Detailed Description

Function/Subroutine Documentation

copy_shape_polygon()

subroutine mod_shape_polygon::copy_shape_polygon	(	class(t_shape_polygon), intent(in)	shape,
		class(t_shape), allocatable	copy
	)

Parameters

[in]	shape	polygon shape
[out]	copy	copied polygon shape

initialize_shape_polygon()

subroutine mod_shape_polygon::initialize_shape_polygon

(

class(t_shape_polygon), intent(inout)

shape

)

Parameters

[in,out]

shape

polygon shape

shape_polygon_get_distance()

pure subroutine mod_shape_polygon::shape_polygon_get_distance	(	class(t_shape_polygon), intent(in)	shape,
		double precision, dimension(3), intent(in)	point,
		double precision, intent(out)	distance,
		double precision, dimension(3), intent(out)	direction
	)

If the point lies inside the polygon, the distance is negative and the direction points to the closest point on the polygon. If the point lies outiside the polygon, the distance is positive and the direction points in the opposite direction to the closest point on the polygon.

Parameters

[in]	shape	polygon shape
[in]	point	any point
[out]	distance	signed closest distance from the point to the polygon
[out]	direction	signed direction from the point to the closest point on the polygon
