Re: [osg-users] Questions about physic engines.
Thanks. Just one question, OSG renders at the maximun amount of FPS it can, but ODE requires a fixed time step. How do you solve this problem? Thanks a lot. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=23813#23813 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Questions about physic engines.
Hi mates. I have several questions regarding about physics engines in OSG. BTW, I'm a OSG beginner. If I want to use ODE, must I add osgPhysics plugin to my OSG? How can I load a scene with physics values? Let's say I'm creating a scene in 3Ds MAX, and I export it to COLLADA (or any other format). Does OSG or osgPhysics read these values (mass, friction...)? And the most important, how can I tell 3Ds MAX that objets have different physic properties? And the last one. Usually physics engines requere a fixed (or almost) time step, ODE is one of them. How should I manage that inside OSG, I mean, after integrating ODE with ODE? Thank you very much for your time and help.

[osg-users] Does anyone remember how is a mirror/reflection matrix?
Hi friends! Does anyone remember how is a mirror/reflection matrix? just to simulate a very clean floor (repeating models above). I'd like to create a osg::MatrixTransform and using osg::Matrix, pass this mirror matrix. Thanks. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=20935#20935 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] How can I get last frame time inn order to create indepent FPS aniamtions?
Good idea, as expected, it works perfectly. But I'm curious, do you know why old my approach does not work? (calculate frame time, is it because of threads?)

[osg-users] How can I create a osgViewer windowed?
Hi all! osgViewer starts always in full screen mode. How can I tell it I would like a window or windowed app? Thanks a lot. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=20302#20302 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] How can I create a osgViewer windowed?
Wonderful! Thanks a lot. BTW, is there any way to automatically center that window? or get screen size and window size? Just to let my window nicer. (from OSG, not from Win32 API) Thanks Tueller. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=20305#20305 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] How can I get last frame time inn order to create indepent FPS aniamtions?
Hi all.
How can I get last frame time inn order to create indepent FPS aniamtions?
For instance, something like m_last_time_frame:
Code:
double angle=0;
while (!viewer.done()) {
angle=angle+0.1*m_last_time_frame;
viewer.getCamera()-setViewMatrixAsLookAt(osg::Vec3(0,-400,150),
osg::Vec3(0,0,0), osg::Vec3(0,0,1));
viewer.getCamera()-setViewMatrix(osg::Matrix::rotate(angle*DEG_TO_RAD,0,0,1)*viewer.getCamera()-getViewMatrix());
viewer.frame();
}
Thanks.
