Barebones raytracing implementation in Arduino C++.
Some code was adapted from https://github.com/caosdoar/arduino-raytracer/.
This specific example is intended to run on the Sparkfun Microview Module, but you can easily adapt it to use a display of your choice for output.
- Vector math implementation including world <-> local space transformations for the shading frame
- Basic diffuse material with cosine weighted sampling
- Adjustable resolution, bounces, samples
If you want to use a different screen, replace #include <Microview.h> with your library of choice and update the functions below:
void setup() {
// REPLACE THIS TO USE A DIFFERENT SCREEN
uView.begin();
uView.clear(PAGE);
}
void drawPixel(int x, int y) {
// REPLACE THIS TO USE A DIFFERENT SCREEN
uView.pixel(x, y); // Screen drawing logic goes here
}
