3D Viewer: Also show survey name for station

[Seldor Sore]

Hi

We have a big cave project spanning over around 25 surveys now. Often when having to continue somewhere, we need to know the name of the point and the name of the survey it belongs to. However, in the 3D Viewer, only the station name is displayed. Would it be possible to add the name of the survey(s) the point belongs to? That would make identification much easier.

Thanks Matt

until it is fixed:
3D viewer - Settings - Station dialog:
if enabled it will display the long name in the dialog window

The display of station as dialog already has the full name

The box display has short name

It will be replaced by the full name.

leg comments do not belong to a station

Ah thanks for the tipp with the station dialog, that's great to know!

btw, there seems to be a bug with that dialog: When I select a station, it shows. When I now close this dialog by just clicking somewhere outside the dialog (instead of the cancel button), it closes successfully, but after that, no dialog is ever displayed again. Even when I go back and re-enter the 3d plot, very often it just doesn't work anymore. It seems that closing by clicking outside the dialog leaves some invalid state behind which the close button cleans up. The last selected point also remains selected with a red dot in the plot but no dialog ever opens again until I fully exit from the plot. When I close it via the button, no red dot remains.

Also, if possible, it would be great if the dialog would display all stations from all surveys. When selecting a station that acts as a equate, only one of the stations is displayed and I cannot really find out what other survey (and station name) represents the same point.

Thanks for looking into this

And another thing that happens frequently with the dialog: When zooming in (via two fingers), very very often, one of the stations that was probably hit with one of the fingers during the pinch zoom opens - so when zooming in, I have to close the dialog two or three times until I'm at the place I'm looking for, selecting a station should be disabled during zoom

[Marco Corvi]

station select is already conditioned to one pointer.

the event reported on the first finger touch has one pointer, and it select a station if the touch is over a station.

selection can be switched off.

it is written in the user manual

it was a bug: the red station was not cleared.

thx

equates are consumed in the data reduction.

only the first station remains.

Yes it seems that the station select triggers on finger-down, this means, it also triggers when I just want to rotate/move the model or use pinch-zoom. Or when I just want to drag it around, it will pop up if I accidentally hit a station but then the model still moves in the background while I keep the finger down and move it around on the screen, that's a bit strange. Don't you think it would be much better to instead trigger on finger-up (as long as it didn't move/zoom during the action)?

I love the dialog now that I know about it, but then again it keeps popping up when I just want to move around in the model, I'd expect it to only show on a 'click' (meaning a short tap).

Thanks a lot

that is the reason why the selection can be switched off

That sounds more like a workaround than like a fix? With enabled station selection, scrolling around the plan is very tedious - disabling it every time I want to scroll around isn't really a fix but a very ugly workaround.

Would it be hard to fix the logic to consider only a tap for the selection of the station? That would fix all usecases and make the station dialog usable again

Thanks for your consideration

Matt

[Marco Corvi]

not that straightfirward because a tap is made of several events and each event is handled :

selecting a station on one-pointer up instead of one-pointer down would not solve the problem, because the model rotates behind the screen.

how would you set the logic ?

long tap - not move

or

tap - not move - release -> selection

tap - move - release -> rotate

?

Although the most used function of topodroid is sketching, I think that the 3D viewer if the feature that really singles out topodroid from other apps.

Thus it is worth making it better, both in functionalities and UI/UX.

i think it can be done with some variable that keep tracks of past events.

this get rid of the selection state variable,

and four icons in the drawable.

at the same time the tap time can be used to decide between the bottom station-bar and the station-dialog.

both have pros and cons.

right now the dialog does not have a lot, although it has room for more infos.

the bar has actions, that cannot fit in the dialog because it covers the display

this get rid of a setting and a couple of strings.

but the man-page gets a bit longer.

Hi Marco

Yes that sounds like a great idea, using short and long press to select between the two is also much better than a preference which must be changed regularly based on the current need.

What 4 icons would go away? I don't understand that part.

And one small addition that could make your life easier: as soon as you detect more than one figer (e.g. for pinch zoom), you also know you're never in station select mode anymore until all fingers have lifted again.

Thanks for your work

Matt

already taken into account in v. 6.4.92, and maybe before that.

Great, will be watching your release page to try it out then! The 6.4.92-36 link points to a 404 and I'm reluctant to download the .94 preview as it's ' strictly to test BACK button and CLOSE menu ' unless you say it's safe...

Thanks Matt

you can decide to be among the users willing to test a version that might hang ... or crash - or, better said, has more chances to hang / crash.

these users are very important to find bugs and help fixing.
