As molecular modelers, we often face the challenge of creating clear and engaging presentations for our work. In animations, particularly those depicting molecular changes or processes, control over visibility is a key factor. Enter the Shown animation in SAMSON, a powerful yet simple tool designed to make managing node visibility between keyframes intuitive and efficient.
Why Visibility Control Matters
When illustrating molecular interactions or changes, it’s crucial for certain elements of a structure to appear at the right time. But toggling visibility manually can be tedious and risk missing key details. The Shown animation in SAMSON addresses this by allowing you to control the appearance of nodes based on visibility rather than transparency. This ensures a precise and efficient way to highlight molecular elements exactly when needed.
How to Use the ‘Shown’ Animation
Getting started with the Shown animation is straightforward:
- First, select the nodes you want to make visible during the animation.
- Next, navigate to the Animation panel in the Animator and double-click the Shown animation effect. This action sets a begin keyframe at the current frame automatically.
- Finally, move the keyframes as needed to control the timing of visibility changes throughout the animation.
What sets the Shown animation apart is its flexibility. At any point, you can move keyframes to refine the animation and ensure visibility aligns perfectly with your narrative.
Enhancing Control: Fine-Tuning with Easing Curves
Another advantage of the Shown animation is the ability to fine-tune node visibility transitions using Easing curves. These curves allow you to define how parameters are interpolated between frames, providing a more dynamic and polished look to your animations.
Examples in Action
Below is an example of how the Shown animation works. The image demonstrates the Shown and Hidden animations in use, providing a clear depiction of their effect on node visibility.

Access Animations Easily
Note that the Shown animation, along with all other animation effects in SAMSON, can now be accessed via the Animator. While previous versions of the platform included an Animation menu, this feature has been streamlined into the Animation panel for ease of use.
Conclusion
The Shown animation is a versatile and practical feature for molecular modelers looking to enhance their visual presentations. By enabling precise control over visibility between keyframes, this tool simplifies the animation process while improving clarity and impact.
