brick - internal angles.

[zampa]

Hi.

I want to calculate the minimal internal angle of a 3D-brick ,resulting from a trilinear interpolation (

http://paulbourke.net/miscellaneous/interpolation/),

with the minimal computacional cost.

Of course, I can take for each node, a pair of vectors and calculate the angle between them (for example, using cosinus).

But is there any faster way to get the minimal interior angle.

My input are 8 vertices in 3D Space.

Thanks.

that's the best way imo. use numpy for better results, as calculating in py for every element in computationally intensive.
