[osg-users] BlueMarble example

I was using some code from the osgbluemarble.cpp example. I am getting an error stating that ImageOptions is not a member of osgDB. I have been looking in the documentation on the website and have not found anything. Can someone tell me what has replaced this or where it is now? Thanks. _

[osg-users] Volume Rendering Software (again)

Hi all, I've got a few moments downtime, so I thought that I would attempt to convert the previous volume rendering software that I posted to a later version of OSG. Well, I've just realised that I posted an older version of the software last time :-[ !! It has been a long time! So hopefull

Re: [osg-users] RTT, ParticleSystem, Depth

Robert, My RTT camera has a postdraw callback. When I call glDepthMask( GL_TRUE ) in the RTT camera's postdraw callback, the flickering stops. The whole reason this happens is that osg::StateAttributes only have an apply() method. They must not restore() the previous state. Don't you think the

[osg-users] RTT, ParticleSystem, Depth

Robert, I have an RTT setup, with particle systems. When I put the particle system behind a geometry which is transparent, the particles are not drawn behind the geometry. The geometry in question has setRenderingHint( TRANSPARENT_BIN ) set. The particle system draw() function sets glDepthMask(

Re: [osg-users] osg::Uniform logic error?

Hi Paul, Hmm, if both are not valid the expression tested would be (false != false), which evaluates to false. The method does not return in that case. It only returns if one of the arrays has been allocated and the other one hasn't. OK, so the error is the opposite of what I thought it was

Paul, There are several messages on the board that imply that INHERIT_RENDERBIN_DETAILS, when specified with a bin number, influences the CullVisitor to create a "nested" render order. I was under the impression that, if an application has a top-level rendering order over objects that it was poss

Hi J-S, As Chris mentioned, PROJ4 is the definitive toolkit for coordinate conversions. In addition: OGR (http://www.gdal.org/ogr) has an easier-to-use wrapper around PROJ4's capabilities (http://www.gdal.org/ogr/classOGRSpatialReference.html) which is handy because it can read OSG WKT projection
