Detailed Description

Base class for all volumetric geometries Note that checkContain and findClosest point are basic function, They should not call other functions in shape.

Member Function Documentation

findNormalDirection()

Vecd SPH::Shape::findNormalDirection

(

const Vecd &

input_pnt

)

Normal direction point toward outside of the complex shape.

findSignedDistance()

Real SPH::Shape::findSignedDistance

(

const Vecd &

input_pnt

)

Signed distance is negative for point within the complex shape.
