AR Slow Motion

[Nicholas714]

The AR scene has gravity set very low, causing a slow motion effect. This is intentional. If it was set to normal gravity as in the 3D scene, the blocks would fall. It is known that in AR, the physics engine is not exact to 3D due to the different sizes, so friction does not behave correctly. If it was set exactly like the 3D scene, the blocks would fall and jump around as if there were no friction in the world.

To fix, scale the rootNode to be the size of the 3D node during physics calculations, and then scale it back to normal when it is being rendered. This is a work-around by making the physics engine see the world as if it were in 3D to preform physics calculations, then changing it back so it can be rendered and displayed normally.
