Re: [osg-users] Removing the tgz, osgtgz and zip plugins
Hi all, We already have a ReaderWriter using zlib, reading from stream and from file, writing to file. But we compile it with our Makefile system, not with CMake.

Re: [osg-users] Removing the tgz, osgtgz and zip plugins
Hi Robert, Unfortunately our plugin read only .gz file, not .zip nor .tar.gz. I didn't know about osg 2.7 .gz plugin, we always use osg 1.2. We hope to upgrade to 2.X in the next months, and I will closer look at CMake in the same time. Regards, Johan.

Why change something that is not broken, might not be the best solution but they work Completely seconded. Maybe they should be reimplemented using a better method, but to throw out support for zip files would be a mistake - it is infinitely easier to move models around in a zip file than to explain to a designer how to make an osga file or ive file, requiring extra tools and so on. It is also easier to archive such models - everything is in one place and I can always open them. IVE or osga formats can change over time and I cannot load them back into a modeling tool. I think these should be kept and perhaps fixed.

[osg-users] Removing the tgz, osgtgz and zip plugins
Hi All, The tgz, osgtgz and zip plugins have been part of the OSG from the very early days, but they are really hacky using a system(..) call to unpack the archive file into a temporary directory, then call readNodeFile on the files enclosed, then remove the temporary directory. In the early days this was kinda useful for quick a dirty wrapping up of models that contain .osg and .rgb files but these days we have the .osga archive format and the .ive binary format that support these requirements in far more slick and reusable way - without the hacky system calls or temporary files. So... my proposal is to remove them from svn/trunk and place them in the deprecated annex of the svn repository. Thoughts?
