vectiler
A wavefront obj vector tile builder and exporter based on mapzen vector tiles.
- build and export mesh in obj files based on tile coordinates (find your tiles of interest here)
- bake ambiant occlusion and save it in an atlas (using aobaker)
fetch submodules
First initialize submodules by running:
$ git submodule update --init --recursiveinstall dependecies (OS X)
aobaker needs embree for optimal ray tracing and tbb, you can install it using homebrew:
$ cp 3rdparty/aobaker/embree.rb /usr/local/Library/Formula
$ brew install embree tbb cmakebuild
To build with cmake in a build/ directory run the following:
$ cmake . -Bbuild
$ cmake --build buildusage
Usage: ./vectiler [options]
Options:
--name File name ((null))
--apikey Developer API key (https://mapzen.com/developers/) (vector-tiles-qVaBcRA)
--splitMeshes Generate one mesh per feature in wavefront file (0)
--tilex Tile X (can be a tile range: 19294/19295) (19294)
--tiley Tile Y (can be a tile range: 24642/24643) (24642)
--tilez Tile Z (zoom) (16)
--offsetx Global tile Offset on X coordinate (0.0)
--offsety Global tile Offset on Y coordinate (0.0)
--append Append the obj to an existing obj file (0)
--buildings Whether to export building geometry (1)
--buildingsExtrusionScale Building height scale factor (1.0)
--terrain Generate terrain elevation topography (0)
--terrainSubdivision Terrain mesh subdivision (64)
--terrainExtrusionScale Terrain mesh extrusion scale (1.0)
--aoBaking Generate ambiant occlusion baked atlas (0)
--aoAtlasSize Controls resolution of atlas (512)
--aoSamples Number of samples for ambient occlusion (256)
--version Output version
--help Output help
terrain
Terrain export is an experimental feature (data is only available in California).
./vectiler --tilex 5242/5260 --tiley 12642/12666 --tilez 15 --terrain 1 --buildings 1 --terrainExtrusionScale 1.5 --buildingsExtrusionScale 1.9

Download one tile with ambiant occlusion baked in a texture:
./vectiler --tilex 19294 --tiley 24642 --tilez 16 --sizehint 512 --nsamples 128
Output files are:
[tilex].[tiley].[tilez].obj: a simple mesh containing coordinates and normals[tilex].[tiley].[tilez]-ao.obj: a mesh containing coordinates and texture uvs for ambiant occlusion rendering[tilex].[tiley].[tilez].png: an atlas containing the baked ambiant occlusion
Download a big tile, in a file named manhattan.obj from a shell script:
./vectiler --name manhattan --tilex 19293/19298 --tiley 24639/24643build and run the viewer (OS X)
A minimal viewer using oglw can be used to preview the obj tiles:
$ cd renderer
$ cmake . -Bbuild
$ cmake --build build
$ open viewer.app --args ~/dev/obj-export/build/19294.24642.16-ao.obj ~/dev/obj-export/build/19294.24642.16.png
