In the world of molecular modeling, clear visual communication is key. Imagine needing to highlight specific molecular elements for a presentation or simulation—what if you could progressively show or hide these structures with an elegant pulsing effect? The Pulse animation in SAMSON is here to help, allowing you to make structures fade in and out smoothly. Here’s how it can enhance your molecular design workflow.
The Core Idea: Elegant Transitions for Transparency
The Pulse animation effect targets nodes with transparency attributes, such as structural models, visual models, meshes, and labels. What makes Pulse stand out is its ability to progressively transition structures from fully transparent to opaque, and back to transparency. This ensures a smooth, visually appealing way of emphasizing or de-emphasizing critical molecular features. This can be particularly helpful in education, collaborative reviews, or scientific presentations.
How to Use the Pulse Animation Effect
To utilize the Pulse animation, follow these steps:
- Identify the nodes you want to make appear and disappear progressively.
- Double-click the Pulse animation effect located in the Animation panel of the Animator.
The animation consists of five keyframes:
- Between keyframes 1 and 2, the nodes will remain fully transparent.
- Between keyframes 2 and 3, the nodes will progressively become opaque as transparency decreases.
- At keyframe 3, the nodes will be fully opaque.
- Between keyframes 3 and 4, the nodes will gradually return to transparency.
- Between keyframes 4 and 5, the nodes will reset to complete transparency.
You can freely move these keyframes to match your desired timeline—the flexibility ensures you have full control over the animation duration and synchronization with other elements in your project.
Customizing Interpolations with Easing Curves
For even greater control over your animations’ appearance, you can modify the easing curves. This feature lets you fine-tune the interpolation between keyframes to create natural, polished animations. For example, you might wish for a softer fade-in effect or a sharper fade-out for emphasis. Dive into the Inspector panel to adjust the settings and experiment with different easing options to get the desired effect.

Why Use Pulse?
The Pulse animation is an excellent choice for molecular visualizations where transitions need to draw attention subtly and effectively. Whether you’re demonstrating protein structures, illustrating molecular interactions, or emphasizing specific regions of a model, Pulse sets the stage for a clear and captivating presentation.
