When working on molecular models, there are times when you need to focus on certain elements while temporarily hiding others. Adjusting these visibilities manually across different frames can be time-consuming and prone to errors. The Hidden animation in SAMSON provides an effective solution to this challenge by automating transitions in visibility during animations.
What Does the Hidden Animation Do?
The Hidden animation allows nodes within your molecular models to vanish between two keyframes. Unlike adjusting transparency settings, this animation directly modifies node visibility, ensuring they are completely hidden for the specified duration.
This feature is particularly useful for presentations or simulations where specific components of a molecular system become irrelevant or distracting during certain sequences. For instance, you can hide background structural elements while showcasing active sites in a molecular reaction.
How to Add the Hidden Animation
Adding the Hidden animation effect in SAMSON is straightforward:
- First, choose the nodes that you wish to hide during your animation.
- Next, double-click the Hidden animation effect in the Animation panel of the Animator. The system will automatically set a begin keyframe at the current frame.
- Adjust the begin and end keyframes to define the duration during which the nodes will remain hidden.
Thanks to the flexibility of the animation panel in SAMSON, you can always revisit and adjust these keyframes as per your requirements.
Fine-Tuning Visibility Transitions
SAMSON provides additional control to make your animations smoother and more visually appealing. By modifying the easing curve, you can customize how parameters transition between frames. This ensures you have precise timing control for hiding your molecular nodes, leading to more polished presentations.
From Concept to Visualization
Animations like Hidden can transform your molecular modeling workflows. Instead of manually toggling node visibility for each frame, you can now streamline the process and focus on visual storytelling. Whether you’re showcasing drug interactions, molecular dynamics simulations, or structural intricacies, features like this enhance the overall clarity and impact of your presentations.
