Function Documentation

GLUSAPI GLUSfloat GLUSAPIENTRY glusMathClampf	(	const GLUSfloat	value,
		const GLUSfloat	min,
		const GLUSfloat	max
	)

Clamps a given value between a minimum and maximum value.

If the value is between min and max, the value is returned.

Parameters

value	The value to be clamped.
min	The minimum border. If the value is lower than min, min is returned.
max	The maximum border. If the value is greater than max, max is returned.

Returns

The clamped value.

GLUSAPI GLUSfloat GLUSAPIENTRY glusMathDegToRadf

(

const GLUSfloat

degrees

)

Converts degrees to radians.

Parameters

degrees

The angle in degrees.

Returns

The angle in radians.

GLUSAPI GLUSfloat GLUSAPIENTRY glusMathLengthf	(	const GLUSfloat	x,
		const GLUSfloat	y,
		const GLUSfloat	z
	)

Calculates the length of a vector or the distance of a point to the origin by providing the x, y and z coordinates.

Parameters

x	The x coordinate.
y	The y coordinate.
z	The z coordinate.

Returns

The calculated length.

GLUSAPI GLUSfloat GLUSAPIENTRY glusMathMaxf	(	const GLUSfloat	value0,
		const GLUSfloat	value1
	)

Calculates the maximum of two values.

Parameters

value0	The first value.
value1	The second value.

Returns

The maximum of the two values.

GLUSAPI GLUSfloat GLUSAPIENTRY glusMathMinf	(	const GLUSfloat	value0,
		const GLUSfloat	value1
	)

Calculates the minimum of two values.

Parameters

value0	The first value.
value1	The second value.

Returns

The minimum of the two values.

GLUSAPI GLUSfloat GLUSAPIENTRY glusMathMixf	(	const GLUSfloat	value0,
		const GLUSfloat	value1,
		const GLUSfloat	t
	)

Linear interpolation of two values.

If t = 0, value0 is returned. If t = 1, value1 is returned.

Parameters

value0	First value.
value1	Second value.
t	The fraction.

Returns

The interpolated value.

GLUSAPI GLUSfloat GLUSAPIENTRY glusMathRadToDegf

(

const GLUSfloat

radians

)

Converts radians to degrees.

Parameters

radians

The angle in radians.

Returns

The angle in degrees.
