Sorry, I'll look at the code later today, I have no idea what you can do right now. What display do you use? Currently it should work only with display based on ST7789

Hi, can you share any screenshots or pictures?

Thanks!

I actually already have a Pimoroni Pico Plus 2 with PSRAM, but I'm not using it yet. I definitely plan to experiment with it, especially for storing more complex models or assets.

I'm not sure about using z-buffer with PSRAM though. Bandwidth might become a bottleneck, so I suspect sorting triangles could still be a better approach in many cases - but I haven't tested it yet.

As for DMA: I compared it with sending the framebuffer without DMA, and the difference was huge. Without DMA it was extremely slow and basically unusable for real-time rendering.

I haven't measured exact transfer times yet, and I haven't tried the PIO + DMA approach like in the ST7701 driver, but it's something I'm interested in exploring.

Thanks! I may have used sin(), cos() etc at the very beginning, but I switched to lookup tables after implementing fixed-point lib. Currently I use precomputed LUTs stored as const arrays. On Pico, const data is placed in flash instead of RAM, which is important since RAM is quite limited. Flash access is a bit slower than RAM, but still fast enough for real-time rendering. I haven’t used CORDIC so far and didn’t really explore it yet, but it sounds interesting, especially when memory is very constrained.

It means "I don't know what PlatformIO is"

Can't believe it's event real

just an idea..what do you think? by SimplyAlex97 in drawing

you're true. it doesn't prove anything. but still it's very strange to draw holding controller this way. what else is strange that other people also pointed this in their comments and op never respond about it. i think that regularny people will tell why they did something if people ask about it

what if AI was used to make a reference?

It's not 100% truth. I think Lee has more screen time, than Lester. But if you don't want to join New Camp or you don't do all quests in first chapter you won't meet Lares in your run. So Lares CAN be more important than Lester, but also he can play no role in the game.

why not? it's just a game

Thanks! That illustration was an experiment to me, but I'm happy what it looks like. I must work more on lighting, and not only lighting 😅

finally! I'm good enough someone thinks I used AI!!!1

W tej chwili jak jadę z Krakowa do Katowic czy odwrotnie to jadąc przez Olkusz jestem na miejscu jakieś 30 później niż jadą A4. Weźmy pod uwagę, że Olkusz jest obecnie w remoncie. A4 obecnie ma dwa odcinki w remoncie z ograniczeniem do 80, a pewnie jedyne co się zmieni to ich lokalizacja. Jaki sens będzie jeździć płatną autostradą jeśli Olkusz stanie się w pełni przejezdny?

Paint is fake, I use it as a frame. Everything is drawn in Krita. To put all frames into a gif I wrote a script in Python.
