yes it seems that jitter support uvmap... this discution is similar to 
my concern now with gem ... :

would be great !

I have looked at the code earlier and I think that the 
"model_loader.cpp" file is parsing the .obj file for texture coordinate 
(vt lines), but it seems that the "model.cpp" do not make a call to 
these datas, only permit the choice between linear or spherical 
coordinate ...

can't say more, I'm not coder, just a lame artist fiddling with 
applications ... :)

Re: [PD] UV map - was : Google Summer of Code application is in!

[olme]

thanks ;)

nice tool ! But actually I work on linux, and I must say that blender 
has nowadays most of these capabilities (it's developped at a fast pace 
these years, orange, peach and apricot projects are realy effective at 
speeding the all things up )

the problem I have is that I can't get the [model] object to load a mesh 
with the uv map into GEM to display video as texture with right 
coordinates... (I will post a patch with .obj file illustrating this soon).
As I said in previous mails, I think it's something that was left aside 
unfinished in the code but not so dificult to fix ... or it's something 
that I do completely wrong ...
when I'll post the test patch/file, I hope someone could tell me what's 
wrong ...

I could see some improvements I would love to see (like uv map support 
for .obj [model] ) , but I don't have neither the experience/reknown of 
somebody active in the community for years (although I know and use pd 
for 3/4 years now on specific projects) nor having dev. specific 
knowledge of internals pd mechanics ... (although I do have some 
experience of lead artist in dev. of other specific app. like 
http://www.woaw.biz - nothing to do with pd -  and recent support of the 
video plugin for blender...).
I cannot say "success" in any pd dev mentoring experience... and reading 
these, I don't feel confident in taking such responsability (again sorry 
for asking stupid questions).

So it's quite off the basic requirements  maybe next years if these 
ones are prolifics for me :)

thanks for all the work you do into this,
hope other developpers and students will add to these summer 
developments, I wish you all the best,

regards,

ok, sorry I've seen it in the wiki page doc ... it seems I just ask 
stupid questions on this list until now, together with asking  uv map 
help and blender apricot ...

sorry to disturb ...

Re: [PD] [GEM] UV map for model or vertex-array ??

[olme]

Looking further into the Gem sources, I see that the model_loader.cpp is 
parsing the obj file for texture coordinate (vt lines), but it seems 
that the model.cpp do not make a call to these data, and only permit 
linear or spherical mapping that it recompute... as if uv mapping was 
not "needed" for the coders and left for future work...

I think it could only be a matter of a few hours to add the support for 
uv mapping, which is "very" useful when doing 3d scenery ... I'm ready 
to "support" the good soul that would do the job (as it could be usefull 
for me in future  projects), and I'm sure that other will like this too.

I'm not a c++ coder, and I can barely look into code for errors and 
feature...can anybody help ?
Iohannes ? you seems to be one of the maintainers, can you tell me if it 
could be done ?(maybe I'm wrong and this is realy hard work ... or 
already working with some trick ? )

Solving this would permit me to work on more than one project I'm 
waiting to finish, and I'm sure it would be realy usefull in more than 
one domain...

thanks,

Olm-e

[PD] [GEM] UV map for model or vertex-array ??

[olme]

hello,

I'm working on a project I want to show at the Shunt, London, in end of 
april...
I'm trying to play video files and streams as texture on custom 3d 
surfaces...
The features I need for this are nearly all there with Gem but I still 
cannot get one thing : simple UV mapping on imported obj models. All I 
got is linear texturing, thus it is of no use (exept for some 
experiments with moving line patern, ... interresting but ... already 
done that years ago, not my taste today).
the material parameter or any other documented in the help of [model] 
did not helped... (the obj file has a mtl file, exported from blender).

looking at the archives, I don't understand if it's possible or not, or 
if it is a future feature not already implemented... (although for me 
it's quite a standart feature I "thought" that "normaly" should be there 
in a 3d package...)
one mail pointed toward the [vertex_array] object in the CVS, but this 
date from 2006... and it's not in the PD-extended release...

can anybody tell more on that today, is it implemented or not, in which 
distrib., or do we have to wait for [vertex_array] or any other objects 
to be released ... ??

I'm trying also to use blender game engine (then with some osc <-> pd 
communication), but actualy, the video texture plugins still don't 
builds and works on linux ...

I'm in a dead end actualy, if anybody could help ...

for the story : as I was trying to get the texture right in my pd patch, 
I was also working with blender... and of course murphy came along, and 
the video texture playing in pd-Gem showed ... in my blender window, 
maped on the object fighting with the picture map I had.. altough 
neither the gem nor the blender plugin works correctly...
Sometime, it's ... funny... hum ... (some gl memory share I suppose )

thanks a lot,

Olm-e

[PD] [Fwd: Re: [OT] mini-ITX again]

[olme]

--- Begin Message ---
try the http://www.pcengines.ch/alix1c.htm or the newer 
http://www.pcengines.ch/alix3c3.htm


I used alix1c for wireless node at okno.be, not pd stuff already, but 
they are realy well dezigned and solid.
the AMD Geode LX800 (500Mhz) is x86/x87 compatible, has mmx/3DNow! fpu 
with 256Mb SDRAM, and the board has audio and vesa port already.
and they are realy cheap : around 100€ ... I was considering buying one 
for pd patches.


we installed openwrt kamikaze on it, but you can install any other linux 
like debian with ease ...


hope it helps a bit...

Hi all,

I'm back on my Mini-ITX research, hoping to use one for an upcoming PD 
installation as well as a live performance box. But what I'm missing is 
some kind of comparison of price vs functionality here. As well as some 
overview of which CPUs and chipsets are good for audio and Linux and 
which ones are not. Can anyone make a recommendation for a Mini-ITX 
system with a good processor which has proven usable for fairly complex 
PD patching with Linux, or point in the direction of a good online 
resource for this kind of info?

[PD] streaming theora

[olme]

hello,

Last month (during a workshop at okno.be), I tried to  stream theora 
over the internet as well as local network with a patch feeding an 
Icecast server... I used the pdp_theonice object for it.

basicaly, it kind of "worked", but the output (the stream received at 
client side) was realy bad : the stream had only a few images at the 
launch of the player, then only one from time to time...

The parameters seemed not to be the problem (but maybe I'm totaly stupid 
- the icecast server accepted and showed them correctly) ...  nor the 
server, wich worked perfectly with a dv cam using dvgrab | ffmpeg2theora 
| oggfwd  ... the images on the pdp-glx window from the patch were also 
ok...

Is there anyone that already managed to do a working theora/icecast 
stream ? how ? is there any other object/method I could use if this pdp 
one does not work as expected ?

(I did this on a fresh ubuntu 7.10 with fresh pd-extended )

thanks,

Ol.me

[PD] sound for blender apricot opensource game

[olme]

seeing this: http://apricot.blender.org/?p=59 , I had the idea that 
somebody could do it efficiently with generated sound dezign (like 
brilliantly discussed earlier here by andy - obiwannabe.co.uk )

In short : Blender Instituut search for a sound designer for the 
upcoming opensource game codenamed "apricot".

I'm in no way related to this instituut or project, just that I thought 
it could interrest someone that is developping on pd for games, as this 
one is already promised some exposure in the opensource/free software 
world, in the CGI world (with the short film produced right now : see 
peach.blender.org ) and in the game world (it will surely make some 
lines in game magasines) ...

I think those working for this project "in the front line" are payed, so 
it could be a good incentive to have some kind of opensource exemple of 
a current game made with pd.

Blender Game Engine has already been used with pd through py-OSC, but 
this project use the CrystalSpace Game Engine... I don't know about the 
connectivity, but as CS use python, it's maybe just some lines away

I would be interrested to see the result anyway ... as I'm not able to 
do it myself ...
