If you’ve ever created molecular models for presentations or publications, you’ve probably encountered this common frustration: jagged edges that ruin an otherwise beautiful visualization. You’re not alone. One of the frequent complaints among molecular modelers is the aliasing effect—rough or pixelated edges—that distracts from the clarity of molecular structures. Fortunately, there’s a straightforward solution inside SAMSON: Anti-Aliasing.
What is Anti-Aliasing?
Anti-aliasing is a graphics technique that removes the jagged appearance of diagonal lines and curved edges. In molecular visualization, it improves the clarity and elegance of structures, making sure that focus remains on the molecular system—not on visual artifacts.
How It Works in SAMSON
In SAMSON, you can control anti-aliasing through the Preferences panel by navigating to Rendering > Anti-aliasing. The user-friendly settings allow you to adjust various parameters depending on your GPU capabilities and the quality you need.
Settings Overview
- FXAA (Fast Approximate Anti-Aliasing): Efficient and suitable for most modern graphics cards. Great for general-purpose smoothing without a heavy performance hit.
- Multisampling Factor: Determines how many samples are taken per pixel. Higher values result in smoother images at the cost of rendering speed.
Why It Matters
Scientific communication often depends as much on clarity as it does on precision. Whether you’re preparing an image for a research article, a poster, or even a grant application, anti-aliasing helps ensure that your structure appears polished and easier to interpret.

Balancing Quality and Performance
Keep in mind that high levels of anti-aliasing can place more demand on your GPU. If you’re working with a large molecular system or using an older graphics card, selecting a lower setting or disabling FXAA might help maintain interactivity during exploration. Try switching between the “Best speed” and “Higher quality” presets to find the right compromise for your system.
Quick Tip 💡
You can toggle anti-aliasing on or off quickly using the Visualization > Options menu. This is especially useful when you want to work in “fast mode” and preview in high quality only just before exporting an image.
Final Thoughts
Small enhancements like anti-aliasing make a big difference in how effectively models communicate your research. Try adjusting the settings in your next visual and see the improvement for yourself.
