model interface definition
this is the C equivalent of a C++ class with pure virtual methods. It contains pointers to implementations for all the different geometric model operations supported by GMI. Each model points to one of these definitions so that GMI knows which code to use to interact with said model. Implementations are allowed to omit any of these pointers, in which case either that functionality is prohibited (and the program crashes upon attempted use) or a comment may describe the default behavior if the pointer is omitted. Some functionality is known to be rare, so specific APIs are in place to check whether a particular model supports those functions.
struct gmi_set*(* gmi_model_ops::adjacent)(struct gmi_model *m, struct gmi_ent *e, int dim) [read] |
implement gmi_adjacent
if omitted then gmi_adjacent returns gmi_make_set(0)
| void(* gmi_model_ops::eval)(struct gmi_model *m, struct gmi_ent *e, double const p[2], double x[3]) |
implement gmi_eval
if omitted then gmi_can_eval returns false
