• @Krusty: Sorry, I never realized you were talking about the file structure and not just the fact I didn't hide the catalogue. Though, I find the "crimes" I committed with files are not so extraordinary. Maybe we should discuss this in an email so that we don't polute this thread though.

  Optimus: It looks a bit like you are offsetting the rays by the cosine of the ray angle in order to counter the fisheye effect. Do you have a regular step in angle between pixel columns? If so, this is incorrect. You should be either using the tangent of the ray angle or a linear transform.... Probably difficult on the ZX!

  
  
  Yep, that's exactly what I did I think, what you say in the first sentence. Another possible reason was, the pixel resolution has twice wide pixel, then my column renderer draws a byte which is two pixels packed, and when I tried the cosine method from my PC raytracer I got a wrong result, maybe because I have to compensate for the ratio? (though, I am not sure). So then I compensated by multiplying a factor x2 to the cosine fishbowl correction data which also still didn't made it and found a value that was almost good. Your other suggestions are interesting too, thanks!

• The original argument was about hiding the data files. It wasn't about the number of files. Now, the argument has transfered to this and I don't even understand why. The thing is, it would be worthy to argue about this if I had for example 8 or 10 small files and the loading was really long, but I think I have packed most of the stuff in quite a fewer numer of files. There is a big file with code and data packed together in 24kb iirc (the maximum possible might be 32kb I think) and a loader file (wolf.bin) with some more data packed together that it was easier to fit there but they are together and not scattered in separate files, and only the two runseq 10kb each files that maybe could be fused together in a single one but it was easier this way the way I relocated stuff in extra memory in the loader. But this is what I have, it's one big code-data file, two additional data-files and the loader packed with other remaining data of last resort. I thought structure-wise the files were quite ok. I had 4, it could be at best 3 and things are quite fused together.
  
  The thing is that this discussion has started with Krusty's mention of not hiding my files and went on to the claim that my file structure is horrible which is not the case and it would never happened we had the catart in the very first beggining and hell knows what I would find if I had seen the contents of other popular CPC demos with a viewer.
  
  I am not sad about it, I am just puzzled. If I released the same demo on the C64 nobody would care about these things.

• @fizzer: I do apply for fisheye distortion but it's just not perfect. I am not sure why. And, there is a process which might make it loose more precision and one can see the walls are not perfectly straight when looking directly vertically at them but there are little inaccuracies, which is something I am willing to research further when I use this engine for a future project (game probably).

• New version added, with simple catart and hidden files, for the convenience of your CPC cultural rules :)

• I didn't found it relevant (maybe the CPC scene does?). Great demos are released on PC and all the files are there. Does it make any demo worse?

• Quite nice. Some blocky attribute parts (but it's funny to see a triangle rasterizer in such low res :) and a finaly part with the high res tunnel renderer which I liked quite.

• Wow, quite good for a debut. Big screens with some really smooth effect, plasmas, rotozoomer and twisting bars. Makes me wanna start coding my next 8bit demo for Speccy :)
