It is believed that many inexperienced people are at a loss about the new features newly released by JavaScript API GL. Therefore, this article summarizes the causes and solutions of the problems. Through this article, I hope you can solve this problem.

Baidu Map JavaScript API is a map engine product aimed at browser map application scenarios. Since its launch, it has accumulated a large number of users, and the number of service calls has reached hundreds of millions of times a day. With the continuous upgrading of developers' business, the traditional 2D tile drawings can no longer meet the needs of developers. In the call of developers, we have completed the upgrade of the ability of the basic map engine, and the JavaScript API GL version based on WebGL has been officially launched.

Compared with traditional 2D tile maps, the most direct improvement of the new JavaScript API GL is that the map has changed from 2D to 3D, and developers are free to control the rotation angle and tilt angle. At the same time, the map supports infinite scaling, and the maximum scale changes from 20m to 5m, which can support more fine map scenes.

At the same time, the Earth Mode Map, which is unique to Baidu Maps, is also open to developers in the GL version.

Common map capabilities, such as basic coverings, map interactive controls, etc., are also perfectly translated to the GL version to ensure that developers have a consistent or even better experience.

In addition to the above basic mapping capabilities, the most amazing thing about GL JavaScript API is a series of cool map dynamic effects, which can be well applied in all kinds of business operation activities and large screen display.

The first is trajectory animation-how to highlight a trajectory and better show the dynamic effect of the trajectory?

Combined with visual angle animation, JavaScript API GL can help developers display tracks on maps in the form of dynamic effects to achieve vivid and more powerful data presentation.

Secondly, JavaScript API GL also directly opens map custom view animation, and developers can control the dynamic effects of map view changes according to their own business needs. In 3D scenes, they can get an "immersive" map experience. This feature can also be directly applied to the LBS game developer business.

In order to continuously improve the product capability, the upgrade version of personalized map based on GL version has also been arranged. Map engine upgrade WebGL, with a broad map application capabilities and display effect to improve the space, in the next version, we will try to explore more professional, advanced, cool map features, please developers look forward to!
