setUpViewerAsEmbeddedInWindow(0, 0, width, height) and then setMouseInputRange(0, 0, width, height). I then send the input via getEventQueue()->mouseButtonPress(x, y, button); The input coordinates from android seem to be correct at this point, althou

Re: [osg-users] OpenScenegGraph-3.2.1 release candidate 3 tagged, please test in prep for 3.2.1 release

It looks like the osg::Geometry changes (deriving from osg::Node) are not on the 3.2 branch, just on trunk. Is that correct? -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users
