如何在 OpenCASCADE 中检查 gp_Ax1 是否包含 gp_Pnt
OCCUtils 提供了计算两个方向的正交方向的便捷函数：
occutils_example.cpp
#include <occutils/Axis.hxx>
using namespace OCCUtils;
gp_Ax1 axis = /* ... */;
gp_Png point = /* ... */;
bool pointIsOnAxis = Axis::Contains(axis, point);如果你不能使用 OCCUtils，这里是手动执行的代码：
manual_check.cpp
gp_Lin(axis).Contains(pnt, Precision::Confusion());Check out similar posts by category:
