When working on molecular modeling projects, being able to zoom in and focus on specific structural features is vital. This is where SAMSON’s Dolly Camera animation comes into play. If you’ve ever struggled to create dynamic zoom effects that adjust the camera’s viewpoint smoothly while maintaining focus on different target points, you’ll find this feature particularly useful.
The Dolly Camera animation ensures that your camera’s position and target point are adjusted fluidly between specific frames of your animation. Unlike the Zoom Camera animation, which retains a single target point, the Dolly Camera supports multiple target adjustments—ideal for exploring different molecular regions. For example, if you’re trying to emphasize changes in a molecular system’s active site while keeping visual effects like fog and depth-of-field intact, this feature does the heavy lifting.
How to Add a Dolly Camera Animation
Creating a Dolly Camera animation in SAMSON is straightforward. Here’s how you can do it:
- Begin by navigating to the Animator’s Track view to select and set the start frame of your animation.
- Adjust the camera’s orientation to your desired perspective by manipulating the view, as detailed here.
- Next, double-click on the Dolly Camera effect located in the Animation Panel of the Animator. Set the end frame based on how long you want the animation to last.
Pro Tip: You can always fine-tune the start and end frames later to alter the animation duration dynamically.

Customizing Properties for Better Results
New to the Dolly Camera animation? By default, the effect applies to the active camera (i.e., the current viewpoint center). The target point—a key property of the animation—is initially set to the current center of the view. But that’s not all.
You can go a step further and tweak the animation properties for more control:
- Target Adjustment: Use the provided animation controllers to modify the camera’s target points and positions. This ensures the molecular segments you wish to highlight stay in focus.
- Easing Curve: Navigate to the easing curve settings to fine-tune how the camera parameters transition between frames. This makes animations feel more natural and fluid.
- Grid Dependency: You can customize the behavior of the camera depending on whether the grid is on. Adjust the Keep Camera Upwards option for consistency between grid states. Learn about inspecting animations here.
Why Use Dolly Camera Animation?
The Dolly Camera’s precision and flexibility make it an essential tool for molecular modelers who need detailed and visually impactful animations. Whether you’re highlighting specific ligand-binding areas or visually communicating the spatial dynamics between molecular components, this feature saves time and enhances presentation quality.
