Visualization plays a crucial role in molecular modeling, helping researchers and scientists better understand complex structures and their dynamics. One challenge that molecular modelers often face is presenting these models in a visually distinct and impactful way to emphasize specific components or processes. The Pulse animation in SAMSON offers a valuable, straightforward solution.
Introducing the Pulse Animation
The Pulse animation effect is specifically designed to make nodes progressively appear and disappear, bringing life and clarity to otherwise static molecular models. Rather than having components suddenly pop in or out, this effect uses smooth transparency transitions to provide a natural and engaging presentation.
This effect is particularly useful when working with molecular structures that include attributes such as transparency (e.g., structural models, visual models, meshes, or labeling). The Pulse animation makes it easy to highlight and guide viewers’ attention to specific model components—all without unnecessary visual clutter.
How to Add the Animation
To use the Pulse animation:
- Select the nodes you wish to animate. These should have a transparency attribute to visualize the effect properly.
- Open the Animation panel in SAMSON’s Animator section.
- Double-click on the Pulse animation effect to apply it to your selected nodes.
The Mechanics of the Pulse Animation
The Pulse animation adopts a 5-keyframe process:
- Keyframes 1-2: Nodes remain fully transparent.
- Keyframes 2-3: Transparency starts to decrease, and the nodes gradually become visible.
- Keyframe 3: Nodes are fully opaque (completely visible).
- Keyframes 3-4: Transparency increases, making the nodes progressively disappear.
- Keyframes 4-5: Nodes return to full transparency.
You can fine-tune the transitions by manually moving the animation keyframes. This flexibility allows you to adapt the timing and pacing to your specific visualization needs.
Refining Your Animation with Easing Curves
In addition to setting keyframe positions, you can modify how parameters transition between frames using SAMSON’s Easing curve. This feature enables further customization and control over the aesthetic and fluidity of your animation.

Why Use the Pulse Animation?
Adding the Pulse animation can elevate your presentations, whether you’re demonstrating structural models in lectures, creating visually engaging publications, or improving interactive molecular design workflows. This feature simplifies visual communication and helps audiences focus on elements that matter most in your study or project.
