A new TextureObjectManager class + also caches a list of expired texture objects for reuse, and allows new newly loading + imagery to reuse expired texture objects, with the imagery automatically subloaded + to the reused texture objects. This reuse happens transparently and benifits other + OSG usages such as the OSG's Terrapage loader. + + The new .ive binary plugin was developed by Uni-C's VR-Center, and kindly + submitted as open source, adds support for binary reading and writing OSG nodes + drawable and state (including compressed/mipmapped) textures. The .ive + format produces a much faster load time and smaller file size then .osg + New osgGL2 library Adoption of OpenThreads for cross platform threading support.
