We now use multi-stage builds so that the build-time dependencies and code are not included in the final image. Also updated the README with information about Docker hub, and added a LICENSE file.
VirtualPlanetBuilder Terrain Generation for FlightGear
This repository provides a DockerFile that can generate an image to build VPB terrain. It is currently based on the following versions:
- Ubuntu 20.04 (LTS)
- GDAL 2.4
- OpenSceneGraph 3.6.5
- VirtualPlanetBuilder 1.0
The image is available on Docker Hub, so docker will download it automatically when it is requested for the first time.
Building terrain
The provided run_image.sh will launch a container and present a bash prompt with the environment for building all set up:
- GDAL and VPB executables will be available to run
- The
datadirectory will be mounted at/home/flightgear/data/inside the container (readonly) - The
outputdirectory will be mounted at/home/flightgear/outputinside the container with write access
A sample script in data/run.sh is provided to automatically build a small area around Edinburgh. To build the terrain:
- First download SRTM heightmap and CORINE landclass data (see the wiki for details: https://wiki.flightgear.org/Virtual_Planet_Builder and
data/run.shfor links) - Extract the files to
./data - Launch the container with
./run_image.sh - Run
./data/run.shat the prompt. The script will saves all output to the mounted./outputfolder, so its accessible outside the container.
A shorthand for steps 3-4 is also available:
./run_image.sh ./data/run.sh
Building Image locally
To build the image locally for debugging or contributing, run build_image.sh. This will build and tag the image with the name flightgear/ws30-vbp-generator:v1.
