Example for SceneKit content in the course view

[1ec5]

Inspired by the example in mapbox/mapbox-navigation-ios#1012, we could add an example of using SceneKit content as the course view. Instead of a flat car image, it’d be a really rudimentary 3D car model along these lines that rotates and tilts along with the map.

On a lark, I took a few minutes to explore this idea but didn’t quite get to the point of a working example. I left my findings in mapbox/ios-sdk-examples#111 (comment).

This page lists some good sources of freely licensed STL files that Model I/O can import as assets.

#117 adds an example of using a glTF model as a user location indicator, which partially addresses the same use case as SceneKit. SceneKit serves a slightly more advanced use case of dynamic content that’s better integrated with application code. mapbox/mapbox-maps-ios#154 demonstrates using SceneKit in a custom layer (formerly called an OpenGL style layer), which is separate from the location layer that navigation SDK v2.0 will come with built-in support for.
