判断点在圆柱体范围内的C++代码
时间: 2023-05-18 11:07:00 浏览: 105
以下是一个简单的判断点是否在圆柱体范围内的 C 代码:
```c
#include <stdio.h>
#include <math.h>
int main() {
double x, y, z, r, h;
printf("请输入圆柱体的底面圆心坐标(x, y, z):");
scanf("%lf %lf %lf", &x, &y, &z);
printf("请输入圆柱体的底面圆半径和高(r, h):");
scanf("%lf %lf", &r, &h);
printf("请输入要判断的点的坐标(x, y, z):");
scanf("%lf %lf %lf", &x, &y, &z);
double d = sqrt(pow(x - x0, 2) + pow(y - y0, 2));
if (d <= r && z >= z0 && z <= z0 + h) {
printf("点在圆柱体内\n");
} else {
printf("点不在圆柱体内\n");
}
return 0;
}
```
其中,x0, y0, z0 分别为圆柱体底面圆心的坐标。

计算点到圆柱体轴线距离的C++代码
以下是计算点到圆柱体轴线距离的C代码:
#include <stdio.h>
#include <math.h>
double distance(double x1, double y1, double z1, double x2, double y2, double z2, double r) {
double dx = x2 - x1;
double dy = y2 - y1;
double dz = z2 - z1;
double d = sqrt(dx*dx + dy*dy + dz*dz);
double dist = sqrt(d*d - r*r);
return dist;
}
int main() {
double x1 = 0, y1 = 0, z1 = 0; // 圆柱体轴线上的一点坐标
double x2 = 1, y2 = 2, z2 = 3; // 外部点的坐标
double r = 2; // 圆柱体的半径
double dist = distance(x1, y1, z1, x2, y2, z2, r);
printf("点到圆柱体轴线的距离为:%lf\n", dist);
return 0;
}

```
以上代码中,IsInnerCircle() 函数用于判断一个点是否在圆柱面的内圆上,其中 center、normal 和 point 都是 NXOpen 中的 CartesianPoint 和 Vector3d 类型,分别表示圆柱面的圆心坐标、法向量和测试点的坐标。如果该函数返回 true,则表示测试点在圆柱面的内圆上;否则,表示测试点在圆柱面的外圆上。
