What is the difference between Mapbox GL JS and Cesium? - mapbox-gl-js

Google earth API has been abolished.
It seems that the kml file used in Google earth can be used in Cesium. Can it be used in MapBox GL JS?
Cesium does not have complete 3D building information.
MapBox GL JS has prepared 3D building information, but I don't know if it can be freely developed for in-house Web applications.

Cesium and Mapbox-GL-JS are both Javascript libraries for displaying maps using WebGL. Other than that they're extremely different. Cesium supports a globe view, 3D tiles, full 3D, textured meshes and tons of other things. Mapbox-GL-JS supports 2.5D (that is, a 2D shape with height), with limited support for compositing true 3D objects using other libraries such as Three.JS.
Cesium does not have complete 3D building information. MapBox GL JS has prepared 3D building information
Cesium and Mapbox-GL-JS are just rendering engines. However, Mapbox.com provides basemaps that contain building data.

Whether offline maps are charged by Mau, tile requests, or both

In Map_SDK_V6, you can see that it is charged according to the tile requests, but there is no charging content in v10. Is it cancelled?
Your offline tile usage will be billed as Vector Tiles API or Raster Tiles API requests.
According to the following paragraph, the Mapbox SDK includes Mapbox SDK contains vector Tiles API.
Which Mapbox services are included?
Maps SDK MAUs cover any use of the Vector Tiles API and Raster Tiles API in an application that includes the Maps SDK with no upfront commitments or annual contracts. These APIs are used, for example, when displaying a map view and panning around the map.

ARCore in unity vs Sceneform features/use cases?

The way I understand it is that there are several environments that support ARCore and Unity and Sceneform SDK are some of the options.
I was wondering how are they different from each other besides one being in Java and the other being in C#? Why would someone choose one over the other aside from language preference?
Thank you
Sceneform empowers Android developers to work with ARCore without learning 3D graphics and OpenGL. It includes a high-level scene graph API, realistic physically based renderer, an Android Studio plugin for importing, viewing, and building 3D assets, and easy integration into ARCore that makes it straightforward to build AR apps. Visit this video link of Google I/O '18.
Whereas ARCore in Unity uses three key capabilities to integrate virtual content with the real world as seen through your phone's camera:
Motion tracking
Environmental understanding allows the phone to detect the size
and location of all type of surfaces: horizontal, vertical and
angled surfaces like the ground, a coffee table or walls.
Light estimation allows the phone to estimate the environment's
current lighting conditions.
ARCore is Google’s platform for building augmented reality experiences. Using different APIs, ARCore enables your phone to sense its environment, understand the world and interact with information. Some of the APIs are available across Android and iOS to enable shared AR experiences.

What does GL in 'Mapbox GL JS' stand for?

I couldn't find it in the introductory docs
https://www.mapbox.com/help/how-web-apps-work/#mapbox-gl-js
Thanks
GL is a reference to WebGL (Web Graphics Library). So it stands for 'Graphics Library'
https://en.wikipedia.org/wiki/WebGL
Mapbox uses Mapbox GL JS, a client side renderer, so it users JavaScript and WebGL to draw the data dynamically with speed and smoothness of a video game.
A more detailed explanation can be found on this SO answer...
Mapbox GL JS vs. Mapbox.js
Esentially MapBox GL is a upgrade of Mapbox JS to exploit the client side WebGL technology (amongst other upgrades).

Extracting and using street data from MapBox iOS SDK

Is there a way to identify streets and roads on MapBox maps and get information about their shapes, etc?
I am talking about something like this: http://www.playmapscube.com/ The ball follows the paths created by streets.
Nope: the Mapbox iOS SDK's maps are tile-based rasters, so they don't contain street data as much as a representation of data as an image. In Mapbox GL Cocoa, it's possible to get at raw data, but it'll require a bit of experimentation, since it's a very new project.

Any possible way to develop 3d earth map application for iphone?

I need to develop an iPhone 3d map application similar to virtual earth or google earth. The application will have images overlay above the 3d map, like clouds or location pin. Anyone has any ideas on that?
Regards
Edit:
Try to make the phrase not vague this time:
As far as I know, google earth and microsoft virtual earth api (3d) are not supported for any iOS devices.
In stead of redoing everything from ground up using OpenGL ES, which is the only way to do 3d in iOS devices with hardware acceleration, I want to develop a map application with established map services, such as google map. However, the map will be in 3d.
Of course, I can make a simple 3d earth using openGL ES with hardcore geo location similar to living earth HD, but I try to avoid that.
Have a look at WhirlyGlobe library : http://code.google.com/p/whirlyglobe/
You can also check out eeGeo's iOS and Android SDK, which offers vector-based 3D maps for all of the USA, Canada and UK.
