A raytracer in aarch64 assembly, following the tutorials by Peter Shirley, Trevor David Black and Steve Hollasch.
At the moment the first book of the series is done, and the result looks like this (using an output size of 800x450, 400 samples per pixel and a maximum depth of 50):
To adjust the image dimensions and rendering setting, you can edit the relevant parts in the .rodata section of main.s. The scene itself is setup in world.inc.
I am just starting out with ARM assembly, so I can't give any guarantees that the code will work as is on your device. But it compiles and runs fine on my Pi 5 (using Pi OS Trixie) by running the following lines:
make
./aarch64ray
If you have ImageMagick installed, you can easily convert the resulting PPM image to PNG by running
magick image.ppm image.png
