Are there plans for making Coin multi-thread safe?
Coin will probably never be 100% thread safe, but in Coin 2.0 we’ve added support for thread safe rendering. This means that you can render a scene graph using many threads, at the same time. The application programmer is responsible for all thread synchronization though, but we’ve added many thread classes to make this easier for you (SbMutex, SbRWMutex, SbStorage, SbBarrier, …).
