Project Introduction
Computer Graphics is one of the most exciting areas of programming because it allows us to create visual worlds using code. In this project, we developed a fully animated university campus scene using OpenGL with GLUT in C++. The project demonstrates how basic graphics primitives such as polygons, circles, and lines can be combined to create an interactive animated environment.
Project Overview
In this project, we created a fully animated university campus using OpenGL with GLUT in C++.
The scene includes buildings, football ground, moving vehicles, animated students, birds, rain effects, day/night mode, and several interactive graphics features.
Features Included
The campus simulation includes:
- A large university building
- Football Ground with Goal Posts
- Animated Students
- Moving Cars and Buses
- Flying Airplane
- Rain Effect
- Day and Night Mode
- Animated White Flag
- Trees and park area
- University Gate
- Fountain Animation
- Birds and Clouds
- User interaction using keyboard controls
This project is ideal for beginners who want to learn:
- OpenGL fundamentals
- 2D graphics drawing
- Animation techniques
- Event handling
- User interaction
- Real-time rendering
Technologies Used
Understanding the Graphics Concepts
1. Drawing Shapes
OpenGL uses vertices to create graphics objects. Rectangles, polygons, and circles are combined to create buildings, roads, vehicles, and trees.
glBegin(GL_QUADS);
glVertex2f(x,y);
glVertex2f(x+80,y);
glVertex2f(x+80,y+25);
glVertex2f(x,y+25);2. Animation
Animation is achieved by updating object positions continuously using timer functions.
planeMove += 1.5f;
carMove += 2.0f;
glutTimerFunc(16, update, 0);
3. Interactive Controls
Keyboard controls allow users to interact with the scene.
case 'n':
nightMode = !nightMode;
break;
Keyboard Controls
| Key | Action |
|---|---|
| N | Toggle Night Mode |
| R | Toggle Rain |
| B | Toggle Bus |
| C | Toggle Cars |
| P | Toggle Plane |
| ESC | Exit Program |
