UV_FaceBranch Struct Reference

Public Attributes
BMFace *	efa
float	branch

Detailed Description

Store a face and it's current branch on the generalized atan2 function.

In complex analysis, we can generalize the arctangent function into a multi-valued function that is "almost everywhere continuous" in the complex plane.

The downside is that we need to keep track of which "branch" of the multi-valued function we are currently on.

Note

Even though atan2(a+bi, c+di) is now (multiply) defined for all complex inputs, we will only evaluate it with b==0 and d==0.
