Visualizing Point Position Relative to a Line using OpenGL

Overview: This interactive visualization tool demonstrates how to determine whether a 2D point lies above, below, or on a line using the signed area (cross product) method. Color coding enhances understanding: 🔴 Red: Point is above the line 🔵 Blue: Point is below the line 🟢 Green: Point lies on the line Technology Used: C++ with OpenGL and GLFW 2D orthographic projection for geometric clarity Educational for students, developers, and anyone learning geometry or graphics
