"geo-viewer" is being updated with improvements. It's a webapp and open source. w3reality.github.io/three-ge…
Rust implementation of Langton's Ant
Simulation from blank to emerging "ladder" at step ~ 10,000, which is explained by Numberphile youtube.com/watch?v=NWBToaXK…

Rust-wasm multithreading capability applied to wasm-demo of the 'plotters' crate (github.com/38/plotters) 🦀 📈.
In this demo, we are plotting a computationally heavy Mandelbrot Set while the main thread is busy with 3D cube rendering.

CA Simulator prototype (with core logic in Rust; GUI in JavaScript).
Rule switching demo:
Game of Life (en.wikipedia.org/wiki/Conway…)
-> Ulam–Warburton CA (en.wikipedia.org/wiki/Ulam%E…)
-> Langton's Ant (en.wikipedia.org/wiki/Langto…)
Developing a Rust crate for writing 2D cellular automata (CA). The idea is for devs to just implement `RuleTrait` to create a new CA.
For example, here's ~30 LoC Lanton's Ant (en.wikipedia.org/wiki/Langto…) working.

Prototyping WebM/HTTP streaming of framebuffer. Initially, using the Game of Life as test pattern generator
github.com/rustwasm/wasm_gam….
It seems, we can generalize it to be an education material on 2D cellular automata j-devel.github.io/demo/life/…
So plan to add more features & GUI.
In es-pack-js v0.5, added `--rustwasm` mode.
To transform wasm-pack generated artifacts into standalone umd/esm modules usable in browsers/Node.js:
$ wasm-pack build --target no-modules
$ es-pack build --rustwasm

Native @RIOT_OS running with #LVGL + SDL2
RIOT's LVGL sample is based on the `disp_dev_t` abstracted display. So for native development, tried implementing a custom one using the SDL2-based driver github.com/lvgl/lv_drivers/b… It works.
Reworked on API in three-geo v1.4.
Now, basically, a single line of async call is suffice to build a satellite-textured DEM ready to be rendered with three.js.

Started writing a firmware targeting #ESP32 IoT chips in Rust. Following an article dev.to/jeikabu/matrix-voice-… we've got a recursive `fib()` function demo working.

Write multithreaded web apps in Rust!
Published a suite of new crates that facilitate mutithreading in Rust and WebAssembly #rustlang
All listed examples are runnable in browser:

Testing a custom laser pointer in a WebXR-based VR app. Just refurbished our WebVR 1.1-based demos following the recent upgrades of the WebXR ecosystem:
- Chrome 79 w/ WebXR
- three.js r112 w/ `renderer.xr`
- WebXR emulator extension

Simple visualization of WebXR controller events (WIP).

There's an analogy between
- A Web client fetching data from multiple servers,
- A JavaScript main thread delegating jobs to worker threads.
Both are `async`, and fit well into the `mpsc` model.

The same concept would also apply to
- A process running Docker commands
We've found this talk youtube.com/watch?v=CMB6AlE1… pretty effectively telling about the dawn of a new type of computing with Rust and WebAssembly being a key enabler.
Managed to have control of Wasm binaries (either compiled by Emscripten or `wasm-pack`) running in Web Workers. The Web Worker API has been around us since almost a decade ago. We'd think this matured API is yet invaluable in these 'modern' use cases.

We've made a webm/mp4 encoder inspired by "Running FFMPEG with WASM in a Web Worker" paul.kinlan.me/running-ffmpe… One limitation is FFmpeg itself runs in its single thread mode so it's not as fast as desktop command😂

Implement a convenient geo method `(lat, lng) => [x, y, z]`, where `[x, y, z]` is a point in terrain coordinates, and `z` is its elevation! Basically, raycast to the triangulated (i.e. interpolated 😀) DEM in world coords (blue) and measure results in terrain coords (red).

VR app (rust-canvas-juliaset) that can interactively compute&visualize the Julia set on a planar object. Here, have we ported wasm-bindgen's (github.com/rustwasm/wasm-bin…) julia_set example written entirely in Rust🦀

source code: github.com/w3reality/threele…
We've found that, using wasm-bindgen, developing WebVR apps powered by Rust code becomes pretty seamless. We've made a template hello app showing exactly how to do it.

Demo of "lenet-aframe" where we encapsulated the TensorSpace LeNet model as an A-Frame component. (experimental - no UI components for char input; ML stuff works fine programmatically though)

How to arrange productivity in VR? Experimenting with VR apps where the user can indeed gain some practical value (e.g. learning) in 3D space. In this VR-based ML app, that value is expected to be educational.

Prototype of the glTF model selection panel. Using models originally in Sketchfab (kudos to creators😀) that we statically hosted. Super interesting if we can dynamically query and render them by Sketchfab API.

Crafting a VR paint app for creativity. Soon implementing VR-controller binding stuff for painting. Should be quick 😇 since mouse to WebGL canvas interaction is already done as in video. Live demo (WIP): w3reality.github.io/threelet…
