Robert, Thank you for the wonderful job that you have been doing on OSG. I have been using it for over 10 years.
I am trying to update my application from 3.0.1 to 3.2.1 and discovered that osg::geometry class has deprecated the indices capabilities. I think that functionally that has been around for years should not be quickly eliminated like this. This is going to cost me a lot of time redesigning everything. My application deals with large amounts of lidar data. (22 million points per scan, 20-50 scans per scene; that's a 1B points). In order to do this I have to cache and swap data a lot. I am using your IVE file to quickly move data in and out of memory. By removing the indices from osg::geometry, the OSG and IVE files will explode to 4 X the size and take 4 X longer to swap in and out. I only store the points once and use the indices to create the polygonal geometries when I need then. Not everything is always being displayed. I rely on osg::geometry as a data storage object in memory everywhere. I know that I can use the deprecated_osg::Geomerty in the short term but please consider creating a new osg::IndicesGeometry class to preserve functionality of Indices in the OSG and IVE files and don't explode the data until it is needed by OpenGL. I think the explosion of the data into OpenGL is best served inside the IndicesGeometry class allowing applications to manage the data in Indices form.
