Remove re-linking programs as redundant. It costs (cheaper to link once than twice) and (subjective) is not that common GL API usage pattern, although perfectly legal and permitted. Initial idea, behind the removed code, was to enable work on optimization that would reduce number of attrib setup calls in case when VAO is not available (as described in #9433). As such optimization is not implemented, and it is arguable if it makes sense to do it now, we can remove re-linking. Related to closed PRs #9433 and PR #11583. I have [measured the time spent just on relinking](https://gist.github.com/astojilj/29bd5a5c5dc0b2d9f29ecb660da07fbf) using release build on iPhone SE (A9, same as iPhone 6S): - 1st run after reboot or installation Total 37.14ms, average per program:1.86ms - reopening Total: 2.47ms, average per program: 0.12ms This time we save using the patch here.
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.
