急求:三维点的法向量的求法?????
 
[SIZE="4"]请教大家:
[SIZE="4"][/SIZE]已知空间三维点的坐标如
[ 36.0000 32.0000 198.2768
25.0000 33.0000 198.1585
26.0000 33.0000 197.8793
27.0000 33.0000 197.8186
28.0000 33.0000 197.7930
29.0000 33.0000 197.7744
30.0000 33.0000 197.7674
31.0000 33.0000 197.7674
32.0000 33.0000 197.7755
33.0000 33.0000 197.7942
34.0000 33.0000 197.8198
35.0000 33.0000 197.8805]

怎么求每个点的法向量呀???并把每个点的法向量画出来???? [/SIZE]
