Detailed Description

(Preview feature) [Medical] Shape node to display a dynamic scale bar in window coordinates.

This class displays a 2D scale bar. The position of the scale bar is specified in normalized screen coordinates (-1 to 1). By default, the length of the scale bar is a fixed distance in normalized screen coordinates. However if the trackedCamera field is set, then length is a distance in 3D world coordinates and the the size of the scale bar on screen is computed based on that distance. For example, if the application is viewing DICOM data measured in millimeters (mm), then setting length to 100 displays a scale bar that shows the distance 10 cm on screen. The scale bar size will change if the camera is zoomed in or out (camera height field changes).

The distance computation is based on "horizontal" or "vertical" relative to the camera, so the scale bar adjusts automatically if the camera is rotated to view a different volume axis, e.g. Coronal vs Axial.

This class is not intended to replace the MeshViz axis classes for general 2D data plotting. This class has only been tested with SoOrthoSlice and an SoOrthographicCamera (the usual case for medical image viewing).

Member Data Documentation

◆ alignment

SoSFEnum SliceScaleBar::alignment

Scale bar alignment (default is CENTER).

Definition at line 125 of file SliceScaleBar.h.

◆ label

SoSFString SliceScaleBar::label

Label (default is empty string).

Definition at line 128 of file SliceScaleBar.h.

◆ length

SoSFFloat SliceScaleBar::length

Length in normalized screen coordinates (-1 to 1) if not tracking, else length in 3D world coordinates.

Default is 1.

For example, if the application is viewing DICOM data measured in millimeters (mm), then setting length to 100 displays a 10 cm scale bar on screen.

Definition at line 105 of file SliceScaleBar.h.

◆ numTickIntervals

SoSFInt32 SliceScaleBar::numTickIntervals

Number of tick intervals (default is 0).

If numTickIntervals is 0, no tick marks are drawn. For example, if the length is set to 100 mm, then set numTickIntervals to 10 to get a tick mark every 10 mm (1 cm).

Definition at line 112 of file SliceScaleBar.h.

◆ orientation

SoSFEnum SliceScaleBar::orientation

Scale bar orientation (default is HORIZONTAL).

Definition at line 122 of file SliceScaleBar.h.

◆ position

SoSFVec2f SliceScaleBar::position

Position in normalized screen coordinates (-1 to 1).

Default is (0,0,0).

Definition at line 96 of file SliceScaleBar.h.

◆ trackedCamera

SoSFNode SliceScaleBar::trackedCamera

Tracked camera (default is null).

This should be the camera that is viewing the tracked scene. It will be used to determine the length of the axis in NDC based on the specified length in 3D world coordinates.
