[Opensim-users] whats difference between BulletSimN vs BulletSim

[Mister Blue]

The note in OpenSim.ini.example is wrong as BulletSimN has been wrapped
into the one implementation of BulletSim. I will update the note in the ini
file.

BulletSim has two parts: C# code that implements virtual world things
(linksets, phantom objects, ...) using a physics engine and then the actual
physics engine. For the physics engine, BulletSim has two version of the
Bullet physics engine available: a C++ version (good for general use and
high performance) and a C# version (good for debugging and/or use on
platforms that don't support the Windows or Linux C++ binaries).

Originally the two versions were separate but now they have been wrapped
together. The selection of the C++ or C# Bullet physics engines is an INI
file setting. An example of what to set is in OpenSimDefaults.ini in the
[BulletSim] section.
