mojo3D – util.Fly() for mobile?

[DiffrenzyKeymaster]

Anyone got one?

I think you can touch left for rot left, right for rot right, center for move foward.

ok, but I’m lloking for a complete dropin that does pan, tilt(rotation), zoom and rotation.

Based on the way they do it in Google maps ( https://www.youtube.com/watch?v=aKulxv-26mo ) it could be:

1 finger = pan

2 fingers:

pinch = zoom

angles between fingers delta =  Z rotate by this amount

2 finger pan : XY rotate model

Can monkey support gestures? I have not tried mobile yet.

Util fly was a 5 minute hack designed to do 3 things: rotate left/right and move forward! So no, it doesn’t do gesture recognition etc.

I got 2d scale/drag/rotate going quite nicely I think – see touchtest banana – but I haven’t attempted 3d as yet. In fact, I don’t think I’ve even seen any examples – can you describe a bit more clearly what you’re after?

[DiffrenzyKeymaster]

I tried out touchtest banana, and it comes very close to what i’m looking for.

if 1 finger could then rotate the model, we’d have a cool quick way of looking at 3D scenes.

To make it more versatile, it would be nice if the same Fly() would work on desktop.

PS: Mojo3D is really nice

pinch/zoom doesn’t quite work in 3d though does it? You want pinch/move which is a bit different, or do you keep pinching over and over to move?

And how would rotate work? Swipe left/right? Or hold and drag to look? Would be good to learn how swipe works anyway…

It was be nice to see an example! Any recommendations for android/ios?

[DiffrenzyKeymaster]

Yes, I guees Fly() is the wrong name for this, just pinch a bunch of times to zoom, this is not for a FP shooter, only for viewing a model.

I like  the Sharpr3D method, because it leaves the 1 finger free to do other stuff, however two fingers is not ideal on a small phone screen.

Get it from https://itunes.apple.com/hu/app/shapr3d/id1091675654?mt=8&_branch_match_id=442203562782760740

Modeling is only for iPad Pro, but there is a “view only” mode for normal ipads that does what I describe below.

This is what I’m looking for: https://www.youtube.com/watch?v=UsupbPZPOfU

Here is a guy dooing the rotation in unity: https://www.youtube.com/watch?v=S3pjBQObC90

I don’t think the actual swipe gesture is needed for this, just 1 finger move.

How about this:

Pinch = move the camera in /out (zoom), whilst LookAt() the model (or 0,0,0)

(Sharpr3D also pans the LookAt() center, when you move two fingers)

1 finger move/left mouse button + move = Camera moves in a circle (sphere), while looking at the model (or 0,0,0)

Shortest screen dimension swipe/move finger equals 180 degrees rotation on that axis.

Example in portrait mode: Touch center of screen, move finger to right edge of phone = rotate camera CCW 90 degrees around Y (assuming Y is up)

Not that important but:

Two fingers rotate = Rotate the camera around the camera.Pos – LookAt() axis, hopefully camera z axis ?

This brings me an idea of capturing this turning this touchtest into a nice component.

This is a rough sketch I made of the design to get an idea of where is going, when I will actually start doing mobile I will return to this thread and post an update. For more information I will also examine other engines just to clear things out and avoid any confusion on the API.
