Detailed Description

A ScalarBar is an osg::Geode to render a colored bar representing a range of scalars. The scalar/color ranges are specified by an instance of ScalarsToColors. There are a number of configurable properties on the ScalarBar, such as the orientation, the number of labels to be displayed across the range, the number of distinct colors to use when rendering the bar, text details etc.

In summary, the main configurables on the ScalarBar are:

  1. The range of scalars represented by the bar, and the colors corresponding to this range - these are specified by the ScalarsToColors object.
  2. The number of colors used when rendering the bar geometry - this may be thought of as the bar 'density'.
  3. The number of text labels to be used when displaying the bar.

The other configurables should be self-explanatory.

Member Enumeration Documentation

◆ Orientation

ScalarBar orientation specification.

Enumerator
HORIZONTAL 

a horizontally ascending scalar bar (x-axis)

VERTICAL 

a vertically ascending scalar bar (y-axis)

Constructor & Destructor Documentation

◆ ScalarBar() [1/3]

osgSim::ScalarBar::ScalarBar ( )
inline

◆ ScalarBar() [2/3]

osgSim::ScalarBar::ScalarBar ( int numColors,
int numLabels,
ScalarsToColors * stc,
const std::string & title,
Orientation orientation = HORIZONTAL,
float aspectRatio = 0.25,
ScalarPrinter * sp = new ScalarPrinter )
inline

Construct a ScalarBar with the supplied parameters.

Parameters
numColorsSpecify the number of colors in the scalar bar. Color interpolation occurs where necessary.
numLabelsSpecify the number of labels in the scalar bar.
stcThe ScalarsToColors defining the range of scalars and the colors they map to.
titleThe title to be used when displaying the ScalarBar. Specify "" for no title.
orientationThe orientation of the ScalarBar.
See also
Orientation.
Parameters
aspectRatioThe aspect ration (y/x) for the displayed bar. Bear in mind you may want to change this if you change the orientation.
spA ScalarPrinter object for the ScalarBar. For every displayed ScalarBar label, the scalar value will be passed to the ScalarPrinter object to turn it into a string. Users may override the default ScalarPrinter object to map scalars to whatever strings they wish.
