ARKit in Axway Titanium SDK

Use the iOS 11+ ARKit framework in the Axway Titanium SDK.

Thoughts

Supporting ARKit does not simply mean to write some public methods that people can use to "support ARKit in their app". It means to write API's for SceneKit, SpriteKit, ARKit and all bindings around those frameworks. The current implementation starts by creating new scene-views where objects can be placed in.

That's why it is not clear, yet, what kind of API's should be supported and which one don't. I would recommend everyone to open a new issue and leave his/her thoughts regarding their ARKit use-case with Titanium, so the explicit implementation can be scoped.

Until then, it does not make sense to port ARKit example to Titanium, since they will always be limited to the exact example-usage, without the possibility of customizations.

Requirements

• [x] Titanium SDK 6.2.0 and later
• [x] Xcode 9 and later
• [x] iOS 11 and later
• [x] Basic knowledge of computer-graphics and vector-/matrix-operations 😚
• [x] Creativity!
