Eos 3 is the version under development by me. It is a development based on Eos2.5. Eos 3 is different from Eos 3D, which is also being designed along the line of paper of SCSS 2017 paper. I am trying to release Eos 3.0 by the end of March 2018. Eos 3.0 runs on Mathematica 11.2. Some of the features, especially those of graphics may not work properly on on Version 10 or earlier.
