Detailed Description

Unary planar nodes.

Constructor & Destructor Documentation

SDFUnary2::SDFUnary2 ( SDFNode2 * n )

explicit

Create an unary planar node.

Default Lipschitz constant and box are computed from the sub-tree.

Parameters

n	The sub-tree.

double SDFUnary2::K ( ) const

virtual

Return the Lipschitz constant of the node.

By default, nodes are considered as signed Euclidean distance functions, and the Lipschitz consistant is λ=1.

Reimplemented from SDFNode2.

int SDFUnary2::Nodes ( ) const

virtual

Compute the number of nodes in the sub-tree.

Reimplemented from SDFNode2.

double SDFUnary2::Signed ( const Vector2 & p ) const

virtual

Compute the signed distance.

Parameters

p Point.

Reimplemented from SDFNode2.
