菜鸟跪求指点SET_DEFORMING_THREAD_FLAG(THREAD_T0(tf))是什么意思

buaa4gaowei0

看帮助里的例子用到这条语句SET_DEFORMING_THREAD_FLAG(THREAD_T0(tf));
这个是宏吗，它的用法是什么，最关键的是在哪里找到它的用法啊？我在帮助里怎么找不到
求教各位大侠都是怎么学习动网格的啊！

DEFINE ...

There are two macros, THREAD_T0(t) and THREAD_T1(t), that can be used to identify cell threads that are adjacent to a given face f in a face thread t. THREAD_T0 expands to a function that returns the cell thread of a given face';s adjacent cell c0, and THREAD_T1 returns the cell thread for c1 (if it exists).
