How to check if gp_Ax1 contains gp_Pnt in OpenCASCADE

OCCUtils provides convenience functions for computing the orthogonal direction to two directions:

#include <occutils/Axis.hxx>
using namespace OCCUtils;

gp_Ax1 axis = /* ... */;
gp_Png point = /* ... */;
bool pointIsOnAxis = Axis::Contains(axis, point);

In case you can’t use *OCCUtils,*here’s the code to do it manually:

gp_Lin(axis).Contains(pnt, Precision::Confusion());
