Inheritance diagram for col::lessByAngle:

## Public Member Functions | |

lessByAngle (int xValue, int yValue, vector< Pnt3f > &pointVector) | |

bool | operator() (int i1, int i2) const |

## Public Attributes | |

int | x |

points will be projected onto that plane | |

int | y |

vector< Pnt3f > & | point |

the points themselves; the () expects to get 2 indices into this array |

**Returns:**- True if point[i1] < point[i2] compared by angle, flse otherwise.

`x`

axis are computed, and those are compared. This functor is meant as a Binary Predicate for `sort()`

.Angles are in [0,360). No trigonometric function are evaluated, and if the two points are in different quadrants, then only comparisons are made, i.e. / quadrant(p1) < quadrant(p2), p1,p2 in different qu's p1 < p2 <=> | \ p1_y/p1_x < p2_y/p2_x , p1,p2 in same quadrant

**Precondition:**`x`

,`y`

, and`point`

,npoints are set.

**Implementation:**- The functor could return -1/0/+1 for less-than/euqal/greater-than. The original of this function is opyCompPointsByAngle in Y.
