UV Mapping Vs. Projection
In Modo, there are two ways of “mapping” an image onto a piece of geometry: UV mapping, and projection. Think of UV mapping as putting a bunch of pins into a piece of stretchy cloth on the surface of your object, so that no matter how the object moves or changes, the cloth goes along for the ride.
Think of projection as a film projector, throwing your image onto the object from across the room. The film projection analogy is incomplete, because there are actually several kinds of projection (solid, planar, cubic, spherical, cylindrical, etc), but the point is that you’ve got a ‘projector’–called a ‘locator’ in modo–that throws your image onto the object.
Here we’ll look at a few of the basics of these two mapping solutions. Second video after the jump:
