Re: [osg-users] problem of rendering overlaped models.

2013-02-16 Thread Preet
When you say weird what do you mean? If you have polygons that are
positioned/aligned very closely to one another you might be seeing
z-fighting (http://www.zeuscmd.com/tutorials/opengl/15-PolygonOffset.php).
In that case you can tell OpenSceneGraph to use polygon offset on one of
the models.

osg::ref_ptrosg::PolygonOffset polyOffset = new osg::PolygonOffset;
polyOffset-setFactor(1.0f);
polyOffset-setUnits(1.0f);
ss = someNode-getOrCreateStateSet();
ss-setAttributeAndModes(polyOffset);

 hi friends:


  i have 2 models to  render, some part of which are overlaped .  so the
 result is some kind of weird.  how can i resolve this probem?

 do i need to split the model and align them?  or set different render
 details for the 2 models?

Are the models transparent at all, or opaque?

Re: [osg-users] Low frame rate for one animated character.

2013-02-16 Thread Peterakos
Edit  for the last question:
If i face such difficulties with only 1 character, how do the modern
3D action games work ?
