[osg-users] intersections

Hello, I use osg:: LineSegment to perform an intersection between a ray starting from a wand and the objects in my scene. Here is my code: osg::Vec3 wandpt1; osg::Vec3 wandpt2; line = new osg::LineSegment(wandpt1,wandpt2); osg::BoundingBox modelbox; modelbox.expandBy(modelTransf-getBound());

Re: [osg-users] StateSet and changes

Hello Yes, great job ! There was an other problem : I did an optimize() of my model ; at that moment, all stateSet lost their geode parent... and all of them were suddenly linked to the same and main parent (the cabine of the aircraft). Now is much better ! Thanks again. --

Re: [osg-users] osgVolume volume rendering ?

Hi Manu, You data DICOM data rendering suggests that the air around the subject is returning a high intensity value rather than a low one. This is not something I've seen with the DICOM datasets I've tested, so try other data. A transfer function would certainly be one way to pick out the data

Re: [osg-users] osgVolume volume rendering ?

Hi, Hehe, now that you have succeeded at getting something, you start to get into the problematics of volume rendering. Namely, to get a nice visual representation, you have to provide a suitable transfer function. The example uses some hard-coded transfer function (osgVolume supports only 1D

Re: [osg-users] Event Handling from outside a Viewer

Hi Tom, Another solution would be to subclass from osgViewer::Viewer and add your own removeEventHandler method, then once you move to 3.0 you'll just be able to drop your own Viewer class or just remove the method, and optional compile would even let you build against 2.9.x/3.0 and 2.8.x without

HI Keith, The easiest way to do what you want is place your six RTT Camera's as nodes in the scene graph and have a callback in on them that switches them off either via a NodeMask or via an osg::Switch node so that they only render for one frame, or one nominated frame, or whatever metric you
