In this weeks practical, we covered projection maps. Essentially there are four different types of mapping on Maya, which includes; Automatic, Planar, Spherical and Cylindrical mapping. The different mapping types respond differently to each shape, meaning some give a better result than others.
In some cases, cylindrical mapping may not be the best option, more often than not it depend on the file you are using as the texture. As the cylinder above has a simple and consistent texture it looks fine, however, if I were to use an actual image, it would most probably be stretched out in a disorientated manor.
In this image you can see that I got three spheres and applied the same textures to them all. Fromm left to right the projection maps are; PLANAR, SPHERICAL and CYLINDRICAL. Interestingly, The planar map gave the best results. Planar mapping is usually used to texture on to a flat surface on the XYZ axis. The cylindrical map tended to stretch out ever so slightly whereas the spherical map seemed a bit of. Just like I said earlier, the spherical map would have worked fine if it was a consistent texture, however since it was an actual image of something, the right result wasn't achieved.

Naturally on a Cylinder object, cylindrical mapping would be an obvious choice as the texture would wrap around the object neatly in the circular part of the object.
