For molecular modelers navigating complex structures, clear visualization of key elements is crucial. To streamline this process, SAMSON offers the Flash animation feature, a powerful tool that controls the visibility of nodes, making them appear or disappear seamlessly during an animation timeline. In this post, let’s explore how this feature can save time and enhance visual clarity for your molecular designs.
The Value of Flash Animation
When working on molecular models, it’s often necessary to highlight specific elements while hiding others. This could be for presentations, tutorials, or simply to focus your analysis on particular regions. Using transparency adjustments alone can be cumbersome and sometimes visually less effective. Here’s where the Flash animation shines—it adjusts node visibility by toggling between states of hidden and visible without relying on levels of transparency.
How Flash Animation Works
The Flash animation effect works within an animation sequence by utilizing keyframes. This predefined setup ensures your selected molecular nodes behave predictably and consistently throughout your animation. The feature includes the following key functionalities:
- Between keyframes 1 and 2: Nodes remain hidden.
- At keyframe 2: Nodes become visible and stay visible between keyframes 2 and 3.
- At keyframe 3: Nodes become hidden again and remain so between keyframes 3 and 4.
Need to emphasize certain atoms during a reaction step and hide them once their role is complete? The Flash effect is your go-to choice for creating such animations with ease.
Adding the Flash Animation
Here’s how you can use the Flash animation in your workflow:
- Select the nodes (molecules, atoms, or structures) you want to make visible or hidden during the animation sequence.
- Double-click the Flash animation effect in the Animation panel of the Animator tool.
- Adjust the 4 keyframes to customize when nodes should be visible or hidden during the timeline.
Visual control has never been more intuitive, allowing you to highlight what matters most at precise moments of your animation.
Fine-Tuning Animations
To add an extra layer of customization, Flash animation lets you modify parameters through the Easing curve. Easing curves allow interpolations between keyframes to be smooth and visually pleasing, giving your animations a polished look.

Conclusion
The Flash animation feature in SAMSON provides molecular modelers with a highly efficient way to control the visibility of nodes during animations. Whether presenting data, running simulations, or simply organizing your workflow, this tool ensures you can focus on what matters most.
