Re: [osg-users] Testing of SVN version please

OpenSceneGraph compiles cleanly in the RelWithDebInfo configuration. osgviewer cessnafire.osg There is an issue with toggling textures ( it becomes unresponsive or erratic after a while ) which is fixed by using --SingleThreaded Ubuntu 7.10 Linux 2.6.23.14 #2 SMP Wed Jan 30 16:54:58 GMT 2008

Re: [osg-users] Testing of SVN version please

Hi Robert, I think you forgot to commit osgGA/StateSetManipulator because it's complaining about the clone() not being declared. However, when I add the declaration it compiles and the texture toggle works as expected. Cheers, -Tony ___ osg-users

Re: [osg-users] node names not preserved going from flt to ive/osg

We have had the same problem, but found that inserting a comment into the OpenFlight nodes you wish to preserve does the trick. A comment becomes the description of the node and the RemoveRedundantNodesVisitor checks for an empty description before allowing a removal. Cheers, -Tony

Re: [osg-users] Depth buffer

Re: [osg-users] How to correctly fill Drawable (PrepareDisplayList)

Hi Lukas, At a guess, the error code you are getting is generated by glNewList() because prDisplayList has not been initialised by calling glGenLists() first. Try setting a breakpoint on the glNewList() line and look at the value of prDisplayList. OpenGL requires a non-zero display list name.

Re: [osg-users] How to make sure that both the back and the front side of a polygon are lit...

Hi Sunil, Just to be clear, you also need to specify a two-sided light model to make OpenGL apply both front and back materials. The osg::LightModel class allows this. Cheers, -Tony ___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] How to map an image to a long width object

Hi Zhanglicheng, osg::Texture2D is derived from osg::Texture and that class has a method called setWrap(). This allows you to set how the texture repeats over a polygon in each dimension. Have a look in the header file or the reference documentation for the details. Cheers, Tony

Re: [osg-users] Custom Vertex Attributes Binding

Hi Jeremy, The glsl attachments have been squashed - could you attach them as .txt, please? I believe you have to bind shader vertex attributes as PER_VERTEX as opposed to colours and normals which can be PER_PRIMITIVE. Then copy the line that calls push_back() on gridCoordinates so you have 4

Re: [osg-users] Custom Vertex Attributes Binding

Hi Jeremy, It turns out that in the version I was using, osg-2.8.3 there are checks in osg::Geometry::drawImplementation() that would prevent the geometry being drawn when the traditional vertex position data is not present and generic attribute zero is not present. This is not the case for
