Hi everyone,

first let me congratulate you for the amazing work done on xith3d, it is very impressive.

I am trying to load an official Quake 3 BSP map (q3dm13.bsp). i first used the 0.9.6 beta 1 build available on the website ; it worked fine except for the TGA textures which Java tried to load as WBMP file :

java.lang.IllegalArgumentException: Empty region!
   at javax.imageio.ImageReader.computeRegions(Unknown Source)
   at com.sun.imageio.plugins.wbmp.WBMPImageReader.read(Unknown Source)

   at auberge_emu.a.<init>(Unknown Source)
   at auberge_emu.MainApplet.run(Unknown Source)
   at java.lang.Thread.run(Unknown Source)

You can see the applet showing this exception in the console for each TGA texture here (JPG textures are loading ok) : http://agrv.free.fr/auberge_emu_xith

So I fetched the latest svn, adapted my code to the new InputSystem and tried it again. This time, the map will not display, instead I get an "/ by zero" exception :

java.lang.ArithmeticException: / by zero

You can see the applet with this version here (exception showing in the console) :

Could you please help me on this matter ?

Could you possibly send me this .bsp file?

It is in the http://agrv.free.fr/auberge_emu_xith/auberge_emu-data.jar file, along with all the textures.

I have fixed those bugs. Please update from SVN.

btw. Do you have a parser/loader for the Q3 shader files? If you do, would you mind sharing the code? And do you handle the map's billboards in some way?

I cannot test the fix because the svn trunk does not compile ; it seems that the jagatoo.jar is missing some classes in the org.jagatoo.loaders.models._util package. Or maybe I am missing something...

EDIT : ok, I managed to build a jagatoo.jar archive from the jagatoo svn to build the xith3d.jar and test my app, now the bsp file is loading without error. The TGA textures are also displayed.

For the billboards and the shaders, that's the point where I stopped my own bsp loader and tried the one in xith3d ; but I am willing to check this out and of course will share the code if i come up with something interesting.

Anyway, thanks for this quick fix and don't forget to update the jagatoo.jar in the xith3d svn.

Hi, I had to suspend my xith3d project for a few weeks and tried to run it with the latest SVN this morning. I am getting a new NullPointerException while loading the BSP file :

This happens also in the BSP loader test from the xith-tk SVN (just replace the resource at line 318 from BSPLoaderTest.java with "quake3/q3dm13/q3dm13.bsp", the files are still in the repository). Thanks for your help !

[Marvin Fröhlich]

Fixed.

Great, thanks !
