Hackathon Proposal: more diversified facade textures osm2city

Title:	Make diversified facade textures for osm2city buildings Warsaw area with OSMcity buildings
Sponsors:	vanosten
Interested Parties:	none
Status:	n/a
Summary:	Drastically improve the look of buildings in osm2city
Background:	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
Details:	n/a
Required skills:	Python or 2d graphics drawing with layers (you do not have to be an artist)
Learning Opportunities:	* 2d graphics drawing Python C++ and TerraSync
Notes:	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 E.g. based on PixelCity as referenced in AutoGen_Scenery_for_FlightGear.
