1. Find better name for Baufenster

2. Group of parcels in same Baufenster: specify whether buildings must touch or keep a minimum distance

• finish one and double sided cuboid objects for attached building style
• adapt the moves for these cuboids
• compile reference lines
• instanciate building for each case
• BAUWEISE:
• g => buildings have to touch
• otherwise
  • building law for the area:
    • min(3m, height/2)?
  • minimum distance defined in state building law: building height (without roof) * 0.4, though at least 3m. if the roof slope is below 70° its height counts for 1/3, if the slope is above 70° its full height is added to the building height. but, baufenster trumps minimum distances! (declared in zoning plan)

3. Automatize construction of property units - splitting into simulation areas by plan part

4. Roof shapes

• if gable roof => modify FSI computation. roof slope is written in the legend to the plan. f ex 30-40°
• export building with roof
• ridge direction (not specified in plan) => we take the largest building in the fenster as a reference for the roofs orientation
• roofs count in the FAR calculation where a floor is defined as an inhabitable floor above the ground with a minimum height of 2.3m

5. How to differentiate between exact and maximum floors allowed

Running the simulator

mvn exec:java

Export the results to citygml Be careful of the directory where the j3dcore-ogl library is. Here it is in the simplu3D directory...

export MAVEN_OPTS="-Djava.library.path=../simplu3D/lib/native_libraries/linux-amd64 -Djts.overlay=ng"
mvn exec:java@export

Export the results to 3DTiles We need to first import the data to 3dcitydb (v4 since v5 does not work with the exporter we want).

docker run -d --name citydb -p 5432:5432 -e "POSTGRES_PASSWORD=changeMe" -e "SRID=25832" 3dcitydb/3dcitydb-pg:15-3.3-4.4-alpine

Then we import our data.

docker run -i -t --rm --name impexp --network host -v ./output:/data 3dcitydb/impexp:latest-alpine import -H localhost -d postgres -u postgres -p changeMe /data/city_union_out_3d.gml

Finally, we export with py3dtilers. We will use a modified version of https://github.com/VCityTeam/py3dtilers-docker because of an update in a dependency.

cd py3dtilers-docker
docker build -t vcity/py3dtilers  .
docker run --rm  -u $(id -u):$(id -g) --network host -v ./output:/data/ -t vcity/py3dtilers citygml-tiler --db_config_path /data/Config.yml -o /data/buildings --crs_in EPSG:25832 --crs_out EPSG:4978 --type building --split_surfaces --add_color

The results can be found in ./output/buildings.

Clean up after yourself: the impexp and py3dtilers containers were already removed automatically (--rm parameter) but the citydb container is still running so remember to remove it when you're done.

docker container rm citydb
