Detailed Description

Euclidean signed distance field for a convex polygon.

Constructor & Destructor Documentation

SDFConvex2() [1/2]

SDFConvex2::SDFConvex2 ( const Convex2 &  c )

explicit

Create a convex primitive.

Parameters

c

Convex2

SDFConvex2() [2/2]

SDFConvex2::SDFConvex2 ( const QVector< Vector2 > &  pts )

explicit

Create a convex primitive from a set of points.

Parameters

pts

points

Member Function Documentation

Copy()

SDFNode2 * SDFConvex2::Copy ( ) const

virtual

Implements SDFNode2.

Memory()

int SDFConvex2::Memory ( ) const

virtual

Return the size of a sub-tree.

Reimplemented from SDFNode2.

Signed()

double SDFConvex2::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 Convex2::R(const Vector2&).

Reimplemented from SDFEuclidean2.
