简介：

UG二次开发 向量叉乘 UF_VEC3_cross，xyz三个向量已知2个求另外1个。

效果：

      

代码：

#include "me.hpp"

void ufusr(char* param, int* retcode, int paramLen)
{
	UF_initialize();

	//已知xy求z
	double x1[3] = { 1.0,0.0,0.0 };
	double y1[3] = { 0.0,1.0,0.0 };
	double z1[3] = { 0 };
	UF_VEC3_cross(x1, y1, z1);
	print("z1 %f,%f,%f\n", z1[0], z1[1], z1[2]);

	//已知yz求x
	double y2[3] = { 0.0,1.0,0.0 };
	double z2[3] = { 0.0,0.0,1.0 };
	double x2[3] = { 0 };
	UF_VEC3_cross(y2, z2, x2);
	print("x2 %f,%f,%f\n", x2
