DIET 3D : FREE 3D ENGINE DEMO (JAVA / J2ME) FOR MOBILES


Language :
English
French / Francais
About :
The idea is to provide a FREE Open Source Real Time 3d engine for phones and mobile devices.
Currently don't expect to play quake on your device, but it can display spinning logos with lightning (like old-school demo of early 1990s).
Upcoming, Features are : texture mapping, Rubik's cube game

Main Features :
Portable to MANY devices (vs native 3D)
Rendering Modes : Vertex, Wire-frame, Filled, Color, Back-face Culling, Dynamic Lightning (Fresnel), Triangle Filler, Z-Sort


Requirements :
It is available for different profiles more or less based on MIDP API (Mobile Internet Device Profile) : Supported device are too long to mention (today Diet3D has been tested over 30 devices, see testers)


Contact :
Project URL is : http://rzr.online.fr/java.htm
I started this stuff as a showcase of my skills in the Java Programming Language.
I also have a résumé online , and I am to hire : http://rzr.online.fr/job.htm
You can reach me Philippe COVAL at http://rzr.online.fr/contact.htm for Questions, Remarks, Ideas, Features Request, and bug reports
Project Official name is Diet3D (because Mini3D was already one of my project)

Support Author & Software:
Because I am not paid (so far) for this project, it does not mean that I don't need encouragements : http://rzr.online.fr/help.htm
Please Can you visit sponsors at top/bottom of the page (I'll get a few cents)
Also contact me if you want a specific 3D logo for yourself or your company. I can charge a few bucks for that (or making some documentation).

Free & Licence :
It is GPL Licenced That's mean you can afford it for $0 and for $0 extra you'll get the source codes.
BUT you have no right until you read this : http://rzr.online.fr/license.htm

Contribute :
PLEASE reports me your tests, patches, documentations are also welcome, (I can set a CVS up if needed)

Download Byte Code & Sources (GPL Licenced)
There is a GPL version of the sources (midp1.0 wireframe only) at : http://groups.yahoo.com/group/rzr-en/files

Current version of the sources are not public (contact me if interested).

Please visit sponsors or donate, for speeding up project.

DOWNLOAD & INSTALL


On a Real phone device (Over the Air, with WAP, GRPS or BlueTooth)
If you open this page with your mobile (it detects, wap or html) and select .JAD link (or .jar if problems)
http://37337.free.fr/
If having trouble with this address, you can try this alternate ones (SE dont support redirection)
http://rzr.online.fr/wap.wml
http://rzr.online.fr/wap.html
It should install by itself (fast , because it is less than 10Kb)
On a Real phone device (Beam it with cable,Infra Red,Bluetooth etc)
Pick the both files .jar & .jad

DEVELOPER DOCUMENTATION

Environment & Tutorial
Linux J2ME + Tutorial
The problems & the tracks
no java.awt.* : nevermind we dont use them just Graphics
java.awt.Graphics ~!= javax.microedition.lcdui.Graphics : just replace or/and adapt
No double or float, sqrt, cos, and trigo : fixed point reals, tables, limited developments etc
Solutions & Explanations :
I created a MathFixed class that does float operations and trigonometric on int's and sinus are stored in a table.
For info the 3D mesh was generated in java with a external mini3d toolbox,
Compute sequential rotations
This could be also run in an applet or application (just replace imports)
Using a Preprocessor in Java ? (H4x0r stuff)
Most of the code is the same between different sdk and api, To ensure genericity I use GNU cpp preprocessor to generate java file, Java Reflexion could solve this ugly method but can't be used in j2me.

If you familiar with C or C++ (or Povray) using a preprocessor, should not be a trouble for you. Else here are some basic sample code :

// file://~/MyCanva.java.in
#ifdef MIDP20
#define paintTriangle(g,a,b,c,col)  { \
     DirectGraphics dg = DirectUtils.getDirectGraphics(g); \
     dg.fillTriangle(a[0],a[1],b[0],b[1],c[0],c[1], 0xFF000000|col ); \
    }
#else //default
#define paintTriangle(g,a,b,c,col)  { \
        g.drawLine( a[0] , a[1] , b[0] , b[1] ); \
        g.drawLine( a[0] , a[1] , c[0] , c[1] ); \
        g.drawLine( c[0] , c[1] , b[0] , b[1] ); 
#endif

class MyCanvas { // ...
  protected void paint(Graphics myg) { paintTriangle(myg,mya,myb,myc,mycol); }
}
Then you need to "compile the file"
cpp -undef -fno-show-column -DMIDP20 -C -P -I. -I \
 < MyCanvas.java.in > MyCanva.java
And you'll get a new file where macro was replaced :
// file://~/MyCanva.java
class MyCanvas { // ...
  protected void paint(Graphics myg) { 
     DirectGraphics dg = DirectUtils.getDirectGraphics(myg); 
     dg.fillTriangle(mya[0],mya[1],myb[0],myb[1],myc[0],myc[1], \
           0xFF000000|mycol );
  }
}
Got the Idea ? It is pretty simple , but can really be obfuscated thats why Java designers removed this feature in the language.
Evolutions & Révolutions :
Store mesh in compressed stream not class, and make a parser because there is a 32Kb file class limit :
java.lang.OutOfMemoryError: Mesh: Maximum byte code length (32kB) exceeded
Compute combinated rotations with Quaternion
Check for Stability in Numerics
Re-implement 3D algos for hidden faces removal (Zsorting, Zbuffer, BSP etc)
Texture mapping and lightning etc
