One of the recurring challenges for molecular modelers is effectively presenting complex molecular systems. How can you focus your audience’s attention on specific nodes or components of a structure without overwhelming them? The Pulse animation in the SAMSON integrative molecular design platform provides an elegant solution to this common problem by allowing nodes to fade in and out progressively, creating a dynamic and visually captivating presentation.
The Pulse animation can work wonders when applied to nodes with the transparency attribute, such as structural models, visual models, meshes, or labels. Whether you are showcasing molecular mechanisms or highlighting parts of a model, this effect can make your message much clearer.
Getting Started with the Pulse Animation
Applying the Pulse animation in SAMSON is an intuitive process:
- Select the nodes you wish to animate. These nodes should support transparency.
- Double-click on the Pulse animation effect located in the Animation panel within the Animator. This will add the Pulse animation to the selected nodes.
The Pulse animation uses five keyframes to control the transparency of the nodes:
- Keyframes 1 to 2: Nodes are fully transparent.
- Keyframes 2 to 3: Nodes progressively appear by decreasing their transparency.
- Keyframe 3: Nodes are fully opaque (no transparency).
- Keyframes 3 to 4: Nodes progressively disappear by increasing their transparency.
- Keyframes 4 to 5: Nodes are fully transparent.
As you assemble your animation, you can move these keyframes based on the timing and effect you wish to achieve.
Adding a Custom Touch: Adjusting Properties
For further customization, SAMSON allows you to modify how the animation transitions between keyframes using the Easing curve. This lets you achieve smooth and natural movements that can enhance the effectiveness of your Pulse animation.
Below is an example of the Pulse animation in action.

Why Use the Pulse Animation?
The Pulse animation is particularly useful for drawing attention to certain parts of your molecular structures in presentations or educational contexts. This effect can reduce distractions, clarify key points, and make your visualizations more engaging, helping your audience focus on what matters the most.
If you’re ready to bring your molecular designs to life and communicate your findings more effectively, the Pulse animation is a great tool to explore. To learn more about using this animation effect, visit the official documentation page.
