Re: [osg-users] Problem with osg::Fog

Hi, Strange... My small fog test program works fine on my laptop at home ?!?! All test cases behave as expected. Same OSG version (2.2), different hardware and linux distribution. I still get (at home) the same warning though: --- detected OpenGL error 'invalid enumerant' after

Re: [osg-users] LineSegmentIntersector - nodePath invalid?

2007-11-14 Thread Robert Osfield
Hi Glenn, Your analysis is correct, when the DatabaseCacheReadCallback is deployed one can potentially end up with dangling pointers. Switching to ref counted NodePath would be the safest way to fix this. There is a performance penalty though, which is why a straight NodePath was used. There

Re: [osg-users] About the plugins...

Hi Manu, Extending the .osg format with your own callbacks/nodes/state/drawables is pretty easy - just look to see how all the NodeKits do it i.e. they have src/osgPlugins/osgParticle, src/osgPlugins/osgText. The .ive format isn't extensible in the same way though, to extend it you have to go in

Re: [osg-users] How to get the texture from a osg::camera with a GL postdrawcallback

Hi, You are probably best adding OpenGL calls as part of the scene graph, by subclassing from osg::Drawable as per the osgteatpot example. Then just add this custom Drawable to the subgraph below your RTT Camera. Robert. On Nov 14, 2007 1:55 AM, 易成 [EMAIL PROTECTED] wrote: Hi Everyone, I

[osg-users] Problem with OSGWiki Intersection example at function accept(intersectVisitor) by using OSG v2.0

Hello OSG mailinglist users, I have a problem with the osg::IntersectVisitor at osg V2.0. I will use the IntersectVisitor to detect a hit between a 3Dmodel and a ray (LineSegment), so I build a testprogram based on the http://www.openscenegraph.org/projects/osg/wiki/Support/Tutorials/Inters

I'm taking a first look at lightpoints. If I needed a single lightpoint with half the light sphere green in one direction and the other half red in the opposite direction, can this be readily done? With a single lightpoint, or two half lightpoints? Is this what lightpoint Sector could be used

Hi Umit, As far as I know, TerraVista is the only software that can generate TerraPage format datasets: http://www.presagis.com/products/terrex/details/terra_vista/ But it is probably out of your price range. Is there a particular reason you need TerraPage format? If not, I suggest you look into

Nvidia has something called CUDA, which is essentially a C-like programming language that compiles to the GPU. I haven't looked into it, but my guess is, that's a tool real-time raytracing could benefit from, if it hasn't already. I think if we've learned anything over the past 10 years or
