Thanks Alberto. The answer helped me to resize the model as required.

Hi Zev, you can get the total dimensions with the osg::BoundingBox of the object. Later you can scale it to the right size placing it under a osg::MatrixTransform node with a scale matrix. -- Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Scale model node to specific size
Hi, I wonder if there is a way of scaling a model to a specific size? So if i have two models that have different sizes when loaded into osg, i want to scale these two models so that they have the same lenght or width. Example if i have two models of cars they should both have X length in my osg application regardless of how big they were when created in some model program. I know i could just create the models in the right size to start with. but this is a problem when adding models made by other people. Thank you!
