Have you ever spent all day with ChatGPT?  Have you ever spent all day with ChatGPT and<\/em> Gemini while hyper-focused on getting them both to code and create looping noise shaders in Open Shading Language?<\/p>\n

This has been quite a learning day, from noticing the personality quirks in A.I. to learning about coding shaders to kind of starting to understand why looping noise is so hard to achieve through code.  The animation is now using two OSL noise shaders that ChatGPT and Gemini each coded.  Specifically, the noise shader that ChatGPT created is inside the noise shader that Gemini created.<\/p>\n

Like I thought, the noise that ChatGPT created just ping-pongs back and forth which is a cheap ass way to make a loop.  But the math behind the scenes is doing the best it can to make that transition not so apparent, so still a good job.<\/p>\n

Then Gemini after much finagling and tweaking finally explained to me that getting a loop the way ChatGPT was doing it was always going to result in a ping-pong effect, it’s just inherent to how the math generates the noise.  Gemini then went a step further and suggested another method to get looping noise could be by using cylindrical UVW mapping and then animating the coordinates around a circle.  Um.  Ok, I said.  Do it.  It did.  It worked.  It’s really simple, it just moves the generated noise texture around in a circular pattern and on its own it’s not very impressive, but when you start combining motions things can get interesting quickly.<\/p>\n

And again Gemini went a step further and offered more unsolicited advice on how to break up the admitted monotony of its circular animation method.  It started suggesting to add distortions to the noise.  Um.  Ok, I said.  Do it.  It did.  It worked.<\/p>\n

The code has tripled in size from where I left off yesterday and there’s been so much information overload and tweaking to the shaders today that I’m not even sure what exactly they’re doing at this point.  But they’re both working and they’ll be incredibly valuable tools to have.<\/p>\n
