[](https://magnum.travis-ci.com/mapbox/llmr-native)
An OpenGL renderer for [Mapbox vector tiles](https://www.mapbox.com/blog/vector-tiles),
implemented in C++11, targeting iOS & OS X.
# Depends
- Modern C++ compiler that supports `-std=c++11`
- `libpng`
- `libuv`
- `libcurl` (depends on OpenSSL)
- `glfw3`
- Boost (for Rtree support)
- Python (for build only)
- Node.js (for build only)
# Build instructions
We use [mapnik-packaging](https://github.com/mapnik/mapnik-packaging) to build static libraries of
dependencies.
## OS X
Run `./setup-libraries.sh`
This downloads all required dependencies, builds them and creates universal libraries that can be
used on both OS X and iOS.
To create projects, you can run:
- `make xproj`: Creates an Xcode project with OS X-specific handlers for HTTP downloads and
settings storage. It uses GLFW for window handling.
- `make lproj`: Creates an Xcode project with platform-independent handlers for downloads
and settings storage. This is what is also being built on Linux.
- `make linux`: Builds the Linux GLFW application with `make`.
## iOS
iOS makes use of a Cocoa-specific API currently housed in [MVKMapKit](https://github.com/mapbox/MVKMapKit),
which is included as a submodule and provides a `UIView` interface to the map view.
First, pull down the submodule(s):
git submodule init
git submodule update
Then, because `libpng` isn't included in the iOS SDK, you will need to build a cross-architecture version
yourself. Run `./setup-libraries.sh`, which is derived from Mapnik's cross-architecture build
scripts. This will also run `./configure`.
Lastly, `make iproj` to create and open an Xcode project with an iOS-specific view controller housing.
Target devices: iPhone 4 and above (4S, 5, 5c, 5s) and iPad 2 and above (3, 4, mini and/or retina).
## Ubuntu
Ensure you have git and other build essentials:
sudo apt-get update
sudo apt-get install git cmake make pkg-config curl automake libtool xutils-dev
Install a `-std=c++11` capable compiler
sudo add-apt-repository --yes ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.8 g++-4.8
Install glfw3 dependencies:
sudo apt-get install libxi-dev libglu1-mesa-dev x11proto-randr-dev x11proto-xext-dev libxrandr-dev x11proto-xf86vidmode-dev libxxf86vm-dev libxcursor-dev
Build static dependencies:
./setup-libraries.sh
This will automatically run configure for you and set the correct paths.
You can then proceed to build the library, tests, or a GLFW app itself.
# Style
We're currently embedding the stylesheet JSON in the binary. To create the C++
file and the associated header, run
```
bin/build-style.js
```
This is automatically taken care of as a build phase.
# Usage
## Desktop
- Press 'X' to reset the transform
- Press 'N' to reset north
- Press 'R' to toggle styles
- Press Tab to toggle debug information
- Press Esc to quit
## Mobile
- Pan to move
- Pinch to zoom
- Use two fingers to rotate
- Double-tap to zoom in one level
- Two-finger single-tap to zoom out one level
- Single-tap to toggle the command palette visibility for resetting north & the transform, toggling debug, toggling styles, and locating the user
- Double-tap, long-pressing the second, then pan up and down to "quick zoom" (iPhone only, meant for one-handed use)
