LIVE Interactive Visualization Environment for Computational Geometry

This project aims to create a system for interactive visualization of 

algorithms from computational geometry.

# Running the application

## Using gradle

You can run the main UI using gradle directly:

    ./gradlew run

## Using scripts

Setup the execution environment:

    ./gradlew createRuntime

Then you can run the main executables from the build directory:

    ./scripts/livecg-ui

    ./scripts/livecg-create-image

    ./scripts/livecg-visualization

## Using standalone JAR files

Build the JAR files:

    ./gradlew fatJars

Then run them like this:

    java -jar build/libs/livecg-ui.jar

    java -jar build/libs/livecg-create-image.jar

    java -jar build/libs/livecg-visualization.jar

# Setting up the development environment

You can create an Eclipse project like this:

    ./gradlew cleanEclipse eclipse

# Editor

## Key Bindings

### Main

File:

* `Ctrl + N`: New document

* `Ctrl + O`: Open document

* `Ctrl + S`: Save document

* `Ctrl + Q`: Quit

Tools:  

* `q`: select/move mode

* `w`: rotate mode

* `e`: scale mode

* `a`: rectangular selection mode

* `s`: add mode

* `d`: delete mode

Edit:

  

* `Ctrl + A`: Select all objects

* `Ctrl + Shift + A`: Select nothing

### Move mode

* `Ctrl`: while dragging nodes, snap to other nodes

### Add mode

* `left mouse button`: add a node

* `Ctrl + left mouse button`: close a ring

### With selected object

* `Ctrl + Shift + 'o'`: open / close a ring
