Hexagon is a subdivision modeler owned by DAZ 3D. It was originally developed and published by Eovia and was acquired shortly before the release of version 2.0 by DAZ in 2006. The software drew heavily on Eovia's other modeler, Amapi (it shared the same developers), though it omitted the NURBs and precision measuring tools. The main focus is Subdivision modeling but it includes Spline tools and surface tools. Because of the two omissions, it is not as well suited to product design as Amapi, but is aimed more at illustrative and character modeling with an eye to making it accessible for those new to working in 3D.
Version 2.0 saw the addition of UV unwrapping tools and a selection of 3D painting tools were added, though these are still quite basic and do not include layers. Also added was the facility to paint in displacement - or "3D sculpting", which makes Hexagon particularly well suited for organic modeling. All of this can now be previewed within Hexagon using its new Ambient Occlusion.
Hexagon continues to be developed under DAZ's ownership with version 2.2 released in June 2007, and version 2.5 released in March 2008.
Hexagon is strictly a modeler. It does not render or animate. It would be used to create a model with low resource overhead before exporting to render/rigging/animation software like Project messiah.
