Member Function Documentation

crossProduct()

float CiColor::crossProduct ( CiColor  p1, CiColor  p2  )

static

Parameters

p1	point one
p2	point tow

Returns

the cross product between p1 and p2

getClosestPointToPoint()

CiColor CiColor::getClosestPointToPoint ( CiColor  a, CiColor  b, CiColor  p  )

static

Parameters

a	reference point one
b	reference point two

isPointInLampsReach()

bool CiColor::isPointInLampsReach ( CiColor  p, CiColorTriangle  colorSpace  )

static

Parameters

p	the color point to check

Returns

true if the color point is covered by the lamp color space
