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:

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

The other configurables should be self-explanatory.

Member Enumeration Documentation

◆ Orientation

enum osgSim::ScalarBar::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

Default constructor.

◆ 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

numColors	Specify the number of colors in the scalar bar. Color interpolation occurs where necessary.
numLabels	Specify the number of labels in the scalar bar.
stc	The ScalarsToColors defining the range of scalars and the colors they map to.
title	The title to be used when displaying the ScalarBar. Specify "" for no title.
orientation	The orientation of the ScalarBar.

See also: Orientation.

Parameters

aspectRatio	The aspect ration (y/x) for the displayed bar. Bear in mind you may want to change this if you change the orientation.
sp	A 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.
