Regarding collision of rigid bodies.

[fluidkocy]

Where can I find documentation on "collisionObjectType"?
If you have it, please give me the url.
If not, please tell me the difference between the "collisionObjectType" numbers.

SPlisHSPlasH uses the library PositionBasedDynamics for the simulation of the rigid bodies. There you also find the documentation:

https://positionbaseddynamics.readthedocs.io/en/latest/file_format.html#rigidbodies

PositionBasedDynamics also reads the same scene file and picks out all relevant information. Therefore, you can use all keys of the PositionBasedDynamics scene files.
