Thanks, Robert -- I agree it might be useful to enhance the ReaderWriter interface at some point in the future to support this application. For now, I'm going to go ahead and submit what I have. We will encounter some issues with plugins returning error codes, which, hopefully, the community will chip in and help resolve, and we'll also encounter problems with the 3rdparty dependencies spewing error messages into our output stream. Not sure what we can do about that. Here's some brief usage notes regarding the submission: I'm submitting this as a new application (rather than example) and calling it "osgio". Simple usage is as follows: osgio osgio -csv osgio flt obj 3ds bmp In the first form, osgio builds a list of potentially supported extensions, tests OSG for support, and outputs the extension and ReaderWriter class name if OSG supports that extension. In the second form, osgio outputs in CSV format. Each line represents the support status of a given extension. Columns contain the extension name, ReaderWriter class name, and support for read/write of Nodes, Images, Objects, and HeightFields represented by an "X" (absence of "X" indicates a lack of support). The third form tests a specific set of given extensions. The second and third forms may be combined to output a set of specific extensions in CSV format. Will post to osg-submissions shortly...
