Unfold3D

Unfold3D was one of the first automatic unwrapper on the market, and is still the best product in its field.

Through a simple "cut & click" workflow, it produces in seconds hig quality UV mappings, usable right out of the box. It uses a top of the art algorithm to minimize polygon distorsion, which produces results far better than any handmade UVs. The time to produce UV mappings is taken down to minutes. Texturers can now forget about the tedious job of creating UVs, and concentrate on the texture creation part.
In the workflow of 3D modeling, an important part is dedicated to texturing the 3D objects, that is: to map a 2D image (the image of a skin, of a tissute, of a rock...) on the surface of a 3D model (a man or animal, a piece of clothing, a landscape element...).
The texture, the image which is to be painted on the object, is generally a 2D image obtained from a photo or an external 2D processing software.
But before you can map this texture on a 3D model, you need to know what part of the image should be mapped on each polygon of the model. There are several names, all referencing this correspondance between the faces of the object in the 3D world and the texture's 2D plane: texture coordinates, UV coordinates or UV mapping.
