Re: [osg-users] Geometry Merging Problem
Hi if you are using osgconv at any stage to convert your model, it implicitly invokes optimizer. you can control this with env var OSG_OPTIMIZER, to turn optimizer off you can pass OSG_OPTIMIZER=OFF Cheers. 19.02.2013, 20:38, "Adam Stambler" ada...@gmail.com:Hi All,I believe I am having trouble with OSG automatically optimizing my sets of Geometry.I am visualizing a 3D reconstruction using OSG. Each part of the reconstruction is put into its own OSG Geometry and Geode. All of the parts are then put a group and saved to an .ive file. In another application, I load the ive and try and select each reconstructed Geode node. When I click on one part , parts are selected. It looks like Geometry in a few nodes have been automatically merged. My question is: is there any automatic optimization somewhere? Perhaps things are optimized when they are made IVE file? Either I implemented something incorrectly (very possible) or something modifies my scene graph. I am not explicitly calling osgUtil::Optimizer.

Re: [osg-users] Geometry Merging Problem
Hi Folks, Sorry for the spam. It turns out my problem was due to how I was coloring my selected geometry. For some reason changing the primitive color is changing the colors of multiple geodes.

Re: [osg-users] Geometry merging problem
A single Geometry can only have one StateSet and can't change OpenGL state
within a Geometry, so I'm not sure how you expected this to work. Other than
building a texture atlas, your best bet would be to leave them as two
separate Geometries.

Hi all,
I am trying to merge two geometry objects that have two
different textures by using the merging function:
bool Optimizer::MergeGeometryVisitor::mergeGeometry(osg::Geometry
lhs,osg::Geometry rhs)
After calling this function, one of these objects looses its
own texture. In fact it inherits the texture of the other
object. did anyone already try this function or know how to
merge two geometry objects correctly ?
thanks.
The following snippet code shows how I did the merging:
osg::ref_ptrosg::Geometry mergeGeoms(osg::Geometry
*g1,osg::Geometry *g2) {
osgUtil::Optimizer::MergeGeometryVisitor::mergeGeometry(*g1,*g2);
return g1;
}
