LED CHALLENGE!

Welcome to the LED Challenge!

A chance to make something really flashy!

There are LED's all around us, you'll see them on your modem or router, on some of your household appliances, on motorway matrix signs, in shop windows!
They are everywhere, and they come in all kinds of colours these days, some of the signs are quite beautiful, here's a mundane one;

But it's still effective and you can see that having a matrix of these LED's makes it possible to display some eye catching messages.

Now consider this..

RGB
BRG
GBR

R=Red Led, G=Green Led, Blue = Blue Led.

You could actually pack coloured LED's into the matrix in any order you like.
Hopefully your imagination is fired up now!

This time We'll run the comp for longer so you have a month to make something! So maybe your LED demo can have a Christmassy theme!

Here are the rules!

• if 2D matrix used: Maximum matrix size of 512(x) * 256(y) or Maximum amount of LED's  131072
• if 3D matrix used: Maximum amount of LED's 131072 (512*256)
• You may use any combination of colours for your leds but each led must be a single colour only. for example a red led is red and not any other colour.
• You can vary the power to your LED's so you can have infinite brightness settings for each one.
• Your demo must contain an led matrix displaying one or more effects
• You can use any playform that is compatible with windows XP+Vista.
• You may write something for web browsers as long as it works in IE7 or FF3 (or both!)
• The following emulators are welcome: Vice, Winuae, Saint, PS2 Yabasic
• Please give credit if you use ripped sound/gfx, or even better credit the original artist.
• Please write something new for the challenge, no previously released stuff.
• Do not use ripped routines. (dlls, libs, fmod, sdl, frameworks etc are fine but say what you used please!).
• Enter as many times as you like.
• Entries to be posted in this forum please with the title [LED] entry name
• Entries may be posted between NOW and Midnight of [20th December 2008]
• The winner [S?] will be decided by a poll of forum users

Here are the prizes!

• 1st Place  - Sig - 20 Karma
• 2nd Place - Sig - 15 Karma
• 3rd Place -  Sig - 10 Karma
• All entries get 1 Karma

Good luck!

I want to thank Relsoft for the idea for this challenge.

Cheers mate!

Sounds neat idea! I really hope I have time to code something for this kompo!

EDIT: Can this demo have other stuff than leds in it? Like the surrounding environment etc

Oh yes, abosolutely!

[combatking0]

Can we have a matrix of 512x256 for red, another for green, etc or do they share a single matrix?

[Shockwave]

all share a single matrix otherwise you'd lose the effect and you'd just be down to pixels. 512 *256 is pretty generous though

[combatking0]

Ah, I see.

Time for a fresh coding session.

[hellfire]

Maximum matrix size of 512(x) * 256(y)

What about 3D matrices?


...or tubes?

[Shockwave]

Great idea! I added that into the guidelines.

[Hezad]

Funny comp I guess we'll see cool and imaginative stuff again !

I'd like to propose something this time but I don't have any cool idea (yet ?). But if I find time and an idea, I'm in !!

[Shockwave]

I'd say make something with LED's

[benny!]

I'd say make something with LED's

Yup. I would recommend LED's, too. ;-)
Cool competition - hope I'll find the time to enter it!

[Hezad]

  LED's are planned :p I'm now looking for an idea about what to display on those leds ^^

[Shockwave]

Your 3D engine?

[Hezad]

In fact I just got an idea concerning 3D ^^ but not really using my engine

(I tried to use my engine -and it was a really good test in fact- but there's a big problem in the "generateobj" procedures, I mean 2 minutes to build 16 spheres, it's a bit long XD )

what about you ?

[Shockwave]

I am going to do something in Opengl I think

[Pixel_Outlaw]

What about those LED signs that only have 4 or 5 LEDs that rotate rapidly and create an illusion of more? I don't know the technical term. Is that acceptable?

This just has a swinging arm with a single line of LEDs in it I think.

[va!n]

@Pixel_Outlaw:
wow, that object is really amazing... is the scroller on it programable? if so, any idea where to order/buy such a thing or whats the name or company of?
Thanks! Just awesome!

[Shockwave]

P_O, as long as you use LED's it's fine

[Hezad]

what Va!n said :p Where can we get this thing ? I knew the "led on moving arm" object but this one looks particularly awesome o_O

[Pixel_Outlaw]

Sorry guys I just found this myself, no idea.
