Test : Free 3D Engine Demo for Mobiles @ http://rzr.online.fr/java.htm

Oldskewl 3D Engine Demo
Oldskewl Free 3D Engine Demo for Mobiles : 100% pure software 3d renderer created on 1st gen of java compatible phones
I made up a [[3D]] engine demo midlet, maybe you'll be insteressed in testing it,
It is supported in most [[Mobile]] devices
( [[Java]]/[[J2ME]] : midp-1.0, midp-2.0, nokia, exen, palmos, imode...)
and web applet.
But it must be also tested while I am improving it (i can only test on emus).
Here are the links :
OTA,WAP,GPRS : (install app to the phone)
http://37337.free.fr  or http://rzr.free.fr/wap.wml
WWW : (get .jar + .jad for your phone)
http://rzr.online.fr/java.htm
Contact me online if possible :

I expect that to publish a SDK in the future, for users that want to disign some simple 3D puzzles games (like rubic's cube etc)

DEVELOPPER

Current API (prerelease version) http://rzr.online.fr/tmp/doc-api-midp1_0/

Wanna contribute, leave some notes on the wiki diet3d page : http://rzr.online.fr/q/Diet3D

MISC INFOS

Several pple did ask for access to use diet3d to display their 3D model currently this feature must requier some addition to my code which requiere a bit of time i may look at this before 1st of june 2004, unless some pple make a parser

As long there are no decent parser ready, I can help to give a demo version which will include your models all object must be sized (2*11585) ^ 3

here are 2 exemples of models (1st one is cube , 2d one is the pinguin),

… I will also made a converter :

http://who.is.free.fr/wiki/index.php?Mini3D for linux : http://rzr.online.fr/tmp/mini3dconvert

May it helps (stay in touch in the rzr-en list)

[[ToDo]] /

Data Specs

/// vertices (scaled between - 11585 and + 11585
public static final int mesh_vv[[]][[]]= {
{ 0, 11585, 0 }, ...
};
/// faces (triangles of vertices index)
public static final int mesh_vf[[]][[]]= {
{ 56, 48, 47 },  ...
};
/// color per face (0xRRGGBB )
public static final int mesh_vc[[]]= {
0xed80ed,  ...
};

If needed, I made a tool for converting | seek for mini3d

[[ToDo]] / Rubiks version

class Rubiks {
int[[]] vertex;
int[[]] faces;
int[[]] colors;
// change the colors
public void rotateFrontRow( int rownum , bool rightOrLeft) {}
}

I done for a 2x2x2 cube, now replace vertex and faces array by 1D arrays , will optimise speed.

PARSER

simple file parser (in java using j2me API) input file format maybe anything as soon as Mesh are described as list of vertex (int , int , int) and triangles (int, int, int) … vertex should be int because we are using Fixed Points maths

PDA

palmos4+ : pick the .prc file in the (midp-1.0 & 2.0 folders)

http://rzr.online.fr/docs/java/diet3d/

and use sun J2ME JVM for palm (I can convert .jar file for other jvm on

demand, just tell me how)

midp1.0 has been tested successfully on :
  • Palm / I TungstenT2 + Sun JVM (midp1.0)
  • Palm m515 (Palm OS 4.1 + java HQ 1.0) (midp1.0) @ http://bdav.net

Does not work :

  • <ekido> m341i , mitsubishi imode

portalmmm/2.0 M342i(c10;TB)

SIE-MC60/10 Profile/MIDP-1.0 Configuration/CLDC-1.0 UP.Browser/6.1.0.7.3 (GUI) MMP/1.0 UP.Link/1.1

Thanx to BetaTesters see Mobiles :

<alkama> it's a mitsubishi m342i
<alkama> it has some imode j2me (doja1,5)
<RzR_amilo> the doja version is at http://37337.free.fr
<alkama> 404 on the jam
<alkama> hum, java.lang.ArrayIndexOutOfBoundsException
<alkama> on the 8th effect
<alkama> oh, and you realy should think about locking the graphics
<alkama> for each frame
<alkama> looks like you're not locking the graphics, it makes the screen shiver;)
<alkama> bad refresh;)
<alkama> except that, it's fine
