Mol*

MolSysViewer relies on a third-party project for the actual 3D rendering in the browser: Mol* (MolStar).

Mol* is not part of MolSysSuite, and we are not the authors of Mol*. We chose to build on it because it is a powerful, modern molecular viewer, and we are genuinely grateful to the Mol* developers for making it available to the community.

In practice, this is the division of responsibilities:

• Python side (your notebook): you interact with MolSysViewer and MolSysMT to load molecular data and decide what you want to see.

• Browser side (the viewer): Mol* draws the scene and handles interactive graphics.

You do not need to learn Mol* internals to use MolSysViewer productively, but it helps to know that Mol* is the engine that makes the visualization possible.
