EtherDream Graphical Emulator

This is a visual emulator for the EtherDream laser projector DAC. It displays the points that are projected in real time, making it easy for development and debugging without actual laser hardware present.

This is currently in a working state and can be used for active EtherDream / laser projection development.

Installation and Use

Install Rust version 1.13 or greater.

For Windows - tested under MSYS2 environment. Install freetype in MSYS2 with: pacman -S mingw-w64-x86_64-freetype or pacman -S mingw-w64-i686-freetype. More info here.

git clone https://github.com/echelon/etherdream-emulator.git
cd etherdream-emulator
cargo run

Or to compile and run the release version (faster and more performant),

cargo build --release
./target/release/etherdream-emulator

The emulator sends EtherDream broadcast packets and listens on the default EtherDream port. Simply start sending traffic to it!

Rust laser projection projects:

• etherdream.rs, a Rust library for driving EtherDream.

• ILDA.rs, a Rust parser for the ILDA laser display format.

There are also a number of existing programs I've written that talk in EtherDream, all of which can be "emulated" with this software:

• Laser Asteroids, an EtherDream laser projector video game I wrote in Python for the Fall 2012 SPSU Game Jam.

• Laser Pong, another EtherDream video game I wrote in Python during Summer 2013.

• Untitled Game, written for two laser projectors (and two EtherDream DACs) by myself and Scott Adams for the Fall 2013 SPSU Game Jam. It's quirky, but demonstrates multi-projection. Scott worked on the game while I worked on the network and graphics stack.

• Laser Testbed, which contains lots of my early testing with laser projection. There are dozens of animations, shapes, primitives, etc.

• Laser Client, which projects slides containing GML (Graffiti Markup Language) and poorly serialized SVG objects, which can be individually programmed with animation and 2D transformations. (The code is terrible.)

TODO

There are a number of future improvements to make:

• Add a gif or screenshot.
• Full protocol support (all commands, plus a better state machine)
• Unit tests
• Better error handling
• Better logging
• Support Multiprojection (multiple DACs/projectors)
• Draw on a 3D surface and calculate projection angles and deformations
