Re: [osg-users] Unspecified osgShadow problem
Hi Ümit, When I used "osgshadow --noUpdate --sm" resulted screen look like osgShadowError5.jpg [...] My System : XP SP2, ATI Radeon HD 2300, OSG 2.9.5 last Repository Look at the shadow in your osgShadowError5.jpg, you'll see that the cone's shadow is under the cube and vice versa. It has been discussed before on this list that on some ATI drivers, some texture coordinates are inverted (I don't remember if you need to negate the t coordinate or something like that) when doing shadow texture lookups (sampler2DShadow). Search the archives for details. Unfortunately I don't think the problem has been characterized precisely enough (some drivers have the problem, some don't) so no one has made a check for it in the osgShadow code yet. As for Shadow Texture the problem might be the same or it might not be. I'm not sure, I don't even think it's used that much. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] [osgPlugins] GoogleMode
I think a possible solution to this is osgconv -o googlemode [model 1.flt] [model 2 .dae]. Is this valid? I think this might be the solution. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=14625#14625 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

The Z-up is popular in the vis-sim industry as it feels more natural to assume X-east, Y-north, Z-up. But it's not hard-coded or anything, just the default. You can change it without problems by specifying an up vector of osg::Vec3(0,1,0).

Yes .osg format supports callbacks, but you do need to provide the implementation of the reading/writing of the callback. Have a look at src/osgPlugins/osg/AnimationPath.cpp for example code.

Re: [osg-users] race condition in GraphicsWindowWin32?
Hi Cory,
How did you close the application? Pressing escape or closing it via
the window close button?
Does the problem happen with other examples, such as osgwindow?
