Constructor & Destructor Documentation

SDFCubicCurveSet2()

SDFCubicCurveSet2::SDFCubicCurveSet2 ( const CubicCurve2Set &  c )

explicit

Create a rounded cubic curve primitive.

Parameters

c	Quadric curve set.

Member Function Documentation

Memory()

int SDFCubicCurveSet2::Memory ( ) const

virtual

Return the size of a sub-tree.

Reimplemented from SDFNode2.

Signed()

double SDFCubicCurveSet2::Signed ( const Vector2 &  p ) const

virtual

Compute the signed Euclidean distance function.

By default compute the signed distance to the bounding box of the primitive.

Parameters

p

Point.

Internally, call CubicCurve::R(const Vector&) and take the square root.

Reimplemented from SDFEuclidean2.
