Re: [osg-users] dynamic vertex array howto
Hi, it worked just fine. I guessed so, because I noticed the dirty method not on the geometry but on the vertex array autocomplete, I was asking because sometimes the documentation has only the code listing and not an actual explanation. I guess I could have tried it, but it was also to confirm that I was doing the right thing. Thank you =) Jean-Sébastien Guay wrote: Hi Paulo, What am I doing wrong? Do I need to call some method to flag that the array changed? Yep, good intuition: _geometry-dirty(); Also, since you're changing the vertices each frame, set _geometry-setUseDisplayList(false); or otherwise you'll get bad performance. Hope this helps, J-S ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Qt mouse wheel zoom howto
Hi,
I was writing an application using Qt and osg.
I would like to zoom in and out on mouse scroll.
I could not find a good way to do this, so I came up with:
void osgWidget::wheelEvent(QWheelEvent *event) {
const float delta(event-delta() / (8.0f * 15.0f));
const float x(event-x());
const float y(event-y());
const float ydy(y + delta);
const int b(osgGA::GUIEventAdapter::LEFT_MOUSE_BUTTON
| osgGA::GUIEventAdapter::MIDDLE_MOUSE_BUTTON);
_gw-getEventQueue()-mouseButtonPress(x, y, b);
_gw-getEventQueue()-mouseMotion(x, ydy);
_gw-getEventQueue()-mouseButtonRelease(x, ydy, b);
}
which actually works but it's not so elegant.
Is there a obj-zoom(0.9f); to get 10% closer or obj-zoom(1.1f); to get
10% further for example?
thank you.

[osg-users] Focus/zoom in a node.
Hi, is there a tutorial where I can see how make the camera focus a particular node, such that the node's bounding box will fit the viewer window? Thank you. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Focus/zoom in a node.
Hi, thank you for replying. Well maybe. Imagine that I load a model so big or so small that with the current camera parameters I can see a thing. I want to adapt the camera automagically so that my current loaded/selected scene/node will fit just nicely on screen. =) Paulo Robert Osfield wrote: HI Paulo, On Sun, Feb 8, 2009 at 9:23 AM, Paulo Jnkml paulo.jn...@gmail.com wrote: is there a tutorial where I can see how make the camera focus a particular node, such that the node's bounding box will fit the viewer window?
