In molecular modeling, conveying clarity in presentations or simulations can sometimes be a challenge. Whether you're illustrating intricate molecular interactions for a research paper or creating visual aids for a presentation, making your models dynamic and comprehensible is a powerful tool. Enter the Pulse animation effect in SAMSON, a feature designed to help molecules 'breathe', enhancing interpretability for your audience.
The Pulse animation effect offers a unique way to progressively highlight and hide specific molecular nodes—like structural models, meshes, or even labels—in your visualizations. Thanks to its ability to manipulate transparency dynamically, the Pulse animation can make complex molecular structures easier to follow, particularly when showcasing overlapping elements. This is especially helpful in crowded molecular assemblies, where identifying specific components is crucial.
How to Add the Pulse Animation
Applying the Pulse animation is refreshingly straightforward. Here’s a quick guide:
- Select the node(s) that you wish to animate, ensuring that they have a transparency attribute.
- Access the Animation panel within the Animator tool.
- Double-click on the Pulse animation to apply it to your selected node(s).
One strength of this feature lies in its predefined keyframes, designed to provide a seamless animation experience:
- Keyframes 1 to 2: Fully transparent nodes.
- Keyframes 2 to 3: Nodes gradually decrease their transparency, becoming visible.
- Keyframe 3: Nodes are fully opaque.
- Keyframes 3 to 4: Nodes progressively increase transparency, disappearing again.
- Keyframes 4 to 5: Back to fully transparent nodes.
You can reposition these keyframes to customize the animation sequence timing as per your preferences.
Fine-Tuning with Easing Curves
Pulse animations become even more versatile when you manipulate how the transparency transitions unfold over time. This is where Easing curves come into play. By adjusting the interpolation between keyframes, you can introduce slower, faster, or non-linear progressions in transparency changes, making animations feel natural and tailored to your storytelling needs.
For example, if a structure’s reveal is meant to surprise or dramatize a process, a sharp easing curve might be preferred. On the other hand, gradual transitions can evoke steadiness and continuity, useful in presentations where subtlety is desired.

Why Use the Pulse Animation?
For molecular modelers, the Pulse animation offers a simple but valuable method for emphasizing specific elements without overwhelming viewers with excess detail. Its gradual appearance and disappearance feature is especially useful for presentations, animations, or education, making complex systems visually digestible.
