1. Mapping

2. Pixels or Geometry?

3. Let’s make a wall

4. Pixels?

5. or Geometry?

6. How about a brick wall?

7. Geometry?

8. or Pixels?

9. How about a window?

10. Geometry?

11. or Pixels?

12. Geometry: Pros: Fully three-dimensional
Casts shadows, reflections, etc…
Easier to position and modify
Cons:
Takes more time to calculate (render) - Slow
Complex textures hard to model

13. Pixels: Pros: Takes less time to calculate (render) – Fast
Easily represents complex textures
Cons:
Can be difficult to accurately position
Modification requires different software
Usually requires external files (texture maps)

14. Two Parts to Mapping: 1. Making a Mapped Material
Replacing a material’s color/setting with an image.
2. Assigning/Adjusting Mapping Coordinates
Tells geometry what to do with the map

15. Base Color (diffuse) – The material’s color.
Mapped Material:
Base Color (diffuse) – The material’s color.

16. Reflection (amount) – Reflective portions
Mapped Material:
Reflection (amount) – Reflective portions

17. Transparency (amount) – Transparent portions
Mapped Material:
Transparency (amount) – Transparent portions

18. Emission (amount) – Glowing portions
Mapped Material:
Emission (amount) – Glowing portions

19. Mapping Coordinates:
Assigned to geometry. Tells geometry what to do with the map:
Size/Scale of materials
Orientation (rotation)
Pattern (tiling)

20. Mapping Coordinates:
Size (Scale) – For humans or ants?

21. Mapping Coordinates: Two Types:
Real-World Scale/Size – “Best” for architectural
Tiling – “Manual” application/adjustments

22. Mapping Coordinates:
Localized axes. Labeled UVW.
