When examining a molecular model, the structure is only part of what you need to keep track of. You may want a close-up to inspect a region, a full-document view for context, and a particular projection for a crystal. Repeatedly zooming, rotating, and repositioning the camera to move between these views can interrupt your work—and make it harder to compare what you are seeing.
In SAMSON, a practical way to handle this is to use multiple cameras in the same document. Each camera gives you a view of the visualizable objects, and only one camera is active at a time. Instead of rebuilding a view whenever you need it, you can switch to another camera that is already set up for a different perspective.
Build a small set of purposeful views
Think of cameras as saved viewpoints for different questions you ask about the same model. For example, one view might show the whole document, while another is intended for a close-up or a different projection. The useful distinction is not simply “camera one” versus “camera two”; it is the job each view helps you do.
To add a camera, choose Visualization > Camera. A new camera starts at a default position, so you can then adjust it for the view you want. Use the camera controls to navigate the viewport, and consider creating only the views that you expect to revisit. A short, useful set is easier to switch between than a collection of nearly identical perspectives.
Switch views without losing your place
When you are ready to move between perspectives, find the camera in the Document view. Double-click it, or right-click it and choose Set as active camera. The active camera is the one currently providing the viewport’s view.
This is especially helpful when you are moving back and forth between detail and context. Rather than zooming out from a close-up and later trying to reproduce it, switch to a camera prepared for the broader view. Then return to the close-up when you need to inspect the same area again. This workflow can also help when you want to keep a specific projection available alongside other views.
Use camera actions and properties deliberately
A camera’s context menu offers several useful actions. You can center it on the current selection or on the whole document, activate camera inertia for movement with inertia, switch to orthographic projection, set it as active, or move the camera. Orthographic projection can be useful for viewing crystals. These options let you adjust a camera for a particular task without treating every view as a generic perspective.
For more precise adjustments, select the camera and open the Inspector. The Inspector lets you view and modify camera properties, including position, projection, and inertia. This gives you a place to check or change the settings of a selected camera rather than relying only on viewport navigation.
Because cameras are part of a SAMSON document, they are saved and loaded with it in .sam and .samx formats. That means your document can retain its set of viewpoints when you return to it, rather than requiring you to recreate them each session.
A useful starting habit is simple: when you find yourself repeatedly returning to a particular view, add a camera for it. Keep one view for orientation and another for the detail you are studying, then switch between them as your question changes.
