BIO
born in 1962 in Lier, Belgium.
studied filology at Louvain, Belgium.

worked a lot in bars and restaurants before i became obsessivly addicted to producing stuff on computers.

i once won a design contest of cgi-magazine and they let me go to New York for four days, that was nice.

i think in terms of writing mostly (or programming, but those are very similar processes for me)

painting is a very different process and i'm very bad at it but i do it anyway because i like the differences it produces and i like the freshness of amateurism, i guess.

what i produce new media-wise is also very much influenced by my daily practice of webdesign and programming with its concerns of usability and the pragmatic approach it implies.

new PCU version


version 0.4 of the Pluggable Cathedral Universe, a flash app visualising
Cathedral usage: now you get an animated representation of Cathedral places
based on user data (pagehits)
( kinda re-inventing the circle on a saturday night...)

BW version on the homepage http://www.vilt.net/nkdee
colour version at the East Gate http://www.vilt.net/nkdee/east/index.jsp

both are Flash 7 - source fla on request

usage:
- select a symbol to select a place (drag 'm out)
- click 'visit' to open place in new window
- click 'draw' to generate a rotating thing based on userdots floating
around invisibly (cfr other flash version at
<http://www.vilt.net/nkdee/east/flash2.jsp>
http://www.vilt.net/nkdee/east/flash2.jsp to catch a glimpse of those)
- you can adjust the number of angles by typing a number in the RES box -
keep the number low if you're using an 'old' machine

greetings,

Re: Re: Re: Re: Re: Re: 3D Holographic projectors?


Indeed. No screens/displays. A (foggy, blurred, i don't care) appereance of
the Cathedral hovering 3m from ground level over a square building (5x3,5
m). And it does need to be (highly) responsive to user input, changes can be
minimal (eg colour change)but need to be distinctive visually. The show will
be revealed in Kessel-lo on september 27, 2009 at 0:50 local time. Next
year, an international engineering competition will be initiated to supply
me with the required technical equipment. Judging from the amount of money
Nad mentions here, i guess i'll have to fool some companies into believing
they can make a profit off it. I'll make a 3d mock up of the project later
this year. Business people get delirious when they see complicated 3d mock
ups with a deadline underneath it.

For now the project is best viewed in your dreams. Try eating some orange
flavoured chocolate (preferrably Belgian)while reading this , concentrating
your thoughts on the project. When you go to sleep you only need to put
another piece of the said chocolate in your mouth, let it melt, dream away.

Impatient artists wishing to contribute to the project at this early stage
may forward suggestions of a (working) title for the project to dv@vilt.net.
Another thing you could do is start whispering to each other about it while
commuting to your place of work. You might not be aware of it, but
contemporary artists are known to commute to work in the presence of eager
business people. Just make sure they think they just got a headstart on the
competition.

Re: Another 3d Engine


Thanks for the explanation. It's an interesting approach. I started using
Processing for Java things recently,do you know it? there's a growing
artistic community sharing experiments using the Processing tool (see
www.processing.org).
Anyway, keep us posted on your work!

Re: Another 3d Engine


Andrei,
It looks very intruiging. Could you say something more on the nature of your
modifications? Most of them seem related to the temporal aspect of the
rotation, using previous frames as feedback for rendering the next frame
perhaps? Or are you mixing perspectives on the virtual object?
