Teleport System v2

[FejZa]

XRTK - Mixed Reality Toolkit Pull Request

Overview

This PR fixes #504 and introduces some new features to the teleport system.
The core change is that the act of "teleporting" is now done by "teleportation handlers". Instead of the teleport system just moving the camera around. Using a new teleport system profile the user can configure a handler implementation to use, this opens up endless possibilities to handle teleportation.

Previously:

• Teleport just moves the camera/playspace to target position instantly. That's it

Now:

• You can either just teleport or have e.g. an animation / sound or whatever play when teleporting. It's all up to how the handler implements it

The PR comes with two default implementations.

InstantTeleportHandler

This is what we had so far in terms of looks and behaviour. The user selects a teleport location and instantly is moved there.

FadingTeleportHandler

This implementation will fade in / out the camera before teleporting, which leads to a more appealing and smooth teleport.

Changes

• Fixes: Teleporting does not land on desired landing location #504

Submodule Changes

• SDK
• Examples

Overall love the work, I think it's great we have a proper profile and handlers for this now.

I guess my only concern is that the default implementation cannot be packaged with the core (similar to the gaze data provider which serves a similar function as it is required for the input system to work)

[FejZa]

But don't most of the systems have that issue? Spatial Awareness also won't be able to do anything without SDK.

[FejZa]

We could have a "fallback default implementation" that kicks in if no handlers is available. As soon as one is registered in the system profile it takes over?

[StephenHodgson]

Yeah but the difference with the Spatial Awareness system is that not all platforms could have data providers.

I think it's more like the default gaze provider.

Teleportation is essentially platform agnostic

Got to try out the demos, great stuff Dino!
