You should obtain a valid license from raisim.com to use files in 'rasim' and 'doc' folder.
Along with the license, we send an activation key, which is a plain text file. Before using any raisim functionality, you can activate raisim using "raisim::World::setActivationKey()"
Source codes in cmake, scripts, examples, raisimGymTorch, raisimMatlab, raisimPy, and raisimUnity (available at https://github.com/raisimTech/raisimUnity) directories are distributed under MIT <https://choosealicense.com/licenses/mit/>_ License.
Feel free to modify them for your project.
Files in rsc and thirdParty are opensource and corresponding licenses can be found inside each folder.
