Haskell ASCII 3D wireframe animator

Animates wireframes in a 3D coordinate system using only plain text and a few control codes for cursor movement. This video demonstrates coordinate systems with a single point marking the origin, a static cube and a few different animated cubes.

The math used is simpler (and less correct) than what real 3D engines use, which results in visual oddities in some cases.

The background music is Lambda Fantasy by Foldplop (that's me!) and the animations at the end are a couple of random Quartz compositions I put there to make the lengths of the video and audio tracks match.

damn man! just stumbled upon this! Amazing music! And lovely haskell thingy you got there! got me all fired up! :D i hope to find your songs somewhere!? :D

@bitmefool Thanks! :3 I have a couple of releases up at foldplop . com. You can also find a few tracks released at demo parties (including Lambda Fantasy) by going to scene . org and entering "foldplop" or "cross dressing robots" into the search box.

Incredible! I would love to see how you worked out the characters screen co-ordinate based on its distance from your view position. Did you manually create some sort of a depth buffer?

[VIPSTARHinaichigo]

@CallumBGood I wrote this before having properly studied computer graphics and used some kind of odd scaling formula that breaks in many corner cases. The standard way would be to apply a perspective projection from 3D to 2D. Since this is just a simple wireframe rendering without culling of invisible faces, there's no depth buffering going on.

I love ur music bro. I just sit here all day listening to it

[TheSum1005]

oh my god, cross dressing robots

[sharperguy]

Also please tell me what that music is!

[sharperguy]

Oh god I love lambda functions. I've been programming in python for years and didn't realize it had them.

Why in Darwin's name are you using Nano? -_-

[chrismofer]

i want to do this in batch programs for a loading screen, is there any way you could send me the individual frames for just a spin in actuall charactors and not a picture?

thanks.
