Detailed Description

A cone skeletal element.

Constructor & Destructor Documentation

◆ TreeCone()

TreeCone::TreeCone ( const Vector a,
const Vector b,
const double &  ra,
const double &  rb,
BlendCompact blend 
)

Create a cone.

This constructor ensures that the vertex with the small radius is always the same so as to improve the point classification tests involved in the TreeCone::Normal() function.

Parameters
a,bEnd vertices of the cone.
ra,rbRadii at the end vertices of the code.
blendFalloff function.

Member Function Documentation

◆ Intensity()

double TreeCone::Intensity ( const Vector p) const
virtual

Computes the squared Euclidean distance to the skeleton.

This virtual member function calls TreeNormal::Normal() function. It is inefficient and should be reimplemented whenever possible.

Parameters
pPoint.

Reimplemented from TreeNormal.

◆ Rotate()

TreeNode * TreeCone::Rotate ( const Matrix r)
virtual

Rotates a cone element.

Instead of inserting a rotation node in the tree, simply updates the vertices of the cone as well as its internal parameters.

Parameters
rRotation matrix.

Reimplemented from TreeNode.

◆ Translate()

TreeNode * TreeCone::Translate ( const Vector t)
virtual

Translate the primitive.

Parameters
tTranslation vector.

Reimplemented from TreeNode.
