[odeforjava-devel] ODE for Java v0.2 released

[Tim S. <ti...@un...>]

Hi!

Just a few minutes ago I released ODE for Java v0.2


Features:
---------

ODE for Java is now splitted up in
- a core package that represents the pure JNI binding to ODE.
- an extension package that contains additional features that
   need source changes or additions in the original ODE
   distribution.
- a java3d package that provides a scenegraph representation
   of several ODE objects and comes with behaviors for setting up
   the simulation loop.

The JNI of ODEforJava v0.2 is designed to run with ODE v0.039 and should 
cover most of the ODE functionality that is available in that 
distribution (no OPCODE).

The source packages are delivered as Eclipse projects with (to be 
slightly adjusted) ant scripts that generate JNI header files and create 
the final library on linux systems.

An MSVC project is included to build the library on Windows systems.


Remarks:
--------

I know there is another JNI wrapper for ODE on dev.java.net called 
odejava. As far as I found out it uses SWIG to generate the JNI binding 
automatically which is a promising approach regarding the production of 
less error-prone software and being always close to the development of ODE.
Nevertheless I wonder if this automated wrapper generation also accounts 
for all ODE-specific inner object dependencies in conjunction with java 
garbage collection.
If anybody makes or has made experiences in comparing these two projects 
especially with regard to this issue I would be glad to hear about and 
learn from that. I want to emphasise that I do *not* mention this to 
make another project bad. Far from it! Please test both. ;-)


History:
--------

After the first version v0.1 had been released by me in Nov. 2002 Max 
Gilead established the sourceforge project and put the sources of v0.1 
into it.

In Jan. 2003 he released the core part as v0.11 with helpful changes 
regarding java3d dependencies and gcc issues. A complete rewrite was 
under consideration but has not been done.

In Mar. 2003 I included some of Max's changes into my own trunk and 
started development to adapt ODEforJava to ODE's new collision detection 
architecture. The development continued but without any updates to the 
sourceforge site.

In conjunction with another project that deals with simulated physics 
and augmentated reality (check out 
http://sourceforge.net/projects/jartoolkit) I restructured and revised 
the sources and made my ant script (hopefully) useful for other people, 
too. Today I released it as v0.2.

[odeforjava-devel] Problems getting results out of ODE for Java

[Malc C. <mal...@ho...>]

Looking for sample ODE For Java code....

I'm working on distributed Robot simulation for a Masters Degree with ODE as 
the physics engine.  I've installed ODE for Java on a Linux box and the 
install seems fine, and my Java code compiles OK.  I have converted the 
buggy_test program from ODE to Java and I'm trying to get it to print the x, 
y to System.Out rather than use OpenGL like the original C program.

I'm using Body.GetPosition to try and get the body's location but all I get 
back is NaN instead of a number.  I can call other functions OK, for 
example, I can set and read the mass with no problem.

I've searched the Internet but not found any sample ode for ODE For Java.  
Does anyone have any sample code they can share to point me in the right 
direction?

Thanks,
Malc
