    can you send some sample files where it fails?

    then that probably fails due to trying to initialize so big array, i can test it locally with a dummy file to see what happens.
    with the coming v3 format it should work. (almost ready to submit it, should be live by next weekend).

    I had a memory error when trying a larger file too. It was definitely at the vector3 array initialisation, but happy to hold off until we get v3. Was thinking about just forcing it to split into multiple smaller output binaries if bigger than some threshold size, but wasn't sure about the randomisation factor.

    edit: fixed in 2.20 thanks!

    Hello to all... Is it possible to load multiple .ply files for animation with this tool ? I saw in releas-note there is possible to load brekel format for animation.

    Not possible in the current version,
    but i had external converter tool for doing exactly that, i'll check if can find it.

    Hello again mgear, I am trying that tool with .ply Asci 1.0 format with few files. I have some issue:
    upload_2019-11-20_22-18-5.png
    CloudCompare can read one file right. For what kind of format .ply is it ?

    If I good understand, with Point Cloud Tools it is possible to play animated .bin and also multiple ones,please ?

    is it ascii ply? can you show the header of ply? (or email me sample file)

    animated .bin file is single file only (not multiple .bin files),
    so the ply converter puts all ply frames into that one .bin file.

    animated .bin file structure info is here (in case you want to output data yourself from elsewhere)

    yes, basic ascii pcd is supported.

    if you want to send sample file to try first, i can test and pm/email you screenshot.

    Planning for the next updates, here are some options (that you can vote on, or suggest new ones)

    can vote with this link:
    https://www.strawpoll.me/19045290

    or comment here in forums:
    1. Add pack-colors feature for v3 (~1.5x performance boost)
    2. more import formats to commandline converter tools
    3. add point picking to v3
    4. faster loading v3 (and load near player first)
    5. v3 load tiles from web server
    6. v3 animated lod fade in out (instead of instantly appearing)
    7. v3 load/unload on demand "=unlimited point cloud" (currently fully loaded into memory)
    8. Something else (post in forum)

    *of course i eventually want to put all those and more, but you can comment on what is most important right now.

    Would this require a performance hit with 2 LODs active during transitions? Cool idea, but probably 2nd level of importance to me.

    I'd really like to see 1, then 7 as most useful to me.

    Thanks, I look forward to seeing what you get to next :)

    have a great day

    Hi,

    I just bought the plugin of yours.

    I am generating points from Unity C# Script editor.

    For instance

    Vector3[] positions = new Vector3[100000];
    for(int i = 0; i< 100000; i++){
    positions = new Vector3(0,0,i)
    }

    How can I display positions in Unity once I press start?

    check example scene:
    PointCloudTools\Demos\PointCloudViewer\Scenes\PointCloud-YourOwnData.unity
    and the script used there:
    PointCloudTools\Demos\PointCloudViewer\Scripts\YourOwnDataExample.cs

    so in that example, when you press Space, it generates random points and assigns to the viewer,
    you can do the same. (note that in the start is sets RGB true, so if you dont need point colors, can set that to false.

    there should be no performance hit, but i realised that probably user wont notice it much in most cases (if they are further away from viewer anyways)

    yeah, #1 and #7 seem most useful at the moment.

    Is it necessary to add colors or this property could be skipped?

    tested, it works without colors also, so no need to feed colors.
    (for the viewer you can assign material like "PointCloudSingleColorOpaqueDX11.mat", so you can then set point colors.

    no runtime version yet, actually my initial thought for v3 runtime conversion was to call commandline converter in background to do it.. (after adding new commandline formats, currently only laz/las has commandline v3 converter).

    currently you can get these values out from the v3 cloud, Bounds and the Offset that was used for autooffset:
    https://github.com/unitycoder/UnityPointCloudViewer/wiki/V3-Tiles-Format#api

    i think there is no way to keep objects in real coordinates (since everything breaks too far)..
    so certainly would need to offset the other objects to match the autooffset.

    that can help also, it actually tries to load the dll from same folder, but i wanted to have the main folder clean.. so it then falls back to lib folder in case of failed dll.

    So it is hands down one of the best updates so far but is limited(because who else needs the resources that we do?!). Is there a way to adjust and or address the OutOfMemoryException(is this C++,C# limits or...??) Potentially with something like page files to collect dumps and/or in the building process dump files an/or split into chunks?

    The Laz file was 2.7gb, the LAS was 28gb. It seems that the limitation is actually based on the quantity of points and therefore maybe a buffer is being generated so isntead, break the buffer into 2 chunks? I have 64gb memory and 58gb was available at the time, so not sure.

    ex. getPointCount(); --> if pointCount >= 500,000,000 --> convertPointToPCROOT() --> readFile() --> makeList() --> if points fall in tiling range (based on bounds and tiling info)--> export into new file chunks --> organize(); --> Final Process using small chunks to make the large chunk().

    or like getPointCount(); --> if pointCount >= 500,000,000 --> chunking files() (( create list with first half of points, dump to file, get second half of points and amend to file). organizeFile(); --> tilingChunksBasedOnMetersAndPointSpacingFromFile() --> etc etc

    in theory if memory exception is correlated to memory available on the system, you could future proof this for any rig to run it, example is whatever the max memory is, you can run an algorithm to ensure the process stays within an acceptable range and adjust processing based on such settings (more chunks to reduce chance of overwhelming system) Bigger machines would stand to benefit the most, possibly too if it was tied into threading, but even resource deprived PCs could have their fun with PCs too.

    yeah, for huge files need to add something to overcome that limitation.
    current workaround would be to manually split the cloud into 2 parts, and then use 2 viewers. (havent actually tested that)

    Not yet, but i'm adding that as an standalone commandline converter (which can be called in the background to do runtime conversion). (but probably not in the next few weeks though)

    V2 or V3 format is not supported for LAS. Check standalone converter: https://github.com/unitycoder/UnityPointCloudViewer/wiki/Commandline-Tools#laslaz-converter

    please make the comand line have a simple UI, comandline is allways a pain

    So downloaded latest version, willing to test v3 format

    I've a really large dataset for testing, the thing is that is is already tiled and in .las

    aparently the converter spects you to input a mega massive dataset and itself will generate the chunks/grid for v3 format, at least on unity editor seems like so.

    I also have the dataset merged, but handling big datasets in a single file is allways a pain. Would it be possible ( may be its already) to batch convert a folder with .las files to v3 format and use each file as an independent region in the lod? And in the viewer just point the root of the folder you whant to completely load.

    So i managed to convert my .pod microstation cloud to a 30gb xyz cloud. I'm trying to convert it to v3 format using the editor converter.
    1/3 Counting rows= 0

    looks like its bonna take long.

    the dataset:
    upload_2019-12-18_15-9-17.png

    I think its 730M points, all merged in one file.
    75m grid size

    note:
    editor converter is about 5-10x slower than commandline version..
    also, you can skip that counting part if you use PTS format (where it has the pointcount amount on the first row)

    but excellent feedback, got few ideas to handle large clouds better.

    makes me doubt wether I may have placed another merge cloud since the AO is baked on the rgb there should be RGB data.
    So I checked with CC and its true, only XYZ, I may have removed RGB data hwen exporting from MS.
    I checked and MS only exports XYZ no XYZ RGB, at least on the version I've.
    CC I tested in the past and could not handle the merge process of the several tiles. I may retry tho.

    so, I managed to export to .las the whole cloud with the AO so it would not render as a white massive cloud. Yet

    "Excepción no controlada: OutOfMemoryException." is what I get with the commandlin converter, almost instantly

    with the .xyz in editor it won´t trow err but it simply wont output a file.

    I think it would be great as I stated above to be able to import a whole folder of already tiled clouds and each file be treated as a tile or even be able to further subdivide each tile if necessary.

    For me, the tests go as far as this as this for now. If you whant the big .las file I can send you, I can send you also the chopped version

    Hello to all again... is it possible to load .bin file in editor without "play" ? Is it possible to make translation to cloud in editor (move,translate, scale) ? ...btw, great plug-in.

    this is the only editor viewing option currently, but has issues (also need to disable threading, might have had some other issues too)
    https://github.com/unitycoder/Unity...wing-Point-Clouds-in-Editor-(not-in-playmode)

    i'm guessing you'd like to build levels using pointclouds, arrange them around and use as reference etc. ?

    then initial thought would be making lower resolution mesh clouds to work with,
    and some custom tools to collect/save those translation values into binary viewer..

    to translate binaryviewer clouds, would need to modify shader to add offset/scale/rotate (to do that inside shader).

    Thank you, I was hoping also for animated pointcloud in editor :)

    I would like to build presentation from multiple pointclods and also some of them are animated. Kind of VR documentation from photogrammetry and multiple kinects sources.

    Hi

    I just tried to display pointcloud from my project, but I get null error.
    Why this error happens and why points are not displayed?

    Have you assigned viewer reference in inspector? (like in the yourowndata example scene)
    on this field: public PointCloudViewerDX11 binaryViewerDX11;

    btw. is that faro dll publicly available? looks like it would be easy to add support for that format then.
