[osg-users] clip distance

Hi all -- Does anyone know of an OpenGL extension to GL 2.x that adds the clip distance feature found in GL 3 / GLSL 1.30? It does not appear to be in ARB_gpu_shader4... Thanks. -- Paul Martz Skew Matrix Software LLC _http://www.skew-matrix.com_ http://www.skew-matrix.com/ +1 303 859 9466

Re: [osg-users] clip distance

Thanks for digging and verifying my suspicion. Too bad; many features in GL3 are available as extensions in GL2, which really eases the porting effort. However, looks like clipping is just one of those cases where the code has to change between versions. Paul Martz Skew Matrix Software LLC

, then later changing the code and assuming it was ref counted, and therefore introducing a leak. Yes, it's best to always use ref_ptr. Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com +1 303 859 9466 -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg

Re: [osg-users] smooth angle on normal calculation

There is the osgUtil SmoothingVisitor, which will compute a normal per vertex by averaging the facet normals of shared polygons. Will that do what you want? Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com +1 303 859 9466 -Original Message- From: osg-users-boun

Re: [osg-users] Inserting a Switch node into the SG

How are you determining that you are getting the wrong results? What you show as the result seems impossible for the code you've posted, as 'parent' only adds one child: the switch. I saved the scenegraph to a file and looked at it. When are you doing the file write? I'm concerned

Re: [osg-users] osg::ref_ptr used anymore

I think you'd benefit from looking at some OSG examples (all of which use ref_ptr) and reading the memory management section in the OSG Quick Start Guide (http://stores.lulu.com/pmartz). Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com +1 303 859 9466

Re: [osg-users] Drawing a line once( bullet physics integration )

performance bottleneck is the draw time for lots of lines and points, encountered in very complex scenes. Most consumer-grade graphics cards fall flat on their faces when rendering points and lines. Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com +1 303 859 9466 -Original Message

Re: [osg-users] Ground clamping to paging terrain

There is an osgSim::ElevationSlice that might be useful here, because it is smart about paged databases and will go to the highest LOD to get the elevation values. Paul Martz Skew Matrix Software LLC http://www.skew-matrix.com +1 303 859 9466 ___ osg

Re: [osg-users] Can I change the plugin directory structure?

Incidentally, this has been discussed a lot in the past, so searching the archives would have turned up all this info You don't have to be on this list very long to see the same question pop up multiple times. I'm guilty of it myself. :-) -Paul
