Basic introduction to computer graphics and graphics pipeline.

1. Graphics process and Types of Transformations Introduction toComputer Graphics Prepared By: Mohammad Abdelilah – MostafaKhairy – TarekKhatab

2. The Graphics Process

3. Step 1 – The Game is Launched

4. Step 2 – The Data Loads into RAM

5. Step 3 – The CPU Processes the Data

6. Step 4 – The Graphics Driver Translates the Data

7. Step 5 – The Graphics Port Transfers the Data

8. Step 6 – The VRAM Stores the Data

9. Step 7 – The GPU Core Processes the Data

10. The Graphics Pipeline

11. Transformation

12. 1- Translation Translation Matrix

13. 1- Translation Example

14. 2- Scaling & Reflection Scaling & Reflection Matrix If Sx=Sy=Sz Uniform Scaling (>1: Expansion, <1 : Compression) If they’re not equal  Non-Uniform Scaling If Sx or Sy or Szhave negative values  Reflection

15. 2- Scaling & Reflection Example 1: Scaling

16. 2- Scaling & Reflection Example 2: Reflection

17. 3- Shear Shear Matrix The resulting coordinates depend Linearly on the original ones.

18. 3- Shear Example

19. 4- Rotation Rotation Matrices

20. 4- Rotation Example
