| ) | [static] |
Returns "pseudo-distance" from (x,y) to ball of radius size.
- for a point inside the ball, it is proportional to the euclidean distance to the ball
- for a point outside the ball, it is proportional to the inverse of this distance (tends to zero) on the ball, the function is continuous.
