# JCSG-MeshExtensions
[  ](https://bintray.com/miho/JCSG/JCSG-MeshExtensions/_latestVersion)
[JCSG](https://github.com/miho/JCSG) extension library for producing high-quality meshes from [JCSG](https://github.com/miho/JCSG) mesh objects. The mesh optimization is performed with the cross-platform meshing software [ProMesh](http://promesh3d.com/) which is available as [ug4](https://github.com/UG4/ugcore) plugin.
## Sample Code
```java
// we use cube and sphere as base geometries
CSG cube = new Cube(2).toCSG();
CSG sphere = new Sphere(1.25).toCSG();
// compute difference between cube and sphere
CSG cubeMinusSphere = cube.difference(sphere);
// create a copy of cube-sphere that shall be optimized
CSG optimized = cubeMinusSphere.
transformed(Transform.unity().translateX(3));
// perform the optimization
CSG all = MeshTools.optimize(
optimized, // csg object to optimize
1e-6, // tolerance
1e-4, // max tolerance
0.25, // min edge length
1.5 // max edge length
);
// save optimized mesh as "all.stl"
Files.write(Paths.get("all.stl"), all.toStlString().getBytes());
```
## How to Build JCSG-MeshExtensions
### Requirements
- Java >= 1.8
- Internet connection (dependencies are downloaded automatically)
- IDE: [Gradle](http://www.gradle.org/) Plugin (not necessary for command line usage)
### IDE
Open the `JCSG-MeshExtensions` [Gradle](http://www.gradle.org/) project in your favourite IDE (tested with NetBeans 8.2) and build it
by calling the `assemble` task.
### Command Line
Navigate to the [Gradle](http://www.gradle.org/) project (e.g., `path/to/JCSG-MeshExtensions`) and enter the following command
#### Bash (Linux/OS X/Cygwin/other Unix-like shell)
bash gradlew assemble
#### Windows (CMD)
gradlew assemble
