S2Projections.UvTransform (S2 Geometry Library for Java 2.0.0 API)

java.lang.Object
- com.google.common.geometry.S2Projections.UvTransform

Enclosing class:

S2Projections
```
public abstract static class S2Projections.UvTransform
extends Object
```
A transform from 3D cartesian coordinates to the 2D coordinates of a face. For (x, y, z) coordinates within the face, the resulting UV coordinates should each lie in the inclusive range [-1,1], with the center of the face along that axis at 0.
