Hi All,

Here is the problem definition:

Suppose you have a Quad face with a different normal for each vertex. Now we cut it because of a boolean operation. How shall we compute the new vertices normals? We are already using the face normal but the result is very unpleasant.

Is there a way to compute the contribuition of each original normal at the new vertex position and get a good guess?

The data available is of course the vertices position in 3D, the 4 original normal vectors and the face normal.

Thanks in advance,

Alberto
