vectiler

Platform	Build Status
OS X/Linux
Windows

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)

export example

• sketchfab.com/e7ee1c
• sketchfab.com/693df3

fetch submodules

First initialize submodules by running:

$ git submodule update --init --recursive

install dependencies (OS X)

$ brew install cmake

install dependencies (Linux)

To build vectiler you will need a compiler that supports c++11, for example with g++-4.9 on an ubuntu machine:

$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt-get update
$ sudo apt-get install g++-4.9 cmake libcurl4-openssl-dev

build (OS X/Linux)

To build with cmake in a build/ directory run the following:

cmake . -Bbuild
cmake --build build

build (Windows)

First install CMake for Windows and then run the following commands in a command line tool like MinGW:

$ mkdir build
$ cd build
$ cmake .. -G "Visual Studio 14 2015 Win64"
$ cmake --build .
