Member Function Documentation

◆ Memory()

int SDFQuadricCurveSet2::Memory ( ) const
virtual

Return the size of a sub-tree.

Reimplemented from SDFNode2.

Reimplemented in SDFQuadricCurveSetThick2.

◆ Signed()

double SDFQuadricCurveSet2::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
pPoint.

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

Reimplemented from SDFEuclidean2.

Reimplemented in SDFQuadricCurveSetThick2.
