[Opensg-users] OSGNavigator (bug?)

[Victor Haefner]

Hi all,

I needed screenshots of my scene from the front, side, and top. It works,
need no help, just found something perhaps :

//grab some filegrabforeground

            Vec3f from = navi->getFrom();
            Vec3f up = navi->getUp();

            beginEditCP(grab);
                grab->setActive(true);
            endEditCP(grab);


            navi->setFrom(Vec3f(0,1.25,7));
            navi->setUp(Vec3f(0,1,0));
            mgr->redraw();

            navi->setFrom(Vec3f(7,1.25,0));
            navi->setUp(Vec3f(0,1,0));
            mgr->redraw();

            navi->setUp(Vec3f(1,1,1));
            navi->setFrom(Vec3f(0,8.25,0));
            navi->setUp(Vec3f(0,0,1));
            mgr->redraw();


            beginEditCP(grab);
                grab->setActive(false);
            endEditCP(grab);

            navi->setUp(Vec3f(1,1,1));
            navi->setFrom(from);
            navi->setUp(up);

whithout the lines navi->setUp(Vec3f(1,1,1)); inbetween it could happen that
the navigator would not jump to the new location (happend for the last 2
setFrom())

just thought I should tell someone.. I don't know if I did something
terribly wrong or not.. hope its usefull to someone..

I suspect there is some vector calculation in the background whitch doesnt
work when up x from = (0,0,0)
