Vector based displays were used for arcade games in the 70s and 80s. A typical CRT uses raster graphics, which are displayed by deflecting a beam in a grid pattern onto a phosphor. A vector display deflects the beam in lines rather than a full grid, drawing only the needed vectors. Perhaps the best known vector game is the original Asteroids.
[Jeremy] built up a RGB laser projector, and wanted to run some classic arcade titles on it (http://jv4779.blogspot.ca/2013/03/laser-projector-playing-mame-vector.html). He started off by using the XMAME emulator, but had to modify it to communicate with the laser and reduce flicker on the display.
To control the laser, a modified version of OpenLase (https://github.com/marcan/openlase) was used. This had to be enhanced to support RGB color. The modified sources for both the MAME emulator (https://github.com/jv4779/openlase-mame) and OpenLase (https://github.com/jv4779/openlase) are available on Github.
[Jeremy]s friend, [Steve], even got a vector based game that he wrote working on the system. World War vi (https://github.com/smcameron/wordwarvi/tree/open-lase) is a shoot-em-up battle about the vi and emacs text editors.
The results of the build are shown in a series of videos after the break.
