Detailed Description

template<class Tv = real, class Tp = real>
class gam::Curve< Tv, Tp >

Exponential curve with variable curvature.

This curve will return values in the interval [start, end] starting from 0 and ending on 'end' over its length in samples. The last point is exclusive, so it takes length + 1 samples to reach 'end' inclusively. For iterations exceeding the specified length, the values returned will be unbounded.

Template Parameters:

Tv	value (sample) type
Tp	parameter type

Constructor & Destructor Documentation

Curve	(	Tp	length,
		Tp	curve,
		Tv	end = Tv(1),
		Tv	start = Tv(0)
	)

Parameters:

[in]	length	length of curve in samples
[in]	curve	curvature, c, where c > 0 approaches slowly (accelerates), c < 0 approaches rapidly (decelerates), and c = 0 approaches linearly
[in]	end	end value
[in]	start	start value
