Tracking the motion of specific parts of a molecular system during simulations can be a daunting task. Whether you’re studying a molecular binding process, structural changes, or other dynamic events, losing sight of the most crucial atoms can hinder your understanding. SAMSON’s ‘Follow Atoms’ animation can ease this challenge by enabling you to automatically track selected atoms with the camera across simulation frames.
What Is the ‘Follow Atoms’ Animation?
The ‘Follow Atoms’ animation ensures that the camera continuously follows the atoms you select. Both the camera position and target dynamically move to maintain a constant distance and orientation relative to the selected atoms. This feature is particularly handy for animating and visually capturing how specific atoms or regions of a system behave over time, such as tracing interactions or transformations in complex molecular systems.
Imagine observing your protein-ligand interaction closely, or following the dynamics of a specific functional group—all without manual camera adjustments. The ‘Follow Atoms’ animation automatically centers your view, leaving you free to focus on the science rather than camera alignment.
How to Set It Up
Setting up the ‘Follow Atoms’ animation is straightforward. Follow these steps to integrate it into your workflow:
- Select your atoms: Use the selecting tool to choose the atoms you want the camera to track.
- Orient the camera: Adjust the camera’s view and position as desired using the tools described in the camera orientation guide.
- Add the animation: Navigate to the Animator’s Track view and choose the start frame for your animation. Then open the Animation panel and double-click on the ‘Follow Atoms’ effect.
- Define behavior: The camera will adjust its position to track the geometric center of the selected atoms, maintaining the distance and angle set in the start frame. Fine-tune your animation by adjusting the end frame or dragging keyframes as needed.
Tips for Optimizing Your Animations
You can further tweak the behavior of the Follow Atoms animation:
- Inspect and tweak properties: Use the inspector to modify options such as Apply to active camera or Keep camera upwards, which adjusts behavior based on the grid status.
- Refinements: The camera target is fixed to the geometric center of the selected atoms, so you can adjust its position through the animation controllers for more precision. Learn more in the adjusting camera positions section of the documentation.

Why It Matters
This feature greatly simplifies visualization tasks in molecular modeling. It’s tailored to help researchers conduct detailed analysis by minimizing distractions and focusing attention on the system’s most crucial parts. Save valuable time and get better insights into your simulations by letting the camera work for you.
