Hello everyone, I took the current discussions about AI or no AI as an opportunity to actually let AI help me out for once. **The Situation:** - For years, I’ve been tinkering with an ELITE-like game. I introduced the current mockup here in the forum under Games. The 3D engine used in it is what I used in this demo (further below). - So far, I had only bothered to design and store cuboids (= space station in my mockup) or simple structures (= other spaceships in my mockup). Doing that with a sheet of paper is brutally tedious. Yes, CAD programs or Blender exist… but I wasn’t / am not quite there yet. - I had already pieced together the first few objects by hand. With ChatGPT, creating additional objects was fantastically easy. Does that make this demo objectionable? Here is my ChatGPT prompt: > Calculate the 3D coordinates (x,y,z) of a dodecahedron. Assume that the origin is positioned as close to the center as possible. Normalize the coordinates to a signed byte (i.e. from -128 to +127). > Each face of the dodecahedron can be represented using 3 triangles. Give me the triangles for each dodecahedron face. That is, their edges. > Use a notation that I can import into a Z80 assembler. That’s how all the other objects were created, with the exception of the 3-sided pyramid, 4-sided pyramid, and the cuboid. From the house onwards, the 3D coordinates were generated by ChatGPT. [lichtspiel\_14.dsk](https://forum.cpcwiki.eu/uploads/short-url/iZtOlO3qCPPxFZFpRjWS2VrU5if.dsk) (190,3 KB) (run"licht") **Notes:** - It feels like it takes a veeeery long time to load. - In the browser version, the lamp appears flickering. This is incorrect. Better use a local emulator or the original hardware. **Controls:** - Cursor UP = Accelerate the lamp in one direction. - Cursor DOWN = Accelerate the lamp in the other direction. - Cursor LEFT = Accelerate object rotation in one direction. - Cursor RIGHT = Accelerate object rotation in the other direction. - SPACE = Next object - M = Mode 0, 1, 2 The special thing about writing software on an old 8-bit computer is, after all: 1. pulling it off, and 2. coping with the system’s limitations. My first attempt for the demo was rendering a small sun with a spaceship. ![image](https://forum.cpcwiki.eu/uploads/default/original/2X/9/98a6b20a802ce58925bce5ca81c7745cd189feef.jpeg)(Sun = planet as well as spaceship taken 1:1 from the Elite mockup) Is this considered AI slop just because I had the coordinates generated externally? Hmmm… AI was super practical for generating the 3D coordinates and was super-duper-crazy fast! I don’t know if it’s capable of ruining my hobby / my passion for coding in Z80 assembly??? ---

Ooh I love the mode change! ---

Nice shading, many triangles, and smooth movement. > [@SoftDevil](#): > > Ist das nun KI-Slop, nur weil ich die Koordinaten extern habe erstellen lassen? Hmmm… Die KI war zum Erstellen der Raumkoordinaten nun sehr praktisch und ging ober-super-extrem-schnell! From my point of view this is not AI slop, because you only used the AI to help you with a detail, something you could as well have done on your own (and maybe even better for the less-mathematical, more real-world objects), but it would have been more time consuming. No one knows where the AI found (or copied) the objects from. So for this use case, I expect that at least the use of AI is made transparent. Sadly, the original ownership or copyright for the objects (although they are quite basic) is lost. ---

Unfortunately, the original ownership or copyrights to the objects (even though they are quite simple) are lost in the process. Thank you for your perspective. Thanks to your words, I feel more acceptance within myself to clearly label AI-generated content. I will now adhere to this more strictly in my professional life. THANK YOU!
