* BulletSim: remove friction calcuation from BSMotor and move linear andRobert Adams2013-05-067-67/+47
| | | | | | | angular friction computation into linear and angular movement code. The friction wasn't being applied properly. This will make it so vehicles don't drift as much and the drift is tunable by changing the friction timescales.

| | | | | | | | | | | | | | to an existing shape instance. BSShapeNative rebuilds shape for all references. BSShapeCompound returns another reference copy if the compound shape already exists (for linksets).
* | BulletSim: LinksetCompound work to disable collision for root andRobert Adams2013-04-291-14/+30

| | | | | | | | The symptom was exceptions while creating physical terrain. Reduce default terrain mesh magnification to 2 from 3 because the higher resolution uses a lot of memory and doesn't solve the terrain smoothness for vehicles. Added comments here and there and improved some debugging log messages.

| | | | | | | Check for the case where the fetched mesh asset fails meshing (degenerate triangles or no physical mesh). In this case, the asset is marked 'failed' and BulletSim doesn't keep trying to fetch over-and-over trying to get a good asset.
