Dear Ada Folks, Here is my situation: - I'm writing some software in DEC Ada on a VAXstation 3100, - The Software uses DECWindows, - The software requires GKS-like graphics capabilities (such as coordinate transformation, clipping, ellipses...) Are there any Ada packages out there that provide GKS-like capabilities under DECWindows? I am willing to consider freeware, public domain, and commercial products. I would also consider homebrew Ada packages that have a set of basic coordinate transformations and primitive shape drawing capabilities. Thanks, Dave Gawron dgg@aplcomm.jhuapl.edu

I haven't used it, but the following is an abstract of the prolog. The ftp site is wsmr-simtel20.army.mil, and to software is in the directory PD2:<ADA.GKS>. -------- SIMTEL20 Ada Software Repository Prologue ------------ [stuff deleted] -- -- Abstract : The Graphic Kernel System (GKS) is a device - independent software package which implements - the draft GKS binding to ANSI Ada for GKS - levels Ma, Oa, 1a, 2a, Mb, Ob, 1b, Mc, and 1c. - GKS/Ada will support selective visibility, - independent VDI and VDM interfaces, the - configuration of multiple graphic device - drivers, and independent packaging of the - various GKS levels. - The complete GKS will include a prototype - metafile generator/driver, and a metafile - interprete. Device-dependent software must - be included to drive the Lexidata color rastor - device and the Summagraphics graphics tablet. - Ada software to support contour processing - requirements, including grid generation, - mathematical interpolation and contour map - generation needs to be developed. Also, - the GKS and provides for the delivery of - WIS-compatible equipment capable of high quality - 35mm color slides directly from graphics displays. - - This tool was developed as a precursor for - the WMCCS Information System (WIS). An - executable version of the tool has been - demonstrated. This source code has sub- - sequently been recompiled but has not under- - gone extensive testing.
