UF_FORGEO_ask_surface_params_f_t (查看源代码)

定义在: uf_forgeo.h

概述

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 (整数型)	int_array [ ]	Input（输入）	- array of integers for surface
double (实数型)	double_array [ ]	Input（输入）	- array of doubles for surface
double (实数型)	fg_data [ ]	Input（输入）	- FG data array
double * (实数型指针)	uvbox	Output（输出）	- uv parameter box for surface
int (整数型)	period [ 2 ]	Output（输出）	- u and v periodicity flags for surface [0] = u, [1] = v UF_MODL_NON_PERIODIC or UF_MODL_PERIODIC (not yet supported)

UF_FORGEO_create_surface_f_t (查看源代码)

定义在: uf_forgeo.h

概述

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.

定义在: uf_forgeo.h

概述

This function will be called when evaluation of the foreign surface is
needed. You need to support up to second derivatives.
