Molecular modeling often involves visualizing the movement of atoms or molecules to understand complex phenomena. One common pain point is accurately recording and preserving atomic trajectories during animations. This can be essential for presentations, analyses, or sharing insightful data with peers. SAMSON’s Record path animation offers a precise and efficient solution by recording atoms’ trajectories as a path.
What is the Record Path Animation?
The Record path animation in SAMSON creates tracks that log atomic movements during animations. This can be of tremendous value when combined with animations like Simulate, Assemble, and Dock. As you play through your presentation, the tool tracks each atom’s position over time clearly and efficiently.
How to Add the Record Path Animation
Adding the Record Path animation is simple:
- Navigate to the Animation panel in the Animator.
- Double-click on Record path. This will insert the animation in your timeline at the selected frame.
- Adjust the keyframe position as needed. The animation executes from top to bottom in the timeline, so place Record path after the animations it should track.
The track segments visually indicate the recording progress:
- Green: Atoms’ positions have been successfully recorded.
- Red: Positions are invalid or not yet recorded.
Fine-Tuning Performance
If you’re working on large-scale animations, enabling and disabling the recording functionality at strategic points can significantly optimize performance. To disable path recording temporarily:
- Right-click on the Record path animation in the Animator and toggle Enable recording.
- Alternatively, use the Inspector to enable or disable the recording functionality.
When recording is disabled, the animation controllers will appear darkened.
How to Export the Recorded Path
Once the Record Path animation has entirely recorded (indicated by a fully green track), you can export the path to document it:
- Open the Inspector for the Record Path animation and click Create path.
- Alternatively, right-click the animation in the Animator and select Create path.
Exporting paths allows you to save valuable trajectory data for further visualization or sharing with your team.
Conclusion
The Record path animation makes it easy for molecular modelers to document and visualize atomic movements. By combining it with other key animations and leveraging its robust recording features and export options, you can comprehensively present your molecular simulation workflows.
