For researchers and molecular modelers, analyzing trajectories and exploring conformational changes can often be a tedious process. Fortunately, SAMSON’s Play Path animation offers a straightforward yet powerful solution to streamline this task by visually playing molecular paths between two frames. Whether you’re investigating dynamic behaviors, cycling between conformations, or analyzing intricate motion trajectories, this feature can simplify your work.
What Does the Play Path Animation Do?
The Play Path animation in SAMSON allows users to animate single or multiple paths between two frames. In molecular modeling terms, a path typically corresponds to a trajectory or a conformational sequence. With this feature, you can essentially “watch” the molecule’s transitions or dynamics in a smooth and synchronized animation. What’s more, if you select multiple paths, they will be synchronized for better comparability.
How to Add and Use the Play Path Animation
Adding the Play Path animation effect is intuitive:
- Select the path you want to animate. Paths are stored in SAMSON’s path nodes, which represent trajectories.
- Double-click the Play Path animation effect in the Animation panel of the Animator. The entire path will be played between two keyframes.
- Adjust the positioning of keyframes as needed to align the animation with your desired timeline. Keyframes can be easily moved at any point.
Here is an example of the Play Path animation in action:
Customization Options: Smoothing and Easing Curves
Two features add flexibility to the Play Path animation:
- Smoothing: If the number of animation frames doesn’t match the number of trajectory frames, SAMSON automatically smooths the path for a seamless effect. If you prefer a raw representation without smoothing, you can disable this feature in the Inspector.
- Easing Curves: Alter how parameters are interpolated between frames by adjusting the Easing curve. This enables finer control over the pacing and smoothness of your animation to match your specific needs.
Why Use Play Path Animation?
Whether visualizing molecular conformational flexibility or animating a simulation trajectory, the Play Path animation creates an intuitive visual narrative of your molecular systems. This can be particularly valuable when presenting your results to colleagues, conducting hypothesis testing, or simply analyzing the dynamics of molecules in detail.
