This has been reported here. Unfortunately I never get this kind of crash. So it would be very helpful, if you could send me a testcase, where this happens.

I don't know the reason but this works:

Code:

if (isShadow){
    for (int i=0;i<shapes.size();i++){
        Appearance app = shapes.get(i).getAppearance();
        Material mat = app.getMaterial();
        mat.setAmbientColor(Colorf.BLACK);
        mat.setDiffuseColor(Colorf.BLACK);
        mat.setSpecularColor(Colorf.BLACK);
        mat.setEmissiveColor(Colorf.BLACK);
    }
}else{
// init transparency
    TransparencyAttributes transparencyAttrs = new TransparencyAttributes(
    TransparencyAttributes.BLENDED, 0f,TransparencyAttributes.BLEND_ONE,
    TransparencyAttributes.BLEND_SRC_ALPHA);

    ColoringAttributes colorAttr = new ColoringAttributes();
    colorAttr.setShadeModel(ColoringAttributes.NICEST);

    for (int i=0;i<shapes.size();i++){
        Shape3D shape = shapes.get(i);
        Appearance app = shape.getAppearance();
        if (shape.getName().endsWith("_transparent")){
            app.setTransparencyAttributes(transparencyAttrs);
        }
        Material mat = app.getMaterial();
        mat.setShininess(100);
        mat.setLightingEnabled(true);   
        mat.setSpecularColor(new Colorf(1.0f,1.0f,1.0f));
    }
}

and this doesn't work (unfortunatly I can't highlight the changes with a color in the code)

Code:

if (isShadow){
    Texture texture = null;
    PolygonAttributes polyAttrs = new PolygonAttributes(PolygonAttributes.CULL_BACK);
    for (int i=0;i<shapes.size();i++){
        Appearance app = shapes.get(i).getAppearance();
        app.setTexture(texture);
        app.setPolygonAttributes(polyAttrs);       
        Material mat = app.getMaterial();
        mat.setAmbientColor(Colorf.BLACK);
        mat.setDiffuseColor(Colorf.BLACK);
        mat.setSpecularColor(Colorf.BLACK);
        mat.setEmissiveColor(Colorf.BLACK);
    }
}else{
    // init transparency
    TransparencyAttributes transparencyAttrs = new TransparencyAttributes(
        TransparencyAttributes.BLENDED,0f,                            TransparencyAttributes.BLEND_ONE,                 TransparencyAttributes.BLEND_SRC_ALPHA);

    ColoringAttributes colorAttr = new ColoringAttributes();
colorAttr.setShadeModel(ColoringAttributes.NICEST);

    TextureAttributes textureAttr = new TextureAttributes();
textureAttr.setTextureMode(TextureAttributes.MODULATE);
textureAttr.setPerspectiveCorrectionMode(TextureAttributes.NICEST);

    for (int i=0;i<shapes.size();i++){
        Shape3D shape = shapes.get(i);
        Appearance app = shape.getAppearance();
        if (shape.getName().endsWith("_transparent")){
            app.setTransparencyAttributes(transparencyAttrs);
        }
        Material mat = app.getMaterial();
        mat.setShininess(100);
        mat.setLightingEnabled(true);   
        mat.setSpecularColor(new Colorf(1.0f,1.0f,1.0f));
        app.setTextureAttributes(textureAttr);
    }
}

[Marvin Fröhlich]

Are you trying to use Xith's shadowing system? Or are you using your own one? If you're using your own, how do you do it? If you're using Xith's shadows, don't do this for now. It is broken.

I would guess, that the crash depends on setting a texture/TextureAttributes or not, since this is what I changed right before these problems had been reported. Could you please try, if just commenting out the texture stuff "enables/disables" the crash?

Marvin

[mhermann]

Yes it enables/disables the crash

[Marvin Fröhlich]

Since you know, that I don't get the crash in the testcases, it would ge cool, if you could post a more complete testcase, where you get this crash. I mean, the two codings above are quite different. Maybe you could just modify one of the xith-tk testcases to reproduce the crash.

Marvin

[Marvin Fröhlich]

The problem should be fixed now. (see here).
