Using finger's Y axis position allows for a linear zoom additions/deductions during the quick-zoom changes. This is in contrast to the previously used scale factor, which is based on the current span (distance from the origin) to previous span ratio and increases the closer the finger is to the origin of a gesture because the values are smaller. The scale ratio based changes are also reliant on series of motion events' values and because the Android framework can skip some events, going back and forth during a quick-zoom might not have resulted in the same transformation. This was reproduced by the round-tripping test introduced in this commit.
Mapbox GL Native
A library for embedding interactive, customizable vector maps into native applications on multiple platforms. It takes stylesheets that conform to the Mapbox Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using OpenGL. Mapbox GL JS is the WebGL-based counterpart, designed for use on the Web.
The Mapbox GL ecosystem
This repository hosts the cross-platform Mapbox GL Native library, plus convenient SDKs for several platforms. The cross-platform library comes with a GLFW-based demo application for Ubuntu Linux and macOS. The SDKs target the usual languages on their respective platforms:
| SDK | Languages | Build status |
|---|---|---|
| Mapbox GL Native | C++14 |   |
| Mapbox Maps SDK for Android | Java | |
| Mapbox Maps SDK for iOS | Objective-C or Swift | |
| Mapbox Maps SDK for macOS | Objective-C, Swift, or AppleScript | |
| node-mapbox-gl-native | Node.js | |
| Mapbox Maps SDK for Qt | C++03 | |
Additional Mapbox GL Native–based libraries for hybrid applications are developed outside of this repository. If your platform or hybrid application framework isn’t listed there, consider embedding Mapbox GL JS using the standard Web capabilities on your platform.
