Box Projection
The box projection is the simplest projection to use and the one that is the most multi-purpose. The gizmo takes the form of a box that surrounds the surface. Each face of the box corresponds to a planar projection.
You can use this projection operator in most situations, since the resulting mapping grid is sparingly deformed, irrespective of the geometry of the surface.
On the other hand, the material can be cut into several pieces to cover the surface.
This mapping operator is ideal when you use uniform materials bearing no pattern.
