In molecular modeling, efficiently presenting complex molecular structures and dynamic simulations is essential for effective communication and analysis. But what if your project requires simplifying the visualization by temporarily hiding certain molecular components while maintaining smooth transitions in animations? This is where SAMSON’s Hidden animation can make all the difference.
What Does the Hidden Animation Do?
The Hidden animation in SAMSON allows you to make selected molecular nodes completely hidden between two keyframes. Unlike manipulating transparency, this animation works directly with the visibility property of nodes, ensuring a seamless transition without any visual artifacts. It’s particularly valuable when emphasizing specific molecular regions or focusing attention on particular components during presentations or educational demonstrations.
How to Use the Hidden Animation
The process of implementing the Hidden animation is straightforward. Here’s a step-by-step guide to get you started:
- Select the molecular nodes that you want to hide during the animation.
- Navigate to the Animation panel within the Animator interface in SAMSON.
- Double-click on the Hidden animation effect. This action will create a begin keyframe at the current frame automatically.
- Adjust the animation keyframes as necessary to fit your specific needs. For example, you can control the timing and duration of the nodes’ visibility transitions.

Pro Tips for Effective Usage
Here are some additional tips to get the most out of the Hidden animation feature:
- Combine the Hidden animation with complementary animations like Shown, Appear, or Disappear to create more dynamic presentations.
- Use the Easing curve to customize how animation parameters are interpolated between frames. This control allows you to fine-tune the speed and fluidity of visibility changes.
- Check your animations in real-time to ensure that the transitions align with your storytelling or analysis goals.
Streamlining Animations in the Updated SAMSON
As a note, the Animation menu previously used in earlier SAMSON versions has been replaced by the streamlined Animation panel within the Animator interface. You can access all animations, including Hidden, directly from there. This simplifies the animation workflow and provides more intuitive controls for molecular presentations.
The Hidden animation is a game-changer for molecular modelers looking to simplify complex visuals while maintaining control over how structures are presented dynamically. Whether you’re creating tutorials, simulating experiments, or delivering a conference presentation, this feature can elevate your molecular animations.
