Same thing happened to me, I think I fixed by swiping left
I'm seriously swiping as hard as I can in every direction.

I'm guessing there's a missing/incorrect OS/functionality check somewhere cause she's on iOS 8.2. Upgrading now and will report back. Also grabbed the crash-logs and will email them through.
I'm seeing the same thing. It looks like the app is calling -[UITraitCollection forceTouchCapability], which isn't available on iOS 8.

#125What annoys me most: "thing disappear" I don't recall 3D -> 2D mapping making things disappear, just surfaces hiding other surfaces. But this might not work in 4D? With the 2D->3D they are taking cross-section, I really don't like these. Just throw it all on there ! This would also mean you project your 4D world on a 3D camera, you project on a 2D surface to display. https://www.youtube.com/watch?v=BVo2igbFSPE <= thi…
I think the difference is projection versus cross-section. A video game is a 3D world projected on a 2D screen. The game is not a cross-section of the 3D world. In this game, you play within a cross-section of the fourth dimension, which you can move along a slider, sort of like a CT scan. That having been said, I don't have any clue what a 4D projection into 3D space would look like. I suspect we would have much mor…
Well look at the video for projection.
But you raise an interesting point, perhaps we could encode the 4the dimension in color or the stereoscopic channel (with VR gear) and remove this channel from the 3D part as we can do 3D without stereo.

A favorite novel of mine actually! Hard to believe that it was written in the 1800s, yet still Abbott understood the 4th dimension better than most people today.
> Hard to believe that it was written in the 1800s Aside from all the misogyny and the style of writing, you mean?
To be fair I think the misogyny was satirical

An easy way to imagine a 4-dimensional structure is to associate every point in 3-space with a color or a temperature. Your mental visualization processes should have no trouble with that. But the system quickly breaks down; the imitation fourth dimension is not in the same class as the other three. You can easily visualize a three-dimensional object rotating around a line in 3-space, or a two-dimensional object rota…
That's why I used time not color: you have an inherent notion of what it means to move things along that axis. Your point about color also doesn't quite hold -- it's easy enough to map the rainbow colors to rotation. It obviously takes practice, but it's not hard. (Helps to start with two spatial and a color.) And of course it's tied to 3 dimensional space -- the whole point is to couple the correspondence between a…
I don't think my inherent sense of what it means for a point to move forward or backward in time is much different from my inherent sense of what it means for a point to get lighter or darker. Neither will help with a spatial rotation.

Yep. For a minute there I was worried this was some Myst-like intelligence test that I was failing.
Looking forward to the be build.

#130It's a shame it's only for iOS and Vive. I wonder how difficult it would be to make an open source desktop/browser version? Even if it's a lot simpler, it would be neat to feel what it'd be like to play around in 4 dimensions.
