PK_outline_identity_t

typedef int PK_outline_identity_t;


This datatype indicates the identity of a curve produced by
PK_BODY_make_curves_outline, PK_BODY_make_spun_outline and
PK_BODY_make_persp_outline operations. It has the values:

    PK_outline_identity_2d_c    Outline curve from a solid or non-edge-on
                                sheet component of an input body. If projected,
                                the curve defines the boundary of an area with
                                other outline curves.

    PK_outline_identity_1d_c    Outline curve from a wire or edge-on sheet
                                component of an input body.

    PK_outline_identity_axis_c  Line created along spun axis in a
                                PK_BODY_make_spun_outline operation.

    PK_outline_identity_bound_c Curve created along the boundary of a viewing
                                range in a PK_BODY_make_persp_outline
                                operation.
