Круто! Большое вам спасибо за урок! Пока очень мало информации о работе с точками в блендере, и ваш урок мне очень сильно помог. P.s. Спасибо нейросетям, которые перевели мне ваш ролик😅

What scanner are you using for your capture? The walls you scanned don't seem to have the wavy lines issue I see in many RealSense 3D captures. nice work!

For this specific project I used a Leica BLK360 + A Nikon Camera for Photogrammetry, and I then merged both point clouds

Hey!:) i did my first cloud point scan and everything works except the texture. I did added the "set Material" node but beside position and radius it doesnt show the "col". Maybe my scan has not saved the texture?
@FlorentPoux4 ай бұрын
Hmmm, indeed, what you can do, is check if your point cloud has color, for example in CloudCompare?
@thibaultbunoust49544 ай бұрын
Great video. I need a advice, I created a .ply with polycam but when I import in blender ther is no Col in the spreadsheet and so I don't have color on my pointcloud. It's the same problem with .ply from Scaniverse or Postshot, maybe I missed something. Do you have an idea?
@FlorentPoux4 ай бұрын
Hey Thibault! Sure, Maybe you can explore your dataset in Python or CloudCompare, to check out your color field, and reformat it so that it is rightly taken into account for your Blender approach?

Hey Florent, Thanks for sharing your knowledge ! I'm actually trying to convert a 3dscan with this method into pointclouds, everything is fine until I want to export it in .ply format...When I export it create a .ply file, but when I re import in blender, nothing appear. I tried to convert it into vertice, but again nothing appear when I import, do you have an explanation ? I'm not familiar with these technics in Blender, and I need it to use this point cloud into TouchDesigner. Thank you in advance for your answer
@FlorentPoux3 ай бұрын
Hey Millie, thanks a lot for the kind words! Hmmm, it could be a number of reasons, But I think the first step would be to make sure that you can open your ply in another software (E.g. CloudCompare), from there, make sure you have colors, and then, re-export as .ply (binary for example). Then, import into blender and follow the tutorial, maybe adding an 'instance on point" node if things are still not visualized. This should solve your issue

@FlorentPoux8 ай бұрын
Thanks! Hmmmm, this is weird! So you meant that the .obj works but fbx not? Maybe switching the open3D version? Else check out with CloudCompare the conversion to see if this is an issue with the file or the library Open3D

Great video, thanks! I have a question for you about mesh sizes Blender can handle correctly. I have a mesh that is 1.5GB, i opened it allright, but coming to the mesh to point node, it lags and crash. I have 48GB ram,12 cores proc, and GTX1660. is that enough? I also didn't understand well the preprocessing part, is it cloudcompare you're using ?
@FlorentPoux7 ай бұрын
Hmmmm, I need to investigate why it crashes... But a first hint: handling large meshes may be the issue. Indeed, you could experiment this to see if this solves the issue: Go to cloud compare, drag and drop your 3d mesh, sample your mesh as a point cloud with the built-in function (select a number of point that is sufficient to keep your details), export as a .ply (binary) file, and then move onto following the tutorial. Does this solves your issue?
@bdamay7 ай бұрын
Thank you for the advice. In the past i used cloud compare to decimate meshes to get a reasonnable size from e57 source and export to ply, but that's all (what is reasonable size ? i didn't really investigate this further). I surely should learn this piece of software a bit more. Well, i'll try what you propose out and will let you know. Have a good day. Benoit @@FlorentPoux

Is there a way to convert the point cloud directly into a mesh inside blender, without using external software?
@FlorentPoux8 ай бұрын
Hey Michael! Thanks for the question! In blender you have to use plugins or Python directly within to get to such possibilities automatically! I put that to my agenda of videos to do ;)
@michaelhicks86038 ай бұрын
@@FlorentPoux thanks man! No stress or hurry, but that would be amazing if or when you can :) There are some nice open source option for point cloud processing including conversion to mesh and I will study these too. It would be cool to see more blender content on this subject, especially some more advanced ones that focus on accuracy retention while also optimising for real time video processing. I plan to try to proccess high density clouds from lidar survey, into models for pre-visualisation.

I can't import point cloud in blender (V. 4.0.2) there is no option in import PLY (experimental). It's visible in "Scene Collection" and shows just orange do in center. Any ideas?
@FlorentPoux8 ай бұрын
Hey Miqgio! The process is very similar though. What you can do is use the .ply importer, they now import the RGB information straight away. Thus, you can get everything from the Col attribute. The difference, si that you have to add a node "Mesh to Point" before the Set Material Node. Does this solves your issue?
