使用uf5374()

源码：

double dP1\[3\] = { 0.0,0.0,0.0 };  
double dP2\[3\] = { 0.0,1.0,0.0 };  
double dP3\[3\] = { 0.0,0.0,1.0 };  
tag\_t tagPlane;  
uf5374(dP1, dP2, dP3, &tagPlane);

使用UF_MODL_create_plane()

double dP1\[3\] = { 0.0,0.0,0.0 };  
double dDir\[3\] = { 1.0,0.0,0.0 };  
tag\_t tagPlane;  
UF\_MODL\_create\_plane(dP1, dDir, &tagPlane);

效果：
