Detailed Description

Three-dimensional point.

MbFloatPoint3D class is used for a three-dimensional point representation as well as a similar MbCartPoint3D class which differs by higher precision of representation. MbFloatPoint3D has data structure consisting of a triple of a single precision floating point numbers (float). Used for polygonal representation of a three-dimensional geometric objects in such data structures as polygon (MbPolygon3D) or triangulation (MbGrid).

Constructor & Destructor Documentation

◆ MbFloatPoint3D()

MbFloatPoint3D::MbFloatPoint3D ( )
inline

Default constructor.

Constructs a point with coordinates (0.0, 0.0, 0.0).

Member Function Documentation

◆ Set()

MbFloatPoint3D & MbFloatPoint3D::Set ( const MbFloatPoint3D v1,
const MbFloatVector3D v2,
float  t2 
)
inline

Equate coordinates to sum of point coordinates and vector coordinates.

Equate coordinates to sum of v1 point coordinates and v2 vector coordinates multiplied by t2.

Parameters
[in]v1- The initial point.
[in]v2- The initial vector.
[in]t2- Factor the coordinates of the initial vector v2 are multiplied by.

◆ IsSame()

bool MbFloatPoint3D::IsSame ( const MbFloatPoint3D 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.
