3ds loader: null pointer in SmoothGroupProcessor

[zzorn]

Hi,

I'm using the latest xith-3ds loader available from the xith toolkit projects download page.  Loading some models seem to cause a null pointer exception in the class org.newdawn.xith3d.threeds.SmoothGroupProcessor, in method calculateSurfaces at row 160:

1   2   3

159:        for (int i=0;i<normalCache.length;i++) { 160:            normalCache[i].normalize(); 161:        }

The Jeep model loads fine, but some other 3ds files cause that exception (they all seem to use smoothed / gouraud shaded surfaces, in case that has anything to do with the error).  I don't have access to ftp upload at the moment, but can send the model by mail if needed.

Traceback:

1   2   3   4   5   6   7

java.lang.NullPointerException       at org.newdawn.xith3d.threeds.SmoothGroupProcessor.calculateSurfaces(SmoothGroupProcessor.java:160)       at org.newdawn.xith3d.threeds.SmoothGroupProcessor.process(SmoothGroupProcessor.java:64)       at org.newdawn.xith3d.threeds.TDSLoader.processChunk(TDSLoader.java:132)       at org.newdawn.xith3d.threeds.TDSLoader.load(TDSLoader.java:99)       at org.worldforge.gamesystem.shape.Model3DSShapeFactoryLoader.loadShapeFactory(Model3DSShapeFactoryLoader.java:90) ...

Best regards,

Have you got the latest version of the loader, I think we've done this one already.

If not, feel free to send the models over to me and I'll try and take a look in the near future.

As a work around you might try flipping the flag for indexed geometry when you load.

I was using the xith-3ds-1 version from the xith tools download page earlier, but switched to the xith-3ds-2 version from the newdawn homepage now.  However, it seems the same problem is still persisting.  

I'm sending the model that is causing the exception to you Kev.
