For molecular modelers, keeping the focus on specific atoms or regions during animations can be a real pain point. Whether you’re monitoring a reaction mechanism, tracing a particle’s trajectory, or showcasing a dynamic simulation to your team, having the camera continuously look at selected atoms can greatly enhance your workflow. Fortunately, SAMSON provides the Look at atoms animation to solve this challenge.
Why Use the “Look at atoms” Animation?
The Look at atoms animation adjusts the camera to continuously focus on the group of atoms you selected when creating the animation. This ensures that the camera’s target moves with the geometric center of the selected atoms, while the camera’s position remains static. The result? A stable, focused view that follows key molecular events without disruptive camera movements.
This feature is particularly helpful when studying systems where you need to observe a part in motion, for example:
- Investigating the dynamic behavior of a ligand binding to its target.
- Tracking conformational changes in biomolecules.
- Presenting focused animations of molecular interactions during meetings or lectures.
How to Set It Up
Here’s how you can use the Look at atoms animation:
- Select the atoms you want the camera to track. Orient your view to position the camera as you like.
- In the Animator Track view, choose the start frame for the animation.
- Double-click on the Look at atoms animation effect in the Animation panel. The camera begins to track the geometric center of the selected atoms between keyframes.
- Define the end frame of the animation as needed.
Pro tip: You can always adjust the start and end frames later, if necessary. The system is very flexible, allowing you to refine your animation as you go.
Customizing Animation Properties
The Look at atoms animation is applied to the active camera by default. However, you can tweak its properties using SAMSON’s inspection tools:
- Apply to active camera: If you have multiple cameras, you can choose which one applies this animation.
- Keep camera upwards: This option lets you define how the animation behaves based on the active grid.
These options give you more control over how the animation will look and behave, ensuring it aligns with your visualization objectives.

Conclusion
The Look at atoms animation is an invaluable feature for molecular modelers wishing to create focused and compelling visualizations. By locking the camera’s focus on specific atoms, you’re free to showcase dynamic molecular processes without losing sight of the key details.
