||Make diversified facade textures for osm2city buildings |
Warsaw area with OSMcity buildings
||Drastically improve the look of buildings in osm2city
||The current texture atlas for osm2city has its limits:
- only one atlas
- very small
- based on pictures from real buildings
- no regionalisation
- facades and roofs intermixed
We need to be able to have a larger diversity of facade textures - per building types and for more building types (e.g. industrial buildings, warehouses, summer houses).
The idea is to :
- keep the current Python-based format of registration per texture, as it has enough properties (to be verified)
- create several atlases - each atlas being defined by a defined geometric rectangular puzzle of pods and nodes
- ability to use different atlases per building (e.g. facade vs. roof)
- ability to use regional textures (e.g. family houses look quite different in different regions, while office buildings look the same).
During the hackathon a PoC would be done for:
- Deciding on the image format for original editing: file naming, layers, editing program (e.g. Gimp or Krita)
- Deciding on the atlas pods and nodes
- Creating a set of textures for commercial /office / sky-scraper facades (relatively geometric) and a set of textures for family houses
- Make the code to display these buildings in osm2city
- Make the code to have the osm2city atlasses available in TerraSync models - and get read from there
||Python or 2d graphics drawing with layers (you do not have to be an artist)
||* 2d graphics drawing
||An alternative for someone wanting to write relatively simple Python code and work with graphics would be to work with the Python API of e.g. Krita to generate lightmaps in a smart way:
- a lot of buildings textures have currently too many windows lit
- maintaining light maps should be automated to lower maintenance
