As a molecular modeler, one of the recurring challenges you may face is effectively presenting the dynamic behavior of molecules and their intricate structures. Imagine a presentation in which you progressively hide certain parts of your molecular system to keep your audience focused on specific regions or information. The Conceal Atoms animation in SAMSON was designed precisely for such needs, allowing you to make atoms and bonds disappear smoothly between animation frames.
What Is the Conceal Atoms Animation?
The Conceal Atoms animation gradually hides selected atoms and bonds over time by altering their visibility. This subtle effect helps maintain clarity and visual organization in your presentations. Not to be confused with transparency adjustments, this animation simplifies complex structures by directly controlling visibility.
When to Use This Effect
This tool is especially valuable when you need to:
- Prepare molecular sequences to focus on specific regions of interest.
- Clarify a crowded molecular environment by progressively removing less relevant areas.
- Create attention-grabbing animations for educational or research presentations.
Let’s take a closer look at how you can utilize this effect effectively within the SAMSON interface.
Adding the Animation
Applying the Conceal Atoms animation is straightforward:
- Select your atoms and bonds: Identify the specific parts of the molecular structure you wish to progressively hide.
- Activate the effect: Double-click on the Conceal Atoms effect inside the Animation panel of the Animator. This will generate a default setup with four keyframes.
The animation works as follows:
- Between keyframes 1 and 2: All selected atoms and bonds remain fully visible.
- Between keyframes 2 and 3: A progressive concealment effect begins, hiding the selected atoms and bonds sequentially based on their order in the selection.
- Between keyframes 3 and 4: The selected atoms and bonds are completely hidden.
You can always adjust the placement of these keyframes to control the timing and synchronization of the animation.
Customizing the Animation
The Conceal Atoms animation provides additional customization through its Easing Curve, which determines how smoothly the parameters are interpolated between frames. By adjusting the easing curve, you can create animations that feel linear, slow, or more dynamic depending on the desired effect.
See It in Action
Still not sure how it would look in practice? Here’s a quick example of the Conceal Atoms animation, combined with its counterpart, Reveal Atoms:

These animations are perfect for highlighting molecules incrementally or focusing on specific segments during a molecular presentation without overwhelming the audience.
Keep Innovating
The Conceal Atoms feature provides an elegant way to declutter complex molecular visuals and focus attention on the most critical parts of your molecular design.
