Managing the visibility of molecular nodes efficiently in animations can be a challenging task for molecular modelers. Whether you’re preparing a presentation or crafting visually compelling simulations, the Flash animation effect in SAMSON offers a simple yet powerful solution.
Why Use Flash Animation?
The Flash animation is a specialized feature that allows you to make nodes appear and disappear during keyframes of your animation. Instead of altering the transparency of the nodes, this effect directly toggles their visibility, which can help maintain a cleaner and more structured animation workflow within the molecular design platform.
How to Apply the Flash Animation
Here’s a step-by-step guide to applying the Flash animation in your project:
- Select the nodes: Identify the nodes you want to show or hide through the animation process.
- Add the Flash effect: Double-click on the Flash animation effect in the Animation panel of the Animator.
- Understand the four keyframes:
- Keyframes 1–2: The selected nodes remain hidden.
- Keyframe 2: The nodes become visible. Between keyframes 2–3, they stay visible.
- Keyframe 3: The nodes become hidden again. Between keyframes 3–4, they remain hidden.
- Adjust the keyframes: Position and fine-tune your keyframes based on the desired timing and flow of your animation.
By using this simple process, you can create clean transitions for nodes, adding clarity and focus to your animations. Furthermore, you can always reposition the keyframes to suit evolving project needs.
Refining the Animation with Easing Curves
To customize how the transitions between keyframes occur, you can modify the Easing curve. This setting determines how parameters are interpolated between frames, allowing you to create smoother or more pronounced transitions, depending on your requirements.
The Flash animation’s options can be accessed and adjusted via the Inspector interface and are designed to give you full control over the behavior of node visibility during the animation.

Example in Action
The practicality of the Flash animation can best be seen in this example:

Notice how the nodes transition between visible and invisible states seamlessly, making it particularly useful for presentations or simulations where specific elements need to be highlighted or concealed at timed intervals.
Conclusion
If efficient and clear control over node visibility is part of your molecular modeling workflow, the Flash animation effect is an invaluable tool. To dive deeper into its functionalities and explore additional options, visit the official documentation page.
