Source of Air3D example ground truth value function

[ekaradon-Alexander]

In Air3D example, DeepReach prediction of value function is compared with a ground truth from the Level Set Toolbox (LST).

I am aware that LST is slow and it may take a long long time to compute a 3D value function on a 101*101*101 grid, so the authors provide a result (analytical_BRT_air3D.mat on Google Drive). Maybe it would help to make your work more solid if you could also provide the Matlab source code to produce analytical_BRT_air3D.mat. Anyhow, we hope the ground truth have a clear source.
