Thanks, Owen. didn't know about JaM, another beautiful rabbit hole in computing history :-)
JaM, the "John and Martin" page description language appears to come after John's Warnock's work at Evans and Sutherland on the ""The Evans and Sutherland Design System" for producing 3-dimensional graphical databases both for the Evans & Sutherland CAD/CAM Picture System and for custom-built simulation machines. At Xerox he teamed up with Martin Newell of Utah Teapot fame. all from: https://www.historyofinformation.com/detail.php?id=970 also interesting bit at end: "While it is difficult to separate the contributions made by Sproull and Lampson, it is not incorrect to say that Lampson and Warnock produced the execution model of InterpressOffsite Link while Sproull and Warnock produced the imaging model. It is also approximately correct to characterize this first version of Interpress as being derived from the graphics model and execution model of JAM with additional protection and security mechanisms derived from experience with programming languages like Euclid and Cedar, and a careful silence on the issue of fonts. The trio worked under Geschke's direction, and Geschke was responsible for refereeing disagreements and for making certain that the resulting design was acceptable to the rest of Xerox" again, I think there is something repeating itself as we're making digital twins of the world with geosimulation and GIS drawing tools and searching for standards to describe dynamic scenes (not just a page) in a platform agnostic way. Hence our 3D tiles, glTF and Universal Scene Description <https://en.wikipedia.org/wiki/Universal_Scene_Description>, CZML, geoevent servers, but also wanting the realtime animated. note the relationship to reatlime pose information in "Full Motion Video <https://docs.ogc.org/per/20-036.html.>" MISB (motion industry standards board) Also the standards around geospatial optical features in the world (eg OpenAR Cloud <https://www.openarcloud.org/>) _______________________________________________________________________ stephen.gue...@simtable.com <stephen.gue...@simtable.com> CEO, https://www.simtable.com <http://www.simtable.com/> 1600 Lena St #D1, Santa Fe, NM 87505 office: (505)995-0206 mobile: (505)577-5828 On Thu, May 18, 2023 at 11:40 AM Owen Densmore <o...@backspaces.net> wrote: > On Tue, May 16, 2023 at 10:48 AM Stephen Guerin < > stephen.gue...@simtable.com> wrote: > >> Thanks, Steve!
