Member Function Documentation

Memory()

int SDFCircle2::Memory ( ) const

virtual

Return the size of a sub-tree.

Reimplemented from SDFNode2.

Signed()

double SDFCircle2::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.

Reimplemented from SDFEuclidean2.
