Hello everyone, I've just been trying out OSG, and I have some questions I've not been able to answer by reading the docs.
I've got one object (loaded from a .3ds file), and I want to position an object on it, to move on the surface (call it the bot). The way I thought of doing it is to use a LineIntersector to the Z-direction of the bot, and whenever it moves forward, find the point right underneath it, and snap it there. What I want to find out is how to position the bot on the object in the first place. When I made a similar mover in VTK, I found the closest point on the surface to the world origin, and positioned my bot there. Assuming the normals are unified (either all inside or outside), I can position the guy on the outer surface after this. I've not been able to find a similar function anywhere in OSG. Second, I'd like to have a way of recording a particular path that the bot has followed over the surface, for replay later. I would also like to be able to load this path from a file, or specify a point on the surface (possibly in a radial coordinate system) and position the bot directly on it. Does anyone know of a way to do these things? Thanks, Shash _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
