calculate dip angles greater than 90°

[leo]

Hi,
I have a point cloud of a natural cliff. First I calculated normals oriented using Minimum Spanning Tree, then I converted them to a Dip/Dip direction scalar field. The resulting scalar field goes from 0 to 90°. In my case I would like to create a scalar field which preserves the negative-greater than 90 dip information, is there a way to obtain it? Playing with the normal menu I created normals oriented with -Z. The resulting representation of the point cloud is blacked everywhere except in the surfaces where there is a negative dip angle (or greater than 90°, depends).
Thank you

The 'geologic' definition of the dip angle is that it's always pointing upwards (this is why it's always positive...). I don't see any simple "trick" in the current version of CC to invert the sign of the dip angle... the only solution would be to hack the code where the dip is computed (as a matter of fact it's really simple, it's just two lines to change... but then you have to compile CC again).

Thank you Daniel.
Unfortunately I am not into programming so I will be unable to do it
