PK_SURF_self_ints_t

struct PK_SURF_self_ints_s
    {
    int                 n_self_int; --- number of self-intersections
    PK_SURF_self_int_t *self_int;   --- details of self-intersections
    };

typedef struct PK_SURF_self_ints_s PK_SURF_self_ints_t;



A structure packaging details of self-intersections on a surface.

Used in:

PK_SURF_find_self_int
PK_SURF_fix_self_int
PK_SURF_self_ints_f

The structure has the following fields :

'n_self_int'        The number of self-intersections on the surface.

'self_int'          An array of length 'n_self_int', holding information on
                    each self-intersection. Each self-intersection corresponds
                    to a physical region in three-space, and consists of one or
                    more parametric regions of the surface. For example, for a
                    surface which has two parametric regions "A" and "B"
                    occupying the same physical space, and two more parametric
                    regions "C" and "D" occupying another space, then the
                    function would return an array of length two, with one
                    entry storing the parametric regions "A" and "B", and the
                    other entry storing the parametric regions "C" and "D".

The function PK_SURF_self_ints_f may be used to free associated memory.
