OCCUtils provides convenience functions for getting the midpoint (also called the center) between 2 or more points:
#include <occutils/Point.hxx> using namespace OCCUtils; gp_Pnt p1 = /* ... */; gp_Pnt p2 = /* ... */; gp_Pnt midpointOfP1AndP2 = Point::Midpoint({p1, p2});
You can also call Point::Midpoint()
with a std::vector<gp_Pnt>
.
In case you can’t use OCCUtils, here’s the code to do it manually:
double x = 0.0, y = 0.0, z = 0.0; for (const gp_Pnt &pnt : points) { x += pnt.X(); y += pnt.Y(); z += pnt.Z(); } size_t size = points.size(); gp_Pnt midpoint(x / size, y / size, z / size);
