Professor Lipson invited me to the group to announce our latest software release, so apologies for the advert.

Polygonica, the Polygon SolidModeling toolkit from MachineWorks, is a software toolkit for carrying out a wide range of geometric operations on 3-d models such as automatic solid healing, fixing self-intersections, slicing and other Boolean operations. See http://www.machineworks.com/polygonica.htm and http://www.machineworks.com/news-2011-11-03.htm

 

To support customers in Additive Manufacturing we have extended the existing input and output file formats to include AMF.

 

As a developer I was impressed with the clarity of the specification and we were able to quickly develop the XML parser and encoder for the 3-d geometry.

Coming late to this group a couple of features of the specification seemed curious. Maybe someone can assist with a brief history lesson ?

 

1.  Compressed format.

 

A compressed data file may take less file-space but takes longer to parse. Why was this option chosen rather than a binary format ?

Is there a reliable way to spot a zipped file when opened ?

 

2.  Restrictions on geometry. 

 

The specification suggests that objects not of type "support" must comply with all the restrictions on geometry.

Should it fail to parse, or just warn users ? Must any AMF parser contain the functionality to validate the geometry ?

Polygonica provides all the functionality to validate the geometry and automatically repair any problems found.
