UF_FORGEO_ask_surface_params_f_t (view source)
Defined in: uf_forgeo.h
Overview
This function is used to define the valid parameter range for the surface.
A place is saved to handle periodic surfaces but this is not yet supported.
void UF_FORGEO_ask_surface_params_f_t
(
int int_array [ ] ,
double double_array [ ] ,
double fg_data [ ] ,
double * uvbox,
int period [ 2 ]
)
| int | int_array [ ] | Input | - array of integers for surface |
| double | double_array [ ] | Input | - array of doubles for surface |
| double | fg_data [ ] | Input | - FG data array |
| double * | uvbox | Output | - uv parameter box for surface |
| int | period [ 2 ] | Output | - u and v periodicity flags for surface
[0] = u, [1] = v

UF_FORGEO_create_surface_f_t (view source)
Defined in: uf_forgeo.h
Overview
This function will be called when a foreign surface is created. This will
occur either during new surface creations or during load of existing models.
NX will ask you to prepare to process this surface. You need to prepare to
evaluate this surface and return whether or not evaluation is possible. The
fg_data array can be used any way you wish. You may want to store
information to make the evaluation faster or you could store the address of
the evaluation function for this surface if multiple surface types are
supported and you want to remove a switch between surface types during each
evaluation.

(
char * char_data,
int num_ints,
int * int_array,
int num_doubles,
double * double_array,
int num_data,
double * fg_data
)
| char * | char_data | Input | - character string data for surface |
| int | num_ints | Input | - number of integers defining surface |
| int * | int_array | Input | num_ints - array of integers for surface |
| int | num_doubles | Input | - number of doubles defining surface |
| double * | double_array | Input | num_doubles - array of doubles for surface |
| int | num_data | Input | - FG data length |
| double * | fg_data | Input / Output | num_data - FG data array

Defined in: uf_forgeo.h
Overview
This function will be called when evaluation of the foreign surface is
needed. You need to support up to second derivatives.
