I skipped the obj files now.

I made a version now using **[geomerative](https://github.com/rikrd/geomerative)** library (seems not to be in the download section of the IDE.

see [Hair like strokes](https://discourse.processing.org/t/hair-like-strokes/10143)

With geomerative I read the points from each letter and then extrude it.
