UF_FACET_add_facet_to_model (查看源代码)
定义在: uf_facet.h
概述
Adds a facet to a faceted model. The "adjacent_facet_ids" array
contains a facet id for each edge in the new facet. A value
of UF_FACET_NULL_FACET_ID means that that edge of the new
facet is not to be made adjacent to any existing facet. Note
that the adjacent facets must contain an edge corresponding
to that in the new facet, and if they do not then an error is
returned and no facet is created. This function can return the
error code UF_FACET_err_zero_facets_produced when given a
polygon with adjacent duplicate vertices.
返回
Return code:
0 = No error
not 0 = Error code, which includes
UF_FACET_err_non_manifold
UF_FACET_err_bad_adjacency
UF_FACET_err_facet_not_planar

概述
Enquires if a faceted model is convex. A model is convex if none of its
edges are concave.

UF_FACET_model_edits_done (查看源代码)
定义在: uf_facet.h
概述
Indicates that edits to the specified faceted model are now complete.
This allows the system to delete the temporary data structures which it
creates to facilitate editing. This function should be called after the
program has completed a sequence of editing operations (other than
creation and update) on a faceted model.
Note that if this routine is not called then no harm results, other than
that the program will consume more memory than is necessary.

UF_FACET_rebuild_adjacencies (查看源代码)
定义在: uf_facet.h
概述
Determines the adjacencies between the facets of a faceted body. The
routine uses the individual facet definitions and determines which
have shared edges. It is particularly useful where the faceted body has
been constructed using UF_FACET_add_facet_to_model without
specifying the adjacent facets, and may prove convenient when writing
code to import faceted models from elsewhere.

UF_FACET_update_model (查看源代码)
定义在: uf_facet.h
概述
Updates a faceted model if it was generated from a solid. This
function returns an error if the faceted model was not generated from
a solid. If NULL is specified for the faceting parameters then those
used to facet the solid previously are used.
If the model is already up to date with the same faceting parameters,
then this function performs no action. If the model is not derived from
a solid then an error is returned.

Return code:
0 = No error
not 0 = Error code, which includes
