I love how he explains in high detail what XYZ position means and then breezes over normals like they're nothing

[@Holocreators]

yes, should have gone into more detail there.

[@tokyospliff]

@@Holocreators It's a great video. It's always hard when explaining graphics and other complex concepts to find the right balance between interesting, useful, and digestable. You did a good job.

[@ramananrj2534]

This is the first video im learning about point cloud. Short and crispy explanations. Awesome. I got little bit about point clouds. Thanks my guru

[@Holocreators]

Glad you enjoyed it!

[@RVS_3D]

Excellent video.. I worked for 12years using 3d systems, and until today, many colleagues don't know the difference between scan data..

[@Holocreators]

Thank you!

[@jayfunches]

Awesome 4.52 min Boot Camp Video! Very Helpful!!!

Thanks Jay, happy if you found it helpful.

[@kosmatification]

Hello, i would like to ask a question, in which circumtances, better to use total station? A mean we say lidar scanners are the best, more useful, time benefit. But is there any situation which the laser lidar scanners are less useful than the total stations? (pls except cost of the device or time, i am curious why we use total stations then?)

[@Holocreators]

What is total station?

[@kosmatification]

@@Holocreators Total Station, Electronic Distance Meter, measuring the angles and using in the field to work with coordinates

[@palaunusantara]

Thank you, this is very simple explanation about point cloud , great video and very informative

Glad it was helpful!

Great clear and direct explanation. Many thanks.

Thank you James

[@deborageradts369]

Does every 3D-scanner use point clouds? How do you know if it does or doesn't? And if I have a STL-file of my scanned object, can I transfer it to a file with point clouds?

[@Holocreators]

Hi, every every professional 3d scanner should be able to export the 3d scan in a point cloud format. I have never tried the reverse way from stl to point cloud, but it should be possible. A stl file is basically nothing else then a lot of vertex points connected by lines which then form polygons

[@deborageradts369]

@@Holocreators I used the WIllowWood Omega Scanner, do you know if that one has point clouds? And do you need to save it as a specific file or does a normal stl-file also capture the point clouds? Thank you!

[@Marius-vw9hp]

I am a visualization student and I want to learn more about processing these filetypes. Do you know any place I can find example pointcloud data files?

[@Holocreators]

Just google for *.ply *.las *.e57 There should be something that you can download.

[@joseignaciocamacho2041]

Great video! Is there any software in wich I can link 2D images to a specific point in the point cloud and visualize them? For example, link the three axis of a tomography image (axial, coronal and saggital) that are relative to each specific point in a point cloud, so I can have a 3D representation but also a multi image 2D representation. Tanks for your help!

[@Holocreators]

Hi José.Thank you. I can't think of an out of the box software that can do that, (that doesnt mean it does not exists :-) But it can surely be visualized within a 3d software like blender. It wouldn't be interactive though. More like a video presentation.

[@mohsinpathan7692]

@ holocreators thank you so much for explain whati is point cloud

[@Holocreators]

Happy to help!

[@mdwecht]

Great work! You seem to have done a lot of research on point clouds. Can you point me in the right direction to identify existing point cloud processing libs that might allow me to programmatically determine the dimensions of objects such as a picture frame hanging on a wall?

[@Holocreators]

unfortunately I don't know how to do that

[@mohsinpathan7692]

@ holocreators i’m doong point cloud project of services electrical conduits issue coming on QC we are doing like in navis all rcp of conduits linked and after completing model export revit to navis and append into navis for Qc but its getting heavy so any software for QC revit to point model

Hi, whats the question exactly?

[@jellyfish8781]

This is really clear and helpful ! Thank you !

[@Holocreators]

thank you

[@engriyadadel2784]

CAN YOU PROVIDE FOR US HOW TO PROCESS POINTS CLOUD USING CLOUD COMPARE

[@Holocreators]

hey, there are many wonderful tutorials from other people on youtube how to use cloud compare

[@shivamchandel3922]

Which programming languages do these software's use?

[@Holocreators]

I think python is used for gom inspect

[@artemiofava5754]

Hi Swan, Great video. I would like to see a scaner in action and some theory about how it Works. May be you could do a video about that. Best regards

[@Holocreators]

Hi Artemio, thanks I have done some videos about the theory behind some scanners. Did you check out this one? kzbin.info/www/bejne/fGLIiKSilNiJfqc Have great day.

[@elvissanchez2703]

There should be courses on these topics! Thx!

[@Holocreators]

There are probably. That's just my take on it.

[@JV-gi1hs]

Thanks for the insight, Which software are free?

[@Holocreators]

Cloud compare is free.

[@ganeshshankar7604]

Thanks for the explanation It was very helpful. I am working on building an android application to render using Point Cloud Library. And I am now stuck and confused about where to start with. Can you suggest the technology and resources that would help me in this process?

[@Holocreators]

Hi Ganesh, unfortunately i can't help you there. I am not familiar with android applications. Kind regards. Swann

[@silentzero5916]

I’m actually working a project on generative design which does involve 3D scanning in my case. I’m using a Sense scanner by 3D systems, it’s my first time using this particular scanner and I find it rather difficult to work with. If anyone has worked with it, tips would be appreciated. I’m also interested in photogrammetry, I recently discovered it and Meshlab. I will probably test this out and compare it to my sense scan.

[@Holocreators]

Do you mean the sense scanner that attaches to an Ipad? I did some figure scanning with that 2 years ago.

[@silentzero5916]

Holocreators GmbH Well I’m actually using my laptop but I do believe they have a version for an IPad as well.

[@Holocreators]

@@silentzero5916 thanks, I've got to chech that out.

[@hibbanzmksyr2033]

can the poincloud measure the length of some object??

[@Holocreators]

yes, you are able to extract distance values from the point cloud

[@pbnn735]

Great video, perfect that you show what can be done with freeware but it would be interesting if you show what you can do with your machines to?

[@Holocreators]

Thank you, what do you mean exactly with my machines? Would you like to see the laser scanner in action? I would love to make a video about that soon :)

[@pbnn735]

You said in previous videos your company does very high precision scanning, it sounds very interesting I think (but continue with this kind of "DIY" videos aswell... :-) ).

[@Holocreators]

​@@pbnn735 The next video will be about an ultra high definition scanner.

[@pranshooverma4511]

Great video. Wanted to know how can I stream the real-time point cloud from Azure Kinect DK to say Unity software. What should I look for to get this done

[@ahmedarnaout910]

Hello Pranshoo. Did you manage to figure it out?? if yes can you point me to the references, please?

[@Holocreators]

I assume there is a way. Looked into mixed reality recently.

[@davidtensubam]

Sir, Point Clouds is not only by 3D Scanning, it also can be developed from the Photogrammetry process if i'm not wrong.

[@Holocreators]

Hi, I guess you could also create pointclouds by manually defining the points in 3d space. You are right a 3d scanner is not required.

[@customraspi]

besides xyz, you would need a pointsize parameter. Your renderer is not state of the art. It leaves holes instead of sizing the points appropriately.

[@Holocreators]

thanks for that info. that video is already getting a little dated. maybe there are newer better software already on the market.
