OK, looks like the fix could be Code: IF(APPLE AND NOT (OSG_WINDOWING_SYSTEM STREQUAL "Cocoa")) RETURN() ENDIF() This applies to avfoundation (which only compiles on OSX anyway), as well as osgmultitouch and osgoscdevice examples, which will continue to compile on non-apple platforms

Re: [osg-users] Realtime Pointpicking

Hi Daniel, The PolytopeIntersector is the simplest route. If you want to make things more efficient then you may well need to come up with a custom approach. The LineSegmentIntersector is able to take advantage of KdTree graphs if they have been built for your scene graph and enables O(logn)

Re: [osg-users] Best way to cull object hidden by a mountain

Have you considered looking at osgEarth? There's a lot of capability there, including line rendering to textures with CSS-like styles using AGG. I've used it for this sort of thing, and when you're already DOING geospatial stuff, you should really think about using the OSG toolkit that was really

Hi Robert, Thanks for your clarification about OccluderNode. I already looked at the osgocclusionquery example. If I'm right, it just need to add an OcclusionQueryNode to contain the node wich have to be occluded by the rest of the scene graph. I wasn't able to make it works so I may need to

[osg-users] Realtime Pointpicking

Hi, I have a Pickhandler and a dynamically changing scene which consists only of a geometry node. To be more specific, the geometry node represents a point cloud consisting over ~10 vertices. Using a line intersector makes it nearly impossible to get an intersection, but the Intersector I

Re: [osg-users] Best way to cull object hidden by a mountain

HI Valerian, The osg::OccluderNode is not appropriate for what you are trying to achieve, it only works when you have convex planar occluder geometries that you can use to do the culling. It's useful for town or building scenes where walls can form large occluders relative to screen space. A

Re: [osg-users] Best way to cull object hidden by a mountain

I might show some pieces but there is a lot of code and i'm not allowed to share it :( Right now I need to understand how occlusion culling is supposed to be used with HeightField (is it is possible). I made a few tests in my code but I did not keep them as nothing was working.

Re: [osg-users] Pass an osg::Texture2D to CUDA driver api

Hi Robert, thanks for the input! When thinking about this, I really want to find another approach than the "main loop" because I need to execute the CUDA code at a very specific point in time. (After a RTT Camera Texture has been written, but prior to rendering another texture). Therefore, I

Re: [osg-users] Using InfinitePlane

Hi, InfinitePlane is an osg class, defined in osg/Shape. According to osg documentation, InfinitePlane cannot be rendered but is used to support collision detection, so I guess I can use it to compute intersection between mouse clic and an imaginary ground. I'm working on a GIS app, rendering
