When creating scientific presentations with molecular animations, one common challenge faced by molecular modelers is how to integrate context — such as presentation slides or background visuals — directly into the animation. Switching between external slide decks and SAMSON can break the flow and reduce coherence. Fortunately, SAMSON’s Set background animation offers a smooth solution.
This feature allows you to embed background changes right into your molecular presentation, ensuring continuity and visual integration. Whether you want a clean whiteboard-style background or an informative research slide behind your molecule, it’s all possible within SAMSON’s Animator tool.
Why use background animations?
Integrating backgrounds has a few practical advantages:
- Contextual clarity: Add explanations, titles, or references behind molecules to make your animations more descriptive.
- Fewer interruptions: Keep your entire presentation in SAMSON instead of switching between apps.
- Visual transitions: Background interpolations provide a smooth visual experience rather than hard cuts between frames.
How it works
To add a background animation in SAMSON:
- Open the Animation panel of the Animator.
- Double-click on the Set background animation effect.
- A keyframe is created at the current point in your timeline where the background will be set.
- You can move the keyframes if needed to adjust timing.
The background can be either a color or an image. If you choose an image, you can configure whether it should be contained (entire image visible, may leave borders) or cover (image spans fullscreen but might be cropped).
Smooth background transitions
If you specify multiple Set background animations across your timeline, SAMSON will automatically interpolate between the backgrounds. This means you’ll get a smooth visual transition from one slide to the next instead of a jump cut. To fine-tune this transition, you can use an Easing curve in the Inspector, which controls the speed profile of the interpolation.
Tips for impactful background use
- Use backgrounds sparingly: don’t overwhelm the molecule with too much information.
- Try subtle gradients or scientific imagery that adds thematic relevance.
- Use background transitions strategically to signal topic changes.
With minimal effort, you can turn a standard animation into a polished visual story that resonates more with your audience.
