LiveCG

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
