Summary  
Techniques for automatically computing 2D parameterizations of surface meshes by projecting geometry from different viewpoints and optimizing layout to minimize distortion. It covers projection-based mapping and bounding-scaling algorithms for efficient coordinate generation.

General domain of usage  
3D modeling

Blender offers various automatic UV unwrapping options to save time.

### Smart UV Project

Blender automatically determines the optimal way to project textures onto the mesh without requiring manual seam placement.

It has minimal texture stretching when applied at the default settings.


### Project from View

This method unwraps UVs based on the current viewport perspective.  The entire object is flattened according to how it appears from the user’s perspective in the 3D viewport.

### Project from View [Bounds]

This method scales UVs to maximize their size without exceeding the boundaries of the image texture.
