Export signed distances as intensity values

Post by gil »

Dear all
I want to export my signed distances as intensity values (for example mm). It is possible?
Thanks Gil

Since the distances (signed or not) are stored in a 'scalar field', you can export your cloud to ASCII, PLY or even LAS, and keep the information 'as is'.

But if you really want an 'Intensity' field (such as the official LAS 'Intensity' which should be between 0 and 65535), then you will have to rework the scalar field first so that all the values fall inside the expected range (with Edit > Scalar fields > SF Arithmetic).

Last option, if you want to export this field in fact as RGB colors, you can define your own color ramp (with Edit > Scalar fields > Color scales manager) or use a default one, and then use 'Edit > Scalar fields > Convert to RGB'.

Hi Daniel,

Thanks for the reply. However it is not obvious for me how two export the reworked scalar field as Intensity field?
In fact, renaming the scalar field as intensity it doesn’t work.

Have you written 'Intensity'? (with a capital 'i')
