AMAPVox is an R package that embeds a Java Desktop Application. The Java part
of AMAPVox is distributed as a set of JAR files (Java Archives) and is not 
included by default in the R package to keep it light. The R package handles
the download of the JARs and manages multiple versions for the end user.

## System requirements

**Operating system**: Windows (7 or above), Linux-based, Mac OS X. 64-Bit.

**Java**: For AMAPVox v2 or above, Java is embedded with AMAPVox binaries. For
AMAPVox v1 the system requires Java 1.8 64-Bit with JavaFX. In practice either
[Java 1.8 64-Bit Oracle](https://java.com/download/) or
[Java 1.8 64-Bit Corretto](https://aws.amazon.com/fr/corretto/).

**CPU**: one required but multi-core CPU recommended for multithreading execution.

**RAM**: 1GB is enough for running the sample case. It will greatly depends on
the dimension of the voxel space and the size of the LiDAR scans.

**OpenGL**: Version 3 or higher, for visualization only.
