Working with UV mapping
The use of content viewpoints can be limiting in the following situations:
1. Video projectors surround the projection surface on which you expect
to project from all angles.
2. The projection surface surrounds the video projectors.
In both scenarios, using a single content viewpoint is not enough to cover the whole
projection surface. In those situations, you might consider using the UV mapping
technique to achieve an 'all-around' projection.
UV mapping consists of unfolding a 3D model onto a flat surface. It is similar to the
way in which a 3D article of clothing can be created from a 2D pattern, except that UV
mapping starts with the 3D article of clothing and ends with the 2D pattern from which
it was made. An unfolded version of a 3D model can then be exported as a 2D image,
so that artists can draw into it, as they would do within a content viewpoint. The main
