Seven Red Lines SOLVED
SRL – Technical Discussion
Re: Seven Red Lines
Via #1 Son:
Thought you’d appreciated the discussion at my work about this:
TC Embarrassingly, I’ve done the opposite in meetings.
Requester: I want two perpendicular lines.
PM: Drawing two perpendicular lines is really hard. No resources for it.
Dev: Actually, I can do that in an hour.
PM: /facepalm

JH Increase the dimensionality and you can certainly get 7 lines all perpendicular to each other.

JH As for the color part, I feel like there was an xkcd about this recently…http://xkcd.com/1351/

JC Projecting seven dimensions down to two dimensions doesn’t seem to work very well. Also, the colors are wrong.

GM but the question is, can you make them red and transparent?
