# **CSE-409 & CSE-410 `Computer-Graphics`**

This repositoy contains implementation of various algorithms in ***Computer Graphics*** both for *Theory* and *Sessional* course offered in ***Department of Computer Science and Engineering*** at ***Bangladesh University of Engineering and Technology (BUET)***.

### ***Disclaimer***

*The repository serves as an archive for the author's solutions to the course assignments and sometimes extra implementations of algorithms and techniques taught in the theory course. The solutions are **not guaranteed to be full-proof**. The author is not responsible for **any damage** caused by the use of the solutions. While it can serve as a **reference**, it is strongly discouraged to copy the solutions for **academic dishonesty**, and the author is not responsible for any consequences of such actions. The Hall of Shame ain't so forgiving!*

Implementations of theoretical algorithms include the following:
   - **Cohen Sutherland** Line Clipping Algorithm
   - **Cyrus Beck** Line Clipping Algorithm
   - **Sutherland Hodgeman** Polygon Clipping Algorithm
   - **Bresenham**'s Line Drawing Algorithm
   - **Unweighted Anti-Aliasing**
   - **Weighted Anti-Aliasing**
   - **Koch Curve** Fractal
   - **Koch Snowflake** Fractal
   - **Dragon Curve** Fractal

And for the sessional, we have 
- **Open GL** basics
- **Raster based Graphics Pipeline** ({Model,View,Projection} Transformation + Z-Buffer Hidden Surface Removal Algorithm
- **Ray Tracing**
