3D viewer
The 3D Viewport provides an interactive rendering of the physics simulation.
Mouse Controls
Interact with the 3D view using your mouse:
- Rotate: Left-click and drag to orbit the camera around the model.
- Pan: Right-click and drag to move the view vertically and horizontally.
- Zoom: Use the mouse scroll wheel to move the camera closer to or further from the model.
- Nudge: Hold Ctrl + Left mouse button to create a virtual probe for manual catheter nudging and manipulation in the viewer.
Preset Views
Buttons in the upper-right corner of the 3D viewer snap the camera to standard viewing angles. The same snaps are available from the keyboard:
| Key | View |
|---|---|
1 | Front |
2 | Back |
3 | Top |
4 | Left side |
5 | Right side |
6 | Iso |
About the preset views: The Front, Back, Top, Left, Right, and Iso presets snap the camera to standard angles, but the 3D viewer always renders in perspective projection. The presets are not true orthographic views — there is still some foreshortening, especially at the ends of long catheters. Use them for quick orientation rather than for taking measurements off the screen.
The Axes button (also in the upper-right toolbar) toggles the XYZ axis overlay on and off. There is no keyboard shortcut for the axis toggle — use the button.
Exporting the view: The catheter's current deflected shape can be exported from File → Export — either as an image (PNG/JPG) of the viewport, or as a 3D STL model for use in CAD, 3D printing, or meshing tools. See the Menu Bar page for details.
