Quake on an Oscilloscope

Map E1M1 of Quake on a Huawei V-422 oscilloscope. The rendering is done with a laptop and the scope shows the generated audio signal as two dimensional vector graphics. Finnish project 8-)

Well, for me this even beats playing Doom on a calculator ;)

Happy new year to you all !

the interesting thing in this video is to understand how it's achieved more than the result.

I think a little more explanations are needed.

The image is transposed in simplified meshes, then modulated in audio signals to match the oscilloscope reception format at the proper frequency.
It does come tricky with the framerate. In fact with the same algorithm, depending of your oscilloscope you may encounter curves instead of lines, it will depend on the samples used/generated and your impulse frequency per refresh.

It may not look this impressive, but the interface between the computer and the the render is quite very good a piece of engineer's work.

and the basics for those whom want to know more on the interfaces used in vector render : http://www.jmargolin.com/vgens/vgens.htm

good luck :)

Only a few people will understand and admire what is going on here. This is just awesome!

I rather don't care how many times the earth has orbited the sun since a purely arbitrary starting point...

Great!
I recognize Quake I even in an osciloscope. Hard to forget the dobermans.
