Function Documentation

BinarySearchLeft()

GGint BinarySearchLeft ( GGfloat const  key, GGfloat const *  array, GGint const  size, GGint const  offset, GGint  min  )

inline

Find the index of the key value in the p_array buffer.

Parameters

key	- value in p_array to find
array	- p_array where is the key value
size	- size of p_array, number of elements
offset	- apply offset when searching index (optionnal)
min	- apply a min index (optionnal)

Returns

index of key value in p_array buffer

LinearInterpolation()

GGfloat LinearInterpolation ( GGfloat const  xa, GGfloat const  ya, GGfloat const  xb, GGfloat const  yb, GGfloat const  x  )

inline

interpolate the x value between point A and B

Parameters

xa	- Coordinate x of point A
ya	- Coordinate y of point A
xb	- Coordinate x of point B
yb	- Coordinate y of point B
x	- value to interpolate

Returns

the interpolated value

LogLogInterpolation()

GGfloat LogLogInterpolation ( GGfloat  x, GGfloat  x0, GGfloat  y0, GGfloat  x1, GGfloat  y1  )

inline

log log interpolation of the x value between point (x0,y0) and (x1,y1)

Parameters

x0	- Coordinate x0 of point A
y0	- Coordinate y0 of point A
x1	- Coordinate x1 of point B
y1	- Coordinate y1 of point B
x	- value to interpolate

Returns

the loglog interpolated value
