In molecular modeling, creating compelling and informative animations can be vital to communicating complex molecular interactions. But how do you highlight specific elements or simplify visuals without losing essential context? The Conceal atoms animation in SAMSON offers a precise way to progressively hide atoms and their associated bonds, letting modelers focus attention exactly where it’s needed. Let’s explore how this works and how you can take advantage of it!
What Does ‘Conceal atoms’ Do?
The Conceal atoms animation allows atoms (and bonds between them) to disappear incrementally across multiple frames. Unlike transparency adjustments, this animation achieves the effect through the visibility of nodes. In molecular animation, this can be especially useful for presenting dynamic processes or zooming into specific molecular regions without overwhelming viewers with unnecessary details.
Adding the Animation
Here’s how you can incorporate the Conceal atoms animation into your molecular models:
- Select the atoms and bonds that you want to progressively conceal.
- In the Animation panel of the Animator, double-click on the Conceal atoms animation effect.
This animation consists of 4 keyframes:
- Keyframes 1 to 2: The selected atoms and bonds are fully visible.
- Keyframes 2 to 3: The atoms and bonds progressively disappear based on their order in the selection.
- Keyframes 3 to 4: The specified atoms and bonds are completely hidden.
You can adjust the timing of keyframes to control the speed and order of the disappearance as needed. For instance, a slower progression might emphasize a gradual reveal of the underlying structure, while quicker transitions might better suit dynamic processes.
Pro Tip: Fine-Tuning the Effect
The animation’s pacing and style are customizable using the Easing curve. This allows you to adjust interpolation properties that affect how smoothly atoms disappear between frames. A cubic easing function might emphasize gradual acceleration for effect, while linear interpolation ensures constant visibility shifts.
Applications in Presentations
This feature is highly versatile and finds use in a range of molecular presentations. For example, while showcasing a ligand entering a binding pocket, you might conceal atoms of surrounding residues sequentially to expose the active site.

Why Use ‘Conceal atoms’?
Hiding unnecessary details in molecular models saves viewers from distraction and keeps the spotlight on critical molecular interactions. Whether you’re preparing classroom materials, research presentations, or publications, this functionality simplifies visualization and enhances your communication of molecular storylines.
