Module Description

The Measurements module allows you to add 3d rulers, 3d angle widgets, or a 2d affine transform editor widget to the 3D window.

Usage

Examples, Use Cases & Tutorials

• Attach end points of the widgets to models or volume slices to measure distances and angles
• Useful for measuring tumor diameters
• When you add a new angle or affine transform widget, you have to click once in the 3D window to render the transform widget, and three times to place the angle widget end points. After that, you can move the widgets around by dragging the handles.
• In order to get the end points of the ruler or the angle to move along a selected model surface, you currently need to rotate the view so that the handle is rendered on top of the model, the next click will snap it to the model surface. If you move the model or slice plane, the measurement point won't move with it, the constraint only works when moving the end point handle. If you make the model or slice invisible, the end point cannot be moved, as the constraint will always be false.
• Some features are not available unless Slicer3 is compiled with VTK5.4 or higher.
