Function Documentation

template<typename T >

wge::GLType< T >::Type WDataTexture3DScalers::scaleInterval	(	T	value,
		T	minimum,
		T	maximum,
		double	scaler
	)		[inline]

Scales the specified value to the interval [0,1] using m_min and m_scale.

As the method is inline, the additional parameters are no problem.

Parameters:

value	the value to scale
minimum	the min value
maximum	the max value
scaler	the scaler

Returns:

the value scaled to [0,1]

Notes:

Most integral types need to be scaled. See WGETypeTraits.h for details.

Returns:
