Texture Mapping
- Problem: Need small details, but cannot afford more polygons
- Solution: Take a picture and paste it onto a model like wall paper or gift wrapping
- Algorithm:
- Map a u,v coordinate pair onto each model vertex
- Then, interpolate like we have with depth, color and normals
- Hardware is available for this process, so it's fast
- Problems with interpolated approximations can be very severe
Issues
- Variety of ways to map
- Perspective distortion
- Aliasing
- Level of Detail (MipMaps)
