Detailed Description

This class defines a discretization of a sphere from the tesselation of a basic platon solid (icosahedron).

The points are all located on a unit radius sphere.

Constructor & Destructor Documentation

RSphereTesselation::RSphereTesselation ( )

Default constructor (no points).

RSphereTesselation::~RSphereTesselation ( )

virtual

Destructor.

Member Function Documentation

RSphereTesselation::GObject ( RSphereTesselation )

private

Macro from GCpp library that defines the following functions:

ClassName(): return the real class name of the object
StaticClassName(): return the used class name of the object (that may be a base class of the real object).
IsInstanceOf<T>(): return true if the current object is an instance of the template class name argument
Clone(): return an allocated copy of the object.

void RSphereTesselation::InitData ( )

virtual

Function sets the initial points and segments from an icosahedron.

Implements RSolidTesselation.

int RSphereTesselation::SubDivide ( int n )

virtual

Function subdividing the points. The function returns the new number of points, or -1 in case of failure.

Parameters

n	number of division iterations

References SubDivide().

Referenced by RHoughTransform3D::SetTesselation().

int RSphereTesselation::SubDivide ( )

virtual

Function subdividing the points.

For now, the algorithm uses the brute force to recreate the segments: it looks for points below a given distance. All points combitations are considered, which is not efficient. A better one should be searched for.

Implements RSolidTesselation.
