Petr, OSG is very different from vega (I switched to osg from vega years ago). Your general experience using vega will be helpful, but the details of how to implement specific functionality will not be very helpful. There are a number of tutorials available, and the examples are invaluable.
For your intersection question, you'll need to use osg's osgUtil::IntersectionVisitor (look at the osgintersection example). Brian This is a PRIVATE message.

Hi All, I'm a new osg user and these days I'm trying to use it. Now i have tried some tutorials and read some docs, and i have one questions. because we have used for visualization Vega (by Multigen, now Presagis), ve can add to scene some Isectors whitch checked collisions with another objects, or hold the cars on the road. Can i do this in OSG (i didn't found Isectors theme on this website), and how to do it? Here is the part how to create Isector (create, position, masks, callback) in Vega: #define VGIS_TERR1 0x00000001 //terrain face, for callback #define VGIS_SOBJ1 0x00000100 //static face, for callback vgIsector *isector; vgPosition *pos; //(x,y,z,h,p,r) pos=vgNewPos(); vgPosVec(pos, 0.0f,0.0f,0.0f,0.0f,0.0f,0.0f); //isect example isector=vgNewIsect(); //new Isect vgPos(isector, pos); //pos vgIsectTarget(isector, vgGetScene(0)); //target detect (scene) vgIsectClass(isector, VGIS_TERR8); //mask vgAddPlyrIsect(mv_player, isector); //isetc to player vgAddFunc(isector, VGIS_HIT, <callback>, <param>); //callback vgUpdate(isector); //update vgDelPos(pos); //del tmp pos And some screenshot from runtime loop, the green line is detecting, red no. Z-isectors hold the cars on the road. 3rd image - left isector is greeen because ho has crashed with white cube (static object).
