To store and treat a figure (or shape) information.

This class is essentially useful to construct data for mesh generators and for distance calculations.

◆ dLine()

real_t dLine ( const Point< real_t > &  p,
const Point< real_t > &  a,
const Point< real_t > &  b 
) const

Compute signed distance from a line.

Parameters
[in]pPoint for which distance is computed
[in]aFirst vertex of line
[in]bSecond vertex of line
Returns
Signed distance

◆ getSignedDistance() [1/2]

void getSignedDistance ( const Grid g,
Vect< real_t > &  d 
) const

Calculate signed distance to current figure with respect to grid points.

Parameters
[in]gGrid instance
[in]dVect instance containing calculated distance from each grid index to Figure
Remarks
Vector d doesn't need to be sized before invoking this function

◆ getSignedDistance() [2/2]

virtual real_t getSignedDistance ( const Point< real_t > &  p) const
virtual

Return signed distance from a given point to current figure.

Parameters
[in]pPoint instance from which distance is computed

Reimplemented in Rectangle, Rectangle, Brick, Brick, Circle, Circle, Sphere, Sphere, Ellipse, Ellipse, Triangle, Triangle, Polygon, and Polygon.
