Detailed Description

A two-dimensional point.

MbFloatPoint class is used to present a point on the plane, as a similar MbCartPoint class which has a higher tolerance of representation. MbFloatPoint has a data structure which consists of a pair of numbers with a single precision floating point (float). It is used in the polygon (MbPolygon) to approximate two-dimensional curves.

Member Function Documentation

IsSame()

bool MbFloatPoint::IsSame ( const MbFloatPoint &  other, double  accuracy  ) const

inline

Are the objects equal?

The objects are equal if their data are equal with a given accuracy.

Parameters

[in]	other	- The object to compare.
[in]	accuracy	- The accuracy to compare.

Returns

Whether the objects are equal.
