rust-image-generation

🦀🦀🦀 This is pretty much a log of my Rust-learning journey ! As a beginner rustacean, these are my two first projects : 🦀🦀🦀

Julia sets :

Generating representations of Julia sets for a given complex number

Here i used the "image" and "num_complex" crates to create this bin project :

In a bash terminal (w/ julia binary in working directory) usage may look like :

$ ./julia <real_part> <complex_part> <image_size_in_pixels> <nb_of_shades> <img_name_with_extension>

ex : ./julia 0.2 -0.6 2000 300 julia1.png

NB: numbers are stored over 32 bits, large numbers may cause unwanted behaviour

The only format i've tested is png, jpeg should work according to documentation

Making Gif files

You can also make a gif from several images automatically with keyword "animate" : doing so creates an animation that starts from the given number and shows Julia sets for a whole rotation around point 0, in as many steps as you like !

$ ./julia animate <real_part> <complex_part> <image_size_in_pixels> <nb_of_frames>

Faster !

Want to see individual frames of your animation ? Encoding gifs takes a while with the image crate. A faster alternative is to generate infividual frames with the "frames" keyword :

$ ./julia animate <real_part> <complex_part> <image_size_in_pixels> <nb_of_frames> <path_to_frames> <format>

Colorscale

I quickly got frustrated with (for my purposes) complicated crates for handling color. Thus, i made my own gradient calculator library, taylored for my needs : it spits out a Vec of any amount of colors, linearly switching between as many colors as you want.

Raytracer :

My second rust project was a simple raytracer : This also uses the image crate, and was built in a Test Driven Development approach, to familiarize with rust's test system.

Thanks for checking out my projects !
