Include a shortcut above bin to the las.exe file

Hi Ajay,
I was thinking it might be good re-configure the left control a bit as follows

• Move the map and settings to the menu button - so the current view that is "always on" on the left hand, can be toggled off/on via the menu button (currently the map is a bit distracting if it is big. no need to have it unless the user needs it)
• Make left/right thumbstick movement to toggle forward and back through time (rather than the clicking on the menu which is not very smooth)
  ** Maybe have the current timepoint listed as text attached to the controller so the user can know which timepoint they are in? Can you add an item in the mod menu to be the text displayed for the name of the current timepoint?
  ** Plan to have pushing the thumbstick up and down toggle data layers for when we get hyperspectral or thermal layers - this will be a layer at the current time point and aligned to the current point cloud, but it would be loaded in place of the current view (e.g. switching between an RGB and hypersectral view)

Thanks

• Drag and drop
  • If one file is loaded, and user ads second one; ask if they want to align/timestamp or drop the first one?
  • Menu to clear current point cloud for loading new one
• Drag and drop
  • If one file is loaded, and user adds second one; ask if they want to align/timestamp or drop the first one?
  • Menu to clear current point cloud for loading new one
  • If user drags and drops a folder holder multiple po-tree folders, ask user if it is a time-series or just BIG
• TimeSeries/Timestamp editor:
  • Over 10 sort order
  • Can we index from 1?
  • After color box is unchecked, reload cloud or provide "reload" button
  • Auto-create TOP.json file at the correct folder level if user is working with a time-series (on save)
• Progress bar doesn't seem to show info anymore (try ACT RGB for example)
• Mod file for first-loaded cloud is not created when aligning - can we give the first file loaded a default mod file?
• Alignment editing menu should be hidden when not in use
• Skybox:
  • Off by default
  • Menu item on desktop and in VR - should save changed value to Top automatically once changed
  • Menu option for choosing skybox
• Issue with point count popup on load
  • On screen
  • On window somewhere?
• Better error reporting on fails
• Keyframe loading doesn't work
• Coloration for non-color files - need to be able to shift the max value so the colors scale even with outliers that mess the scaling up
• ACT-RGB
  • Issues with scaling and movement
  • Weird issues with points flashing

When setting up a time-series, the first-loaded cloud doesn't get a mod file which is a problem when the time-series is loaded.
Perhaps when the user hits "save" if the first cloud doesn't have a mod file you can ask them the time point for that one and then ask again for the 2nd one was already happens?

Once issue 8 is implemented, add teh same thing for numeric data - so the user would load a point cloud and the csv data, then they'd be able to click a point in the data and a point on the point cloud to set where the data belongs. Spatial scaling of data would be a bonus (i.e. user can grab data with both triggers and stretch or shrink it to better match up with the associated point cloud).
When finished,the x,y,z, and scaling values are saved to the json

It's not a big deal when small clouds load, but for big ones or when it is ingesting a huge one (like the ACT or dublin), the window that the folder was dropped from can be frozen for a long time.

Currently if the clouds have different time settings they don't co-visualize so the user can see them to align them

Probably best to do in the non VR version - Have a menu item so the user can load two point clouds, either simultaneously or in time series (whichever is easier to implement), and then pick a point on each one to set the offset values then update the two point clouds to see the results.

See for example: http://data.traitcapture.org/fm/files/pointclouds_potree/618f1ff505ffe2856850142b8f2d4fed2017-03-16-nac-all-abcdefghi-pix4d-r01-merge_group1_densified_point_cloud.laz/data/r/66206/

there seemed to be some issue with the json files from the earlier versions of lasVR so I deleted all json files in the full DIR, but now after it has been processed, when I drag and drop it, it says "can not load tiles in directory".
Maybe this is an issue with the fact that they are laz files? Since you added the ability to read bin files, did you try ingesting any laz potrees? can you try deleting all json in your version of the ACT-rgb and then re-ingesting it?

Thanks

Add menus to expose available features to non VR users

I had some smaller high res point clouds from a lidar plant scanner. No matter what I set the point budget to, the point cloud loads in high res but then switches to a lower tres version and won't stay in high res. I'll upload the point cloud later (don't have it on this computer)

If it it isn't easy to fix, maybe at least disable the "vr mode button if a point cloud has been loaded?

Issue is that loading huge datasets takes forever the first time they load.
Discussed options were
(1) See if this is really necessary or can it be skipped or computed on the fly?
(2) if potree has a completely standard organization format can we impute what files are where and how they are named by some basic metadata, without having to explicitly list them ahead of time? (this is how we solved this issue with our timelapse tools - we have a very standard naming and folder structure so we can calculate the name and location of all data, we never actually check if it is there until we try and load it. This enables our timelapse player be able to play back timelapse of unlimited duration and any timestep and any number of images, assuming the images are named correctly and there isn't too much missing data)

(3) maybe the potree converter can be modified to add the data file listing folder contents when the dataset is initially ingested.

@AjayLimaye can you look into this and get back to me?
thanks

Try the 2017 ones and check the file loads in http://traitcapture.org/pointclouds first

• Angular movement is fixed
• Middle finger trigger rotates left/right
• Trigger finger drags world
• Right thumbstick is movement.
  ** Angle of movement set by stick angle from slow to medium
  ** Top speed is limited
  ** Wrist angle in the vertical axis determines if user is flying upwards or downwards

(1) doesn't seem to work on desktop (assuming it is the left/right arrows that are supposed to switch between times)
(2) In VR it happens really fast - clicking the + or - button seems to register a long keypress until the user stops clicking so the numbers flash and don't change reliably
(3) User's position is not retained when switching between time points.

The dataset I am testing is linked below. timesteps 2 and 4 are well aligned, 1 is not. if you fly to a position in 2 then switch to 4, you jump back to the starting position.

Here is the current time-series dataset:

(1) See issue 16 (#16) - When you hit save from the TimeStamp editor menu:

• Program should check if all loaded point clouds have get mod files - if they don't have them already they should get one
• User should have an option to save the changes for the current selected cloud or all of them.
• Currently settings don't save correct - e.g. if I change the timestamp setting to 1, the mod file gets "time=1" as the value

Thanks
