UF_SF_find_minimum_distance

ccx8301

UF_SF_find_minimum_distance这个函数怎么用啊？有没有例子。
我创建了两个正方体，来求两个实体的最小距离，好像不行，且我已经把，feature转换成body的tag了。代码如下：
. I' f0 N, o5 j% ?$ N" K6 M/ H  int ret;
  tag_t body_tag_1;
  tag_t body_tag_2;
  tag_t cyl_tag;
( @6 R! p/ G6 G) L  Q+ Z% x2 a# p  char *edge_lens[3]={"10","10","10"};
% ^! `# M& r8 `' c0 V! i/ F   ret=UF_MODL_create_block1(UF_UNITE ,origin,edge_lens,&cyl_tag);
( s8 F: D* D, i: t' @, K! N  tag_t part_1;
8 K; U- [7 I" U. Q  double origin1[3]={0,0,20};
  char h1[256]="20";
  char d1[256]="40";

0 F$ W+ h% v, a, @$ r' V( Q  ret=UF_MODL_create_block1(UF_UNITE ,origin1,edge_lens,&part_1);
- |; V7 _8 u' {3 z3 }# eUF_MODL_ask_feat_body(cyl_tag,&body_tag_1);
UF_MODL_ask_feat_body(part_1,&body_tag_2);
5 d' a1 r' k2 `  H% Y  double point[3],point1[3];
8 N/ k' H0 o" D: n! R+ l  data.value.real=3.14;
0 o- @- a9 q3 q$ ^. r' U- K  r  double min_dist;
/ g9 T5 _8 _* v3 ]1 S+ p( S   UF_SF_find_minimum_distance(body_tag_1,body_tag_2,&min_dist,point,point1);
  data.value.real=min_dist;
6 o  w$ U: b& T4 v   UF_STYLER_set_value(dialog_id,&data);
' Q+ ?- c! V2 }4 _0 I谢谢！！！！
