PK_ERROR_code_t       PK_OFFSET_create
(
--- received arguments ---
const PK_OFFSET_sf_t *offset_sf,    --- offset surf standard form

--- returned arguments ---
PK_OFFSET_t    *const offset        --- offset surf
)


The function creates an offset surface from the given standard form.  See
documentation for PK_OFFSET_sf_t.


Specific Errors:
    PK_ERROR_cant_offset             underlying surface cannot be offset
    PK_ERROR_distance_too_small      offset_distance is close to zero
    PK_ERROR_su_self_intersect       offset surface would be self intersecting


This function will construct an offset surface.  It accepts a PK_OFFSET_sf_t
and returns a PK_OFFSET_t.

Currently, this function supports the following underlying surface types:
PK_BSURF_t, PK_SWEPT_t and PK_SPUN_t.

This function does not support offset distances of zero length.

See, also, documentation for PK_SURF_offset.
