Is there any way to find Ray - Shape intersection point?

Hi! I wanna made shape selection tool, so, is here any way to find ray to shape intersection point or at least make intersection test (true / false) ?

You may use IntCurvesFace_ShapeIntersector for precise intersection. For visualization, it is often enough to intersect a ray with triangulation. This is how OCCT selection works (based on BVH decomposition of an object).
