Well, as jsalonen (and I) said in the other forum, it involves some tricky stuff. You can either use clipping (check where the polygons collide with the viewpoint and 'clip' them, creating new polygons that can be drawn) or Z buffering, which produces the best quality but also needs extra memory, the size of the view screen actually. So z buffering sucks memory a lot. Then the easiest way is that you don't draw polygons that are too near you.

The easy solution, (not to draw at all) works fine for the "fligt simulator" with an open landscape. However, if I create a world where I move around in caves, the problem becomes too visible (does it have to be like that?). And cliping isnt that easy eather, bebcause I have not restricted the polygons to triangles...

Z buffering.

z buffering is not simple.

Well, actually it's not that difficult. Of course you need to make some modifications, but if you can handle the speed and memory requirements it gives the best quality.

Well. width zBuffering I would have to write my own fillPolygon routine. And I would have to draw on pixel level. And all the modifications that follow... And the speed would be a problem (after all this is an applet). - I am not looking for the correct solution. I am looking for a dirty cheap and ugly solution that makes my problem less visible!

Well, if you intend to do any shading you have to write your own fillPolygon routine anyway. Anyhow, I don't know of an easy solution to your problem...
