A graphical simulation of a simple pendulum using OpenGL and GLUT with smooth rhythmic animation.
This project demonstrates the simulation of a Simple Pendulum using Computer Graphics concepts in OpenGL (GLUT).
The pendulum swings continuously between two extreme positions (A and B), representing rhythmic oscillatory motion. The project was developed as part of a Computer Graphics Lab Assignment.
✅ Rhythmic pendulum animation
✅ Fixed suspension point
✅ Circular pendulum bob
✅ Real-time motion using GLUT Timer
✅ Clean OpenGL rendering
✅ Lightweight and efficient implementation

└── position_B.pngThe pendulum motion is created using:
- Trigonometric functions (
sin,cos) - Angular motion updates
- GLUT Timer Function
- OpenGL primitive drawing
The bob position is calculated dynamically using:
bx = cx + length * sin(angle)
by = cy - length * cos(angle)The angle continuously changes to create oscillatory movement.
