A fork of OpenSceneGraph focused on speed, and less focused on accuracy & backwards compatibility.

This fork was created to experiment with performance enhancements for OpenMW, that are too controversial to be included in the general purpose OSG project - either for design reasons or backward compatibility reasons.

OpenMW still works with "vanilla" OpenSceneGraph - but it will run at slightly lower framerate.

Current list of patches in this repository:

• Use single precision matrices & planes by default.
• Added option for single precision osg::Quat's (enabled by default). Similar change rejected on osg-submissions.
• Nodes with invalid bounding sphere (which you get e.g. when creating a completely empty node) are interpreted as "always culled". This type of node is common in a bone hierarchy for skeletal animation, and culling them early helps performance. Rejected on osg-submissions.
• Removed several dynamic_cast's.
• (Occasionally:) Uncontroversial bug fixes that were proposed upstream but have not been merged yet.

Planned changes: see https://github.com/scrawl/osg/issues
