Commentary on the closing keynote from RustConf 2018, which you can view here:
https://www.youtube.com/watch?v=aKLntZcp27M

Rant: Entity systems and the Rust borrow checker ... or something.

my 3d cellular automata simulation written in rust with multi threading was sub-optimal. Using benchmarks with criterion and the help from my community, I learnt what the bottlenecks of this application are.
Today I share the journey I went through to optimize my multi-threading code!
Let's talk about the code... ;)

Rust multi-threading code review

Graphics programming is so cool!
I managed to make a water shader, load 3d models, create a beautiful transition shader in just 7 days using OpenGL and the Rust programming language.

I used this OpenGL wrapper called glium:
https://github.com/glium/glium

I also utilized a game framework called macroquad:
https://github.com/not-fl3/macroquad

Water & Transition shader is open source on by github page! (wip)

I tried learning OpenGL in 7 days - using Rust

I remade my voxel game 3 times. Unity, Rust, Bevy.

☝️😀

I went from Unity, to pure Rust (no game engine), to then moving all my code into bevy (a Rust game engine).
The latest move, was promted due to having some project architecture challanges, that I felt could be solved easily with Bevy. Their entity component system is also one of the front runner in innovation I think, which is very exciting to work with.

Graphics rendering api: https://wgpu.rs/

multithreading: https://github.com/zesterer/lagoon
benchmarking: https://github.com/bheisler/criterion.rs
profiling: https://crates.io/crates/profiling, using Optick feature

My other game framework of choice: https://github.com/not-fl3/macroquad

I remade my voxel game 3 times, this is why

Graphics programming is freaking hard! Voxel engine, water/wind shaders, landscape height map generation, scene transitions, are just a few of the things I've made with it so far. If you want to build a car, it might help to reinvent the wheel sometimes to fully understand it on a deeper level.
All projects I've highlighted in this video was written with Rust + various libraries!
The water + landscape + wind project I made specifically for this video using Rust and wgpu.

It's hard to quantify but rest assured, I've spent more than 100 hours trying to learn this skill.

100 Hours Of Graphics Programming

I added Rust support for the Unity game engine.
Is it really possible? YES it is!
I managed to make a game 100% coded in Rust, but using Unity as editor and runtime.
This has to be one of my craziest projects yet!

I utilized a library called Bevy game framework/engine, to handle the gameplay programming. Utilizing Bevy systems I was able to hide the Foreign Function interfacing code from the gameplay code.

Have a nice day :)

Rust and Unity game development

I'm making a voxel game with the rust programming language and a game engine called bevy.
Hot reloadable rust code, ambient occlusion, physics, block texturing, dynamic camera, game design: damage formula for spells,
are among the things I've implemented the last 3 months.
The project is alive!

Voxel Game Development Is Hard

Time to LEVEL UP my graphics programming skills by making a Voxel Engine from scratch using the Rust programming language.

I've been considering remaking my Unity voxel rpg game using Rust, this is my first test to see if I'm capable of doing a 3D voxel rendering application.
I managed to implement voxel rendering, chunk management, flying camera and simple lightning. Future plans is to optimize the code, I have not done any benchmarks, but it does need some speed improvements.

This was made using wgpu-rs which is a wrapper over OpenGL, DirectX, Vulkan, Metal or WebGPU.

The voxel project is open source here!

A note on these videos, I think they do a great job in showing the realities of making a voxel engine, and at the same time providing good information on how it works.
