Re: [osg-users] help me with my first osg program ...
Hi Omprakash, Clearly it's a missing include, which might be down to an error in your CmakeLists.txt file in which case having a look at CMake docs might help you on your way. Or it could be simply that Cmake isn't finding the OSG as you haven't installed it in a place it can find or that you have provided any guidance to cmake to know where you have installed/built the OSG. This goes back to knowing how to use CMake. There are plenty of docs online for CMake and would recommend you invest some time learning it as it's a great tool. Hints for further investigation are : 1) use ccmake, i.e. in the console run: ccmake . And browse there the various settings for the OSG_* entries to see if they are set correctly. 2) To diagonse the make lines invoked by the cmake sytle build run: make VERBOSE=1 These are just hints, if you struggle to get things building go have a look at the Cmake docs online.

Re: [osg-users] Help me with polytope intersector please !!!
The polytope intersector tests to see if a frustum (i.e. truncated pyramid) volume contains or intersects with geometry. In the case of a testing a polygon or a fully contained line segment, there is no single point that describes the intersection. This is fine for selection when you are primarily interested in merely determining the node the user clicked on. If you need an exact intersection point, you have to use a LineSegmentIntersector (but this makes it difficult to pick lines and points) or implement your own Intersector class that reports back more detailed intersection information. - Pete On 7/20/2012 10:00 AM, Bob Slobodan wrote: Hi guys, I'm having some difficulties with a polytope intersector.

Re: [osg-users] Help me to solve this problem
Hi This see-through/bleed-through artifact is due to the granularity of sorting used by all scene graphs including OSG, this happens because things are sorted a geometry node level and not at a per primitive level , using this method it is reasonable fast and in most cases give good results, but with certain poorer database designs or built scene-graphs where geometries overlap etc then you will see these types of artifacts Basically the way you minimize these types of artifacts is to re-structure your scene graph and or models such that they minimize overlapping bounding sphere and boxes.

Re: [osg-users] help me!
Hello
Use osgexp and 3ds Max(v8) all the time, most often with Delta3D, and
have no problems with repeating UV's.
Open your .osg file
Where it describes your 'textureUnit'{ Texture 2d{
Look for
wrap_s and wrap_t these should both be set to 'REPEAT'
osgEXP should handle this without your needing to modify your file
