Detailed Description

Maps a value from the navigation function into the range [0.

.1] and forwards the choosing of the color to its registered ColorScheme. The mapping is a 'flat-headed' saw-tooth function, where users control the period of the saw-tooth and the width of the flat sections.

Constructor & Destructor Documentation

gfx::ColorCycle::ColorCycle	(	const ColorScheme *	scheme,
		double	period,
		double	width
	)

Parameters:

period	the cycle repeats with this period (ensured to be >= epsilon)
width	the mapped value stays 0 or 1 within 'width' of N*period ('width' is trunkated to period/3)
