EGS, Enhanced Graphics System
« on: April 04, 2020, 06:58:47 PM »
An amazing piece of Amiga history



EGS , for Enhanced Graphics System , is a solution developed by the German company Viona Development. Released around 1991, it has offered a complete RTG system for Amiga, including:
  • a hardware abstraction for all 24bit graphics boards that supported the EGS standard
  • a very advanced GUI that took full advantage of the Amiga multitasking and the capabilities of 24-bit graphics cards

EGS was written in a new language called Cluster, described by its author as an evolution of Modula-2 (itself being an evolution of the Pascal programing language).

The first presentation of EGS to the general public in the USA, operating on a GVP graphic board, took place in April 1992, that means 3 years before the official release of Windows 95.



How can I test EGS?

Although designed to operate on an 8 or 24bit high resolution framebuffer, EGS is fully compatible with the builtin ECS and AGA graphics modes.
Therefore, it is quite possible to install it on an Amiga Classic (as long as you have a 68020, enough available RAM and if possible an FPU).

The latest version can be found on Aminet. The software even works perfectly under the UAE emulation!

The EGS system automatically adapts to the amount of available colors, thanks to an automatic dithering and color palette system.

The look & feel of the GUI under EGS

Taking its inspiration from the workstation's GUIs like X11, IRIX or NextStep, EGS shows a very polished and consistent look.

The features and ergonomy are extremelly advanced for this generation, including a docking system available for every drop-down menu and window opened by the EGS applications as well as a global object-oriented approach.



Screenshots, boys & girls!

The system preferences of EGS are similar to the one found in AmigaOS, pushing the features and ergnonomy a step further.


 

 


Some demo applications show off the awesomeness of the GUI, the graphic layer and the infamous multitasking of the Amiga. EGS provides a very advanced and accurate performance monitor that details the delicate complexity of AmigaOS.


 

 

 


A builting image viewer offers several resizing modes (nearest, linear, spline...) with more or less fast / accurate interpolation.


 

 

 
The text editor mentions, in its "About ..." window, the Cluster language on which the EGS is entirely based.

Only Amiga? ... :)
