One of the essential tasks for a molecular modeler is visualizing and analyzing complex molecular structures in motion. Whether you’re exploring conformational changes or simply preparing an engaging presentation, being able to animate molecular systems effectively is crucial. A specific pain point often arises when you need to rotate a group of particles precisely around its geometric center. Fortunately, SAMSON provides a simple yet powerful tool to tackle this: the Rotate animation feature.
Why Use the Rotate Animation?
The Rotate animation in SAMSON allows you to rotate a group of particles around their centroid. This is particularly useful when you’re analyzing symmetrical structures, simulating motion, or creating visualizations for presentations. By rotating molecules smoothly, you can better comprehend their spatial arrangements and dynamic properties. It also helps you convey crucial information about molecular behavior to your audience, whether they’re colleagues or students.
What makes this feature even more user-friendly is that the rotation axis is predefined: it is collinear with the Z-axis and passes through the geometric center of the particles being animated. Effective, predictable, and straightforward.
How to Add a Rotate Animation
If you’re eager to bring your projects to life, adding a rotation effect is quick and intuitive:
- Select the particles: Begin by selecting a group of particles that you want to rotate. You can use SAMSON’s selection tool for this step.
- Add the animation: In the Animation panel, double-click on the Rotate animation effect. This will automatically apply the rotation to your selected particles.
- Adjust keyframes: Your animation will span two keyframes by default. You can freely move these keyframes to control the timing and duration of the rotation. This flexibility lets you fine-tune how your animation unfolds.
Tips for Fine-Tuning
The Rotate animation can be further adjusted using SAMSON’s Easing curve. This allows you to control how smoothly the rotation progresses between keyframes, making your animations more engaging and professional-looking.

What to Keep in Mind
It’s important to note that SAMSON has evolved, and some interface elements featured in earlier tutorials may have changed. For instance, while the Rotate animation can no longer be accessed from the Animation menu, it is readily available in the Animation panel of the Animator. This streamlined approach enhances accessibility and ensures all animations are within easy reach.
Conclusion
The Rotate animation in SAMSON is an elegant solution for showcasing molecular rotations, whether for analysis or presentation purposes. Its ease of use, coupled with customization features, makes it a valuable addition to any molecular modeler’s toolkit.
