大家好,今天讲关于旋转UFUN函数使用。

UF_MODL_create_revolved (view source)

uf_list_p_t obj_id_list Input List of objects or one section builder object tag
but not both, to be revolved
char * limit [ 2 ] Input Limits of revolution. The declaration should be
limit[2], where limit[0] = start angle and limit[1] =
end angle. Angles are in degrees.
double point [ 3 ] Input Point
double direction [ 3 ] Input Revolution axis.
UF_FEATURE_SIGN sign Input The sign of the operation to be performed.
UF_NULLSIGN = create new target solid
UF_POSITIVE = add to target solid
UF_NEGATIVE = subtract from target solid
UF_UNSIGNED = intersect with target solid
uf_list_p_t * feature_list Output to UF_*free* List of feature identifiers created. This
list must be freed by calling UF_MODL_delete_list.

这个是旧版的旋转函数,里面虽然有可以使用布尔减,但是没有传入目标体的Tag值。所以他是默认减去一个体,这样会造成我们使用灵活性方面的困难,而下面这个新版的函数就没有这方面的问题了。

UF_MODL_create_revolved1 (view source)

uf_list_p_t obj_id_list Input List of objects or one section builder object tag
but not both, to be revolved
char * limit [ 2 ] Input Limits of revolution. The declaration should be
limit[2], where limit[0] = start angle and limit[1] =
end angle. Angles are in degrees.
double point [ 3 ] Input Point
double direction [ 3 ] Input Revolution axis.
UF_FEATURE_SIGN sign Input The sign of the operation to be performed.
UF_NULLSIGN = create new target solid
UF_POSITIVE = add to target solid
UF_NEGATIVE = subtract from target solid
UF_UNSIGNED = intersect with target solid
tag_t target_body Input Boolean target
uf_list_p_t * feature_list Output to UF_*free* List of feature identifiers created. This
list must be freed by calling UF_MODL_delete_list.

倒数第二个参数就为目标体的tag值。

今天要讲的就是这么多,我们下篇文章再见。
