Part VII: Advanced Materials
Using Pelt Mapping
Consider mapping a complex mesh like the human head. Using traditional mapping methods, you would
divide the head into sections based on planar projections like those in Figure 32.15. The UVs for this head
include planar views of the front and back of the head. These provide good UV coordinates for those fea-
tures that are straight on with the projection, but the ears and the sides of the nose are all wrong using this
method. You could divide the mesh into more projections, including one for each side of the head and for
under the chin, but then you need to deal with matching the seams between the different parts, which is a
tough challenge.

Planar mapping isn’t a good solution for a complex head mesh.
