Detailed Description

Three-dimensional vector.

Three-dimensional vector as data type is similar to MbVector3D, however based on more rough floating point number representation. It is used in such data structures as triangulation (MbGrid) for approximated representation of objects.

Member Function Documentation

IsSame()

bool MbFloatVector3D::IsSame ( const MbFloatVector3D &  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.
