-
-[**📚 Read this template tutorial! 📚**][template-docs]
-
-This template is designed for compiling Rust libraries into WebAssembly and
-publishing the resulting package to NPM.
-
-Be sure to check out [other `wasm-pack` tutorials online][tutorials] for other
-templates and usages of `wasm-pack`.

-## 🔋 Batteries Included
-
-* [`wasm-bindgen`](https://github.com/rustwasm/wasm-bindgen) for communicating
- between WebAssembly and JavaScript.
-* [`console_error_panic_hook`](https://github.com/rustwasm/console_error_panic_hook)
- for logging panic messages to the developer console.
-* [`wee_alloc`](https://github.com/rustwasm/wee_alloc), an allocator optimized
- for small code size.
-# Rust playground
-
-Things I have recently done while learning the Rust programming language.
+A rust library for manipulating and display of 3D objects on a canvas.
## Synopsis
-Change in one of the toplevel subdirectories and try `cargo build` or
-`cargo run`. Maybe not everything is working oob. Feel free to fix whatever
-you want.
+`cargo build`
## Description
-Various small examples I have tried while learning rust. The biggest and
-currently most active project is **fractional** which started as an
-implamentation of a rational number data type and then switched to a 3D
-math playground visualizing using **XCB** (in future it might also use
-a **HTML5 Canvas** for drawing as WebAssembly application.
-Using fractions with 3D math has several drawbacks:
-
-1. A huge part of 3D math is non rational, like sin, cos, tan and sqrt.
-2. The numerator and denominator tend to become very huge while nearing to non
- rational numbers and reduction is difficult and time consuming.
-3. Because of 2 it is way slower than the floating point calculation (at least
- with a decent coprocessor).
-
-Anyway, implementing the vector math stuff for both fractions and floating
-point was a nice playground for generics and traits. In future I might add
-another data type which implements the math as done by David Braben for the
-elite computer game.
+A 3D math playground visualizing on a canvas trait which the user needs to
+implement e.g. using **XCB** or a **HTML5 Canvas** for drawing as WebAssembly
+application. (Both exists in separate projects.)
## Requirements
-### Always
-
- A recent version of the Rust programming language as well as tooling.
Currently I use Rust 1.39.0.
-### For fractional
-
-- A running X Server with **XCB** and **X11-SHM** extentions
-
## Dependencies
-...
+- lazy_static v1.4.0
