UF_SF_find_minimum_distance

ccx8301

UF_SF_find_minimum_distance这个函数怎么用啊？有没有例子。
( \* p1 e, R5 {& X( s! G% a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：
* d  Z* [) x5 t2 m  int ret;
1 x7 h* ]9 J: }9 f  tag_t body_tag_1;
% Q  G$ r' `/ i6 [  tag_t body_tag_2;
  tag_t cyl_tag;
  char *edge_lens[3]={"10","10","10"};
5 y: g+ [+ R' j2 b2 G1 W   ret=UF_MODL_create_block1(UF_UNITE ,origin,edge_lens,&cyl_tag);
  tag_t part_1;
  double origin1[3]={0,0,20};
  char h1[256]="20";
3 z; Y  O- G! u9 N0 `  char d1[256]="40";

  U% ^$ n- C* ~. H& n: H  ret=UF_MODL_create_block1(UF_UNITE ,origin1,edge_lens,&part_1);

UF_MODL_ask_feat_body(part_1,&body_tag_2);

  data.value.real=3.14;
  double min_dist;
   UF_SF_find_minimum_distance(body_tag_1,body_tag_2,&min_dist,point,point1);
  data.value.real=min_dist;

谢谢！！！！
