Does anybody know of any graphics packages for the PC. I've used BGI and Halo, but was wondering if there was anything like maybe GKS, CGI, CORE, PHIGS etc. In particular 3-D packages for the PC would be helpful to a lot of people.

The digital research GEM/3 system extension foor PCdos , includes a pretty complete implementation of the CGI/VDI graphics interface... -- Automatic Disclaimer: The views expressed above are those of the author alone and may not represent the views of the IBM PC User Group.

It allows control over several graphics devices simultaneusly without regard for their individual features. It also provides programmatic support for mouse-driven pop-up menus, icons and the like. >In particular 3-D packages for the PC would be helpful to a lot >of people. I would suggest you wait for their Xenix X11 implementation for 386 PCs expected to be there in May. Manoj Joshi. (415)857-7099 manoj%hpldas5.HP.COM@hp-sde

Most of the time, "CGI" refers to a graphics standard in the making (in ASC X3H3.3 and ISO SC24) called "Computer Graphics Interfacing Techniques for Dialogues with Graphical Devices", shortened to Computer Graphics Interface (CGI) in common usage. This was originally called "VDI" for Virtual Device Interface when it was started around 1980, but got renamed mid-stream when the Virtual Device Metafile (VDM) entered the ISO arena and became Computer Graphics Metafile for the Storage and Transfer of Picture Description Information, or Computer Graphics Metafile (CGM) in common usage. The CGI is not yet a standard, although it is expected to be within about two years. Along the long and arduous path to standardization, several companies have come out with "their" version as products on various hardware/OS platforms, sometimes taking the liberty of calling them CGI or VDI. (These products are usually based on a snapshot of what the standard-in-progress looked like at a particular time, plus whatever modifications, enhancements, and extensions that vendor chose to offer to meet real or perceived market needs.) None of these will match the standard when it is done; some of them may be revised after the standard is done, but who knows. From the sentence in which it appeared, it looks like the original poster is looking for something that is actually a standard - which is a good way to gain application portability and vendor independence. There may be existing products calling themselves CGI which do what is needed as far as functionality, but until there is a true standard the would-be CGI user has no guarantees that their code will port to any other CGI.
