Reliving Tom Hudson's interest in 3D graphics, he adapted his Solid States program for the Atari ST (originally developed for the 8-bit Ataris, Atari 400 and Atari 800). In August 1985 he left the ANALOG magazine and shortly afterwards he published two other programs for the Atari ST that were quite successful among Atari users: DEGAS and DEGAS elite, both programs to paint. In 1984 he published one of these programs, a small 3D renderer: Solid States. He had been doing a little of everything in the small group that was running the magazine: writing articles, creating games and other programs. On the other hand, programmer Tom Hudson, another pillar of the Yost Group, from 1982 to 1985 had been working for the other reference magazine within the Atari world: ANALOG Computing. The Cyber Studio, antecedent of 3ds Max The combination of direct collaboration between programmers and users was essential in making possible the next development of graphic software. The online arm of his graphical community was Cyber Connection, a CompuServe forum that provided official developer information, as well as a whiteboard system where messages were left to discuss.
Gary Yost saw the potential that was contained in this "user community", making it an official part of software development for Antic. On the other hand, these forums provided a means for Atari users to interact with each other. Thanks to this service, Gary Yost was able to speak directly with a large number of users, who in turn later bought and used the software they produced from Antic Software. One of the most visited belonged to Antic. One of these new servers was CompuServe, which housed several Atari forums. In the development of The Catalog influenced the small development that had occurred in the communications through Internet, with the beginning of servers. From his position in Antic Software and with Jack Powell created The Catalog, a compilation of programs for the platform Atari. The gestation of the Yost Group began in early 1984, when one of the most important Atari magazines, Antic, created its software section, Antic Software, headed by Gary Yost, who had been working for the Atari company. The origins of the 3ds Max program could be placed in the mid-80s, with the formation of the so-called Yost Group.
