This is a port of an simple raytracer that I wrote in c++/cuda for an university project to Rust in order to learn it.
It reads a simple scene files that let you specify very simple geometries like spheres, planes and also to import wavefront obj file. (Some examples below)
I also handled simple multithreading (with rayon) and model trasformations (that aren't present in the original implementation)
In order to run the game, first clone the repository and enter the folder:
git clone https://github.com/colobrodo/raytracer-rs.git
cd raytracer
Then run the Rust compiler:
cargo run
Voilà 🎉
Simple usage:
cargo run .\scene\simple_sphere.scene -o .\img\simple_sphere.bmp -s 1
You need a scene file as first argument (mandatory).
With the -o or --output option you can specify where to save the generated image.
Using --sample-rate or -s you can choose how many rays use per pixel (20 by default)
Here some of the generated images
size 1200 1200
sphere (0, 0, -3.0) 1 white
plane (0, 0, 1.0) -6 white
# light sources
light (-2, 0, -3) blue
light (0, -2, -3) red
light (2, 0, -3) green
light (0, 2, -3) yellow
size 1200 1200
model "./models/bunny_lp.obj" white > scale 0.4 > translate (0, 0, -7)
# light sources
light (0, 1, -2) blue
light (0, 0, -1) green
- I plan to use octree or grids to optimize the (now very slow) mesh rendering
- If I reach reasonable time with Octree/Grid optimization, try render a video rendering each frame and then using ffmpeg
