Why Texture Map?
•So far
we have done flat shading and Gouraud shading
–Not
good to represent everything in real world
•What
are some of our other options?
–Represent
everything with tiny polygons
•Geometry
would get complicated very quickly
–Apply
textures across the polygons
•This
allows for less geometry but the image looks almost as good
