Vector graphics in your terminal just like in the 70ies

In the early 70ies, RFCs 192 and 493 already proposed remote graphics that would be rendered in terminals. Simple serialized commands draw lines, curves and shapes. The idea has been implemented in many ways since then, and even today, SVG is based on the same primitives. Can we still do that in our terminals?


In this workshop, we will look at ReGIS, the Remote Graphics Instruction Set that DEC (Digital Equipment Corp.) had implemented in successors of their famous video terminal VT-100, which is still present in the xterm terminal emulator. With a few simple commands, we draw our own shapes, print text in various sizes, do rotations, animations, and create little demos.
