[Bf-committers] Angle Calculation Code

[Ton Roosendaal]

Hi,

That cannot be done simply, because Blender Mesh allows any level of  
connectivity between edges. Constructing lists of  
edges-connected-to-edges will be time consuming, especially for use in  
redrawing code.

Using a face isn't too bad, also because you know all angles make up to  
360 degrees, so you can calculate the missing one easily. :)
