Intersection between line and triangle and finding the common intersection point also?

The file_handle.cpp code provides a set of geometric utilities for 2D and 3D computations, primarily for use with OpenGL (via GLFW and GL libraries). It defines classes for points, lines, triangles, and polygons, along with methods to compute areas, check point containment, and detect intersections. Key functionalities include calculating the area of triangles and polygons in 2D and 3D, checking if a point lies within a convex polygon, and determining if a line segment intersects a triangle using an area-sum method. The code also includes OpenGL-based rendering functions to visualize these geometric primitives. This implementation is useful for applications in computer graphics, game development, and computational geometry.
