Polynomial Texture Mapping : .PTM files

This question is prompted by Neil’s Antikythera threads, but it’s a simple question about file viewers; so probably best kept separate:

There are 82 images available on this page: **LINK**

http://www.antikythera-mechanism.gr/data/ptm/full-resolution-ptm

Some of which I would like to view [preferably on the iPad]

The PTM viewer linked from that page seems to be an ‘Antiquity’ in its own right !

https://www.hpl.hp.com/research/ptm/downloads/ptm_viewer.htm

I have, however, found a more modern page, which looks promising: **LINK**

http://shiftleft.com/mirrors/www.hpl.hp.com/research/ptm/downloads/download.html

… it even mentions a Mac version.

Before I disappear down the rabbit-hole, does anyone know of a PTM viewer for iOS

Thanks

I'm still lost … but have just stumbled across this page on the Wayback Machine : **LINK**

… and this comparatively recent page:

Try RTIviewer from CHI Michael. (Can't test it myself because daughter has left home with her Mac.)

My problem is getting a Viewer to run on Linux! Just hit a 32-bit iceberg.

Will do, Dave

… Many thanks

Edit: __ That works a treat with their Papyrus file 

… Now to try it with some of the big images

All looks good so far

As a final note of thanks, Dave

I’ve also found that there is a web-based viewer [albeit with less functionality]
