We have an "oldBinding" value that we use for checking whether the vertex attribute was already bound to the current VAO, but we never set the state. Additionally, we're also checking whether the previous state was already any binding (optional is set), and don't re-enable the vertex attribute array. Additionally, we now only disable the vertex attribute array when the previous state was in fact an array attribute. We still don't deduplicate constant glVertexAttrib* calls, but that's a little trickier.
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 Android SDK | Java | |
| Mapbox iOS SDK | Objective-C or Swift | |
| Mapbox macOS SDK | Objective-C, Swift, or AppleScript | |
| node-mapbox-gl-native | Node.js | |
| Mapbox Qt SDK | C++03 |
Additional Mapbox GL Native–based libraries for hybrid applications are developed outside of this repository:
| Toolkit | Android | iOS | Developer |
|---|---|---|---|
| React Native (npm) | ✅ | ✅ | |
| Apache Cordova (npm) | ✅ | ✅ | Telerik |
| NativeScript (npm) | ✅ | ✅ | Telerik |
| Xamarin | ✅ | ✅ | Xamarin |
If your platform or hybrid application framework isn’t listed here, consider embedding Mapbox GL JS using the standard Web capabilities on your platform.
