Creating and Editing Texture Coordinates (UVs) - An Introduction to Computer Graphics for Artists - page 168

Fig. 10.32 A sphere made from a cube retains relatively undistorted UVs from the original cube
except for the corners, which have been reprojected here
Fig. 10.33 This mapping solution would be diffi cult to paint without 3D Paint, but with 3D paint,
the results would be good quality
reduces distortion and it still has a very large area of low distortion seamless UVs.
In Fig. 10.33 some seam-crossing 3D paint has been added. On the left, the black
lines correspond to the eyelashes painted on the sphere. This solution makes sense
for objects that require high resolution textures.
