I've uploaded a first version of JPatch - a bicubic patch modeller 
similar to sPatch - to my homepage:

http://3dimensions.dhs.org/jpatch/

It's open source (GPL) and it's written in Java. I've tested it on Win2k 
and RedHat 7.3 Linux machines.

There's still much to do, but this version supports sPatch import/export 
and can output to .pov and .rib (renderman) format. With the currently 
implemented features JPatch has virtually the same functionality as 
sPatch has.

I plan to add hook and 5-point patch support (like Animation Master), 
uv-mapping, morphing and skeleton animation in future versions.

Looks very interesting.

I've just downloaded a copy of both source and executable and will be
playing with it just as soon as I can finish the modelling for my next IRTC
entry.

I'm downloading it now. I'll tell you when I'll try it.

That sounds very interesting. Keep us informed.

This is really great! I will try it out at the weekend!
I've searched for a linux capable bicubic patch modeller for years.

I must be doing something wrong. I have Sun's Java (1.4.1_01) under RedHat
7.3 (with some updates), if I type "java -jar -ea jpatch.jar" I get this
output:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/vecmath/Tuple3f
        at JPatch.<init>(JPatch.java:32)
        at JPatch.main(JPatch.java:70)

I just extracted the tar.gz binary into a directory.

Forget it, I don't have Java3D. I'll come back if it doesn't work :)

Works very nice here at a first look. Maybe you are interested in the 
console warnings below (what may be also an installation error by me?). 
Im running SuSE Linux 7.3 on a K6-2 850 if it matters.

But this is a very promising program!

How about  povray-SDL- manipulatable boning??

that's exactly what I'm working on :-)
A POV-Macro reads in the model data, transforms control points (morphing 
  and/or rotating them around the joints), recalculates the tangents and 
renders bicubic patches. Most of the code is finished, you might take a 
look at

http://3dimensions.dhs.org/jpatch/thom.jpg
(showing an earlier version with the bone-system up'n'running)

or

http://3dimensions.dhs.org/jpatch/head.mpg
(rendered with pov-ray and morphing the control points via sdl-macros
the head model is from Anto Matkovic's head tutorial
http://www.matkovic.com/anto/ )

The code was a mess so I had to start a new version of JPatch from 
scratch some weeks ago :-(
but theese things will be (re)implemented quite soon...

This could be described as a scaled down, Java based
copy of Animation:Master. I wonder how it will impact
Hash? Could be good for them, just as Hammapatch and
sPatch brought people into patch based modeling and
eventually led them to Animation:Master.

It also provides a great modeling program across multiple
platforms. I haven't tried it yet, but it looks great. I'm not
sure if it will run on my WinXP system.
