Detailed Description

A rectangle (2 dimensions)

This SDF naively uses contours, and should be improved for serious usage.

Note

LIMIT – the 2 primary axes must be x and y

Constructor & Destructor Documentation

SDFRectangle()

madness::SDFRectangle::SDFRectangle ( const coord_2d &  length, const coord_2d &  center  )

inline

Constructor for rectangle.

Parameters

length	The lengths of the rectangle
center	The center of the rectangle

Member Function Documentation

grad_sdf()

coord_2d madness::SDFRectangle::grad_sdf ( const coord_2d &  pt ) const

inline

Computes the gradient of the SDF.

Parameters

pt	Point at which to compute the gradient

Returns

the gradient
