1. The Graphic PipeLine

2. Four Stages Vertex Processing Vertex → Primitives Transformations
Rasterization
Primitives → Fragments
Fragment Processing
Texture + Lighting
Output Merging
Hidden Surface Removal + Blending

3. 1 – Vertex Processing

4. What’s a vertex ? Position: (x, y, z) Color: (r, g, b, a)
Vertex normal: lighting
Texture Vertex

5. What’s a primitive ? Points Line Segments Lines, Line Strip, Line Loop
Closed Polygons
Triangles, Triangle Strip, Triangle Fan
Quads, Quad Strips

6. Transformed Geometry

7. What is Model Transform ?

8. What is View Transform ?

9. What is Projection Transform ?

10. What is Viewport Transformation ?

11. 2 - Rasterization

12. What’s a fragment ?
2D pixels AND
Color
Vertex Normal
Texture Vertex

13. 3 – Fragment Processing

14. Textures Wrapping Repeat Filtering
Minify or Magnify to match resolution

15. Filtering

16. Lighting: Phong Model
Diffuse
Specular
Ambient
Emissive

17. Diffusion & Reflection

18. 4 – Output Merging

19. Hidden Surface Removal
Z - buffering

20. Alpha Blending

21. Blending Modes
