TextureMath() [1/2]

TextureMath::TextureMath	(	const bool	_abs,
		const bool	_clamp,
		const double	_clampMin,
		const double	_clampMax,
		const bool	_repeat,
		const double	_minRepeat,
		const double	_maxRepeat,

		const bool	_scale,
		const double	_minimalInput,
		const double	_maximalInput
	)

\ brief Initialize converter

The values are modified in the following way:
First the absolute value of the property is taken if requested (_abs)

Then this value is clamped against the given values (_clamp,_clampMin,_clampMax)

If the texture should be repeated, the values are translated such that the minimum is at min_val(0.0 by default) and than scaled such that the maximum is at max_val. This data is than passed to the rendering (_repeat,_minRepeat,_maxRepeat)

If the texture should not be repeated you could choose to center the data around 0.5. The negative values are than mapped to 0..0.5 and the positive values to 0.5..1 (_center)

Otherwise, the values are mapped directly to 0..1. You can also disable that final scaling with (_scale)

Parameters

_abs	Take absolute value?
_clamp	Clamp values?
_clampMin	Minimal clamping value
_clampMax	Maximal Clamping value
_repeat	Repeat Texture?
_minRepeat	Minimal value for repeat
_maxRepeat	Maximal value for repeat
_center	Center values?
_scale	Scale values?
_minimalInput	Minimal input value given
_maximalInput	Maximal input value given
