halcy.de v4 » Version four-point-oh and counting.Two weeks!

So I got a 3DS, and after noticing that it uses an open format (“mpo”) for storing 3D photographs, I needed to play with that, of course.

As a result, I now have a version of my simple raytracer that can render a left and right image, which can then be combined into one stereoscopic 3D image for viewing on the 3DS with software such as this (It runs under wine).

I’ve rendered two small scenes, a 4D julia set and a trefoil knot of spheres! They look kind of neat, so if you have a 3DS, put them on your SD card in the picture folder and have a look!

(If you don’t have a 3DS, you can still look at them as if they were normal jpeg images, because they really are jpegs with some added exif data)

• Image 1 - Julia Set
• Image 2 - Trefoil knot
• Raytracer
• Program for converting left/right images into mpo files
• Bonus: WAHa_06x36 took pictures of his bismuth crystal, which I cropped and converted! They look neat, also!

P.S.: My friend code is 0473-7758-5435~ feel free to add me~

Something I sort of completely forgot about.

At the GulaschProgrammierNacht 10 - the entropia ev/CCC Karlsruhes annual hacker event - I held a talk about modern OpenGL. While the talk itself wasn’t held very well (I rushed through everything aaaaaaaaah oh god), the base material is, actually, a pretty okay introduction to modern OpenGL - without fixed function pipeline, as it should be.

You can download the english version of the slides here, and - probably more interestingly, can grab a copy of the demo program I made, which is very well-commented and does nothing but simply render a rotating cube, as seen below.

If you’re the type that learns best from examples, have a look.

Also, if you need more writing and explanation, have a look at Joes blog, where a longer explanation of basically the same thing is provided. :)

So, over the weekend, I went to Evoke. Evoke, for those who don’t know, is a Demoparty, a sort of gathering for people who write Demos to get together, show off their newest works in the competitions, talk, and potentially get mightily drunk.

We didn’t actually plan to release anything at the party, but after arriving after a 4ish-hour-drive (Drove there with Maep and Saga_Musix, took a few wrong turns… <.<) I suddenly felt like coding something up for the DS. WAHa_06x36 and coda were availble to assist with additional effects, graphics work and music, so in 16 hours of intense partycoding, during the course of which I downed half a crate of club mate and nearly threw up my breakfast, we’re able to give you:

Our release was generally well-redieved, and finished second in the “Alternative Plattform” compo. We even got Prizemoney this time around, which was a little unexpected.

One of my favourite demos of the whole party was this 64k intro (It’s 64k, despite what it says in the video). Beautiful use of… cubes! It won, too! <3

Something I sadly only found after the party was over is the full version of this years party jingle, mmsx#001 - dq feat. scraping micha - this year. Absolutely lovely.

In conclusion, Evoke 2010 was an awesome party, massive thanks to the organizers - especially to the beamteam for the recording, you’re awesome - and to brainstorm for free sausages and alcatraz for free beer. o/

The next demoparty for me will probably be the 2010 edition of the ultimate meeting, right here in Karlsruhe, or maybe a party up in finnland! See you there!

So, over the easter weekend, I went to Breakpoint, a demo party in the wonderful “Bingen am Rhein”. Since I like the invitation to that a lot, have a video of it to start off this post:

It was awesome, as always; Demos were released and enjoyed on the bigscreen, beer was consumed, people were drunkenly hugged, and a great time was had by all, as evidenced by my own pictures at flickr, and some more pictures over at slengpung.

Speaking of releases, here’s two: First, our [SVatGs] release for the 4 kilobyte intro competition, which placed 9th out of 18! (Upper half! Yeeeeeeeeeeah!) 4k intros are demos that have a size of only four kilobytes. For comparison, this tiny image, which I randomly picked out of my misc folder, is 10k big - more than twice that!

And then, there’s my favourite entry from the demo compo, because I like things what are colourful and blink a lot: United Force / Digital Dynamite - Wir sind Einstein. [on pouet]

Overally, it was a great weekend, and it’s impossible to thank the BP orga team enough for making it possible. I hope that some people will get together and pull off a party as awesome as this next easter, now that breakpoint is over with~

Until then, let’s remember the most important (most important possible) announcement, and see you at the next demoparty. :3

It’s UNIQLOCK, customized for Karlsruhe, running on a panel hanging on my wall! WALLQLOCK!

The construction of the frame is pretty terrible, but the end result is kind of cool. There is actually a whole notebook computer in that thing.

It’s a scroller, of sorts. Sort of.

• Youtube video. Quality: Horrible.
• Lunix version.
• Windows version: Yeah sure, just as soon as I feel like figuring out how to put single pixels on the screen somewhat fast.
