Nice Camera Moving

Spring physic rules. I wanted to code the exact same thing, but I’ts already out there. A chasing cam.

Deichkind = Hell Yeah!

Gestern war ich endlich auf dem Konzert auf das ich mich schon seit 3 Monaten freue. Es war ziemlich exakt wie auf diesem Video. Ein Club auf dem Kiez (Docks) – bekloppte Menschen – und Deichkind.

Die Bühnenshow oder wie man das auch immer nennen mag war einfach nur FETT. Als Limit angespielt wurde gings mit Sebastian in die erste Reihe. Als zugabe gabs dann nochmal Remmi Demmi. Wie geil das war kann ich leider echt nicht in worte fassen aber dafür is ja das video da.

Kurzum: Ein Traum!

Ich hör jetzt weiter arbeit nervt und widme mich wieder meiner Arbeit ;)

I love the idea. It’s not new but very well done.

physics is cool

Thanks to Jens Franke for that link. It’s so cool! A train is “flying” over a magnetic rail. This is accomplished by an ultracold liquid.

Webcam and papervision3d

This night I saw this

So I wanted to try this in papervision3d. Well it is possible but there are some depth problems.

arToolkit and papervision3d

Too sad that my french and japanese is really bad. I recently found a great arToolkit demo for flash called FlarToolkit. After randomly clicking all the links I could find on the page, I found the svn :-)

I had a compile error using flex sdk and eclipse. after changing a private to public property it worked.

It performes really well but you can also see that I is still not really stable. I think the major bottleneck is the bad webcam quality compared to a dv cam.

What I don’t get:

When the FlarToolkit has found the rectangle in the “2d” image, how can I transform this data in the papervision3D room. If you have a 2d->3d math for dummies link – please drop me a line.

What I would love to do:

As you can see there are some serious tracking precision issues. In my opinion the major problem is the pixelbased tracking. It’s a waste of performance. This could be solved by an Idea Mario Klingemann presened on the FFK08 called blobdetection.

Well this is my theory:

  1. Blur the camera image and convert it in black / white image
  2. With getcolorBoundsRect and floodfill detect all black rectangles in the image
  3. Find the marker rectangle
  4. Use an edge detection
  5. You should be done

So you only need to analyse a small amount of pixels directly for the edge detection. The other stuff can be done by “internal” flash functions which are really fast. Maybe I’ll try it – someday.

As far as i got it, the tracking was done with a dv camera and an ir filter. You can find detailed information about it in the comment section here
