Tinyraytracer on ESP32

Hello and thanks for this génialissime project 👍
Just to let you know I tried your code on ESP32 and it worked just fine with very little modification.
The ESP32 doesn't have that much ram so I applied a direct TFT rendering approach instead of using the framebuffer.
Rad! Pocket RayTracer! How long to render a frame on the TFT?! I would legit love to have a keychain device that raytraces :D
Wow, that's very cool, thank you!
I'll add a timer to the code when back from work, but it takes about 20 seconds to render.
It's far from being able to render an amiga boing ball animation in real time, but still impressive for a 240MHz MCU :-)
ESP + OLED, binary image with simple test if the color is >128.
1.5s for the 64 x 128 screen size.
looks like a LoRa Heltec build ^_^
interesting how that ssd1306 seems to have burn traces from its usual duty, I always thought this would never happen on OLEDs.
do you have an estimation of its total uptime ? I haven't observed this yet but I guess it's time to add dimming to my own ssd1306 projects
3 weeks of constant uptime. Now with dithering :)
I wish this OLED was capable of doing stable grayscales
*currently testing multiple image rendering to sdcard as jpeg data, I've modified this jpeg library so it uses the psram
the ambition behind this is obviously to play a pre-rendered animation although I'm not sure yet jpeg is the right choice to achieve a fast frame rate when playing later (GIF compression is less efficient but supports transparency+partial writes)
Fantastic. Can't wait for my display to arrive :)
getting closer to the Amiga Boing ball sphere material, playing a 2D animation over it just because ...
Awesome!
I'll just put this here as it somehow seems relevant 🤣
