Managing visibility in molecular animations can sometimes be a challenge for modelers aiming to illustrate complex dynamics. If you’ve ever needed nodes to appear and disappear precisely during an animation, SAMSON’s Flash animation provides a solution specifically tailored to your needs. Here, we'll explore how to use this feature effectively to bring clarity and aesthetic control to your molecular presentations.
Why Use the Flash Animation?
There are scenarios where selectively revealing or hiding molecular nodes can bring significant value to your animations. For instance:
- Highlighting a reaction site without overwhelming the viewer with background details.
- Creating engaging step-by-step visuals for teaching or presentations.
- Maintaining focus on selected regions of intricate molecular models.
The Flash animation achieves this by altering the visibility of nodes at keyframes, without affecting their transparency. This ensures a clean and professional display.
How It Works
Adding a Flash animation to your project is straightforward:
- Pick the nodes you wish to show and hide during the animation.
- Double-click the Flash animation effect in the Animation panel within the Animator.
The Flash animation is structured with 4 keyframes:
- Between keyframes 1 and 2: Nodes stay hidden.
- At keyframe 2: Nodes become visible and remain visible until keyframe 3.
- At keyframe 3: Nodes become hidden again and stay hidden until keyframe 4.
You can move these keyframes interactively to adjust the timing of the visibility transitions, which makes it easy to align the animation with your specific narrative.
Fine-Tuning Visibility Changes
To achieve smooth transitions, SAMSON offers the ability to modify the Easing curve. This feature helps define how parameters are interpolated between keyframes. Experimenting with the Easing curve allows you to add distinctive flare or dynamic pacing to your animations.
Below is an example of how the Flash animation works:

Conclusion
The Flash animation effect in SAMSON grants molecular modelers precision over node visibility. Whether breaking down complex molecular processes or zooming in on an area of interest, this is a powerful tool worth exploring.
