I have several PTM (Polynomial texture mapping) files that I would like to read in either Python or R for visualisation and computing measurements. I'm not sure how to read these files and would like to work with the X, Y and Z coordinates ideally.
Examples are found here: http://palimpsest.stmarytx.edu/integratingdataarchive/Pal1/Acce/

- 20140220-Pal1-45-Acce-04-50m-e.ptm
- 20140220-Pal1-45-Acce-04-50m.ptm
Background information of how to build and view these files are found here, it is essentially a rayshading technique: http://culturalheritageimaging.org/What_We_Offer/Downloads/Process/ http://culturalheritageimaging.org/Technologies/RTI/
Thanks in advance for any help or pointers in the right direction.
