Hey Guys, Any idea why the Add On will not apear in blend 2.83?
No error message. Looks like everything worked.

"Modules Installed () from 'C:\Users\*******\Downloads\bpy-master.zip' into 'C:\Users\********\AppData\Roaming\Blender Foundation\Blender\2.83\scripts\addons'"

Thanks,
J

Hi, I wonder is the only option to test Point Cloud Visualiser to buy it via blender market?
in the python file you start with lines that it is a free software - https://raw.githubusercontent.com/uhlik/bpy/master/space_view3d_point_cloud_visualizer.py, but maybe I miss it somehow, how to download addon to test it.
If it will work well, then of course I would buy it to say thank you for your effort.
Will be glad for answer.

Hey,
Amazing tool, thank you.
I'm having an issue importing my XML to blender.
I get the bounding box but not the cameras.

I'm pretty sure it has something to do with my export. Any ideas? Many thanks

Hi There,
Thanks for this tool I have been loooking for this for so long!
Thanks
J

Hello Everybody
So I have a file of a model with 120 mb but the pointcloud visualizer is only showing 3.7 mb of it - can I change this value to the max somewhere?

Hey, complete git-hub noob here.

I was looking for a ply.visualizer/renderer pretty long and your addon seems to be amazing!
But i have real troubles to get the rendering engine to work. Honestly only because i'm a ultranoob in working with third-party plugins..
I tried to it like you mention it in the how-to-file but i dont get where i should find that "properties" button
Sorry for my noobish question haha

Hello

Thank you for your great plugin. I try to get it to work for blender 2.8. It works all well, but it seems like the ply files are not supported. do you have anywhere an working ply file as an example?
This would help so much

Thank you very much

Regards

I installed the add-on and was able to load a ply file without issue.
However the point cloud is not visible when doing a render using Cycles. Do you have any idea why ?

I use Blender v2.90 and bpy v0.9.30 on Windows 10.

Hey,
first of all: thank you for this amazing addon.
Is it possible to use this addon in conjunction with "Render/OpenGL Render Image" or "Render/OpenGL Render Animation"?
Currently, I see the imported point clouds only in the 3D View. When pressing one of the buttons above, my scene is rendered without the point cloud.

Hello
GREAT, i really need this thing!
Thank you!
Can you more improove this addon? I mean trigger checkbox must be ready at hand, may be at header near blender logo on top.
What do you think?

I render point cloud files in blender all right, but when I render in a script with the python command, the command reported an error
For example, "PCVManager.load_ply_to_cache(None, bpy.context)" is used to load ply file.
PCVManager.render( ? )
Is this command used for rendering? if it is, I want to know what the parameters of this command should be.
Thank you!

Hi, i have some problems with render, the picture is black and there is nothing on it.
I tried to change the light but nothing worked, i don't know what else to do.
I have the latest official version of blender.

Hi,

first, thank you for great plugin!

I have some feature/improvements ideas:

• progress-bar during rendering animation
• rendering time counter
• render above 10000x10000 resolution

thanks

First of all, thanks you so much for this amazing plugin.

I run into an issue with the blender 2.8 version, the pointcloud can't be draw into the scene. Have you an idea of what can cause this problem ?

Hello,
I am trying to work with your PCV add-on, I have the blender version 2.92. on mac, but from some reason, when I hit render (single image or animation) the outcome png files are only grey (blank), no image shows up - I am a complete beginner with blender, but I followed all instructions I could find (attached the cloud to empty object, set active camera seeing the cloud), created some simple movement of the camera, I can't figure out what I am doing wrong, it must be some stupid mistake :).

When I try to activate the carbon_tools.py addon I get this error:

I'm not an expert with python. What does the stuff: SomethingProperty(x="yoda", y="ceasar", ) syntax do? Is this something that only works in Python 2.7?

Hello,

I have a series of several PLY files I'd like to load into Blender using the Point Cloud Viewer and then convert to meshes. Would it be possible to get some hints on how to script this? I saw the example you wrote using PCVOverseer but I wasn't able to get that to read a PLY file.

Thanks!

I wonder how I can load mutiple .ply files to Point Cloud Visualizer and combine them?

I am adding your point cloud visualiser to https://wiki.osarch.org/index.php?title=AEC_Free_Software_directory - is it possible to know what open-source license your code is under?

Cheers :) Your project is super valuable for as-built verification for BIM models in the construction industry!

Thanks for the updated for Blender 2.8x version, this addon is very powerful and easy to use.

I can see there is a way to generate point cloud from mesh, but I wonder if we can "remesh" from point cloud into surface mesh kind of like MeshLab?

Good afternoon! Your add-on Point Cloud Visualizer is amazing but I try animate a presentation of the true models with cloud points references and do the render is a problem, no for the points. The original poly model that I have aligned isn't rendered, neither after delete the empty used for import the point cloud. Any suggestion? Thank you. Apologize for my english.

I wonder how to use blender itself instead of PCV to render the animation video of the point cloud visualize by PCV?

Hi, (first, thanks! awesome tools!)

I have just enabled this addon for Blender 2.82, when I open a .ply file from the PCV menu I get error:

too many values to unpack (expected 3)
No vertices loaded from file at C:\Users...\pointcloud.ply

There's no tracback information either, only a single print statement so I can't even begin to debug the error because I have no idea which line or python file to check.

I think my .ply format is correct, but there are no example .ply files in this project to confirm that the addon is even working. Could you please add example color .ply to help new users figure out how this addon works?

Also I have binary .ply files that I can import normally as simple .ply in Blender without issue, but when I try to import same file using this addon I get an error:

'ascii' codec can't decode byte 0xe9 in position 1: ordinal not in range(128)
No vertices loaded from file at C:\Users...\pointcloud_binary.ply

Is there a way to bake point cloud colours to created mesh using for example emission?

Hey Guys,
When i try to generate points using:
Souce- Surface
Algo- Weighted randow
colors-UV texture
I get this message 'ShaderNodeBsdfPrincipled' object has no attribute 'image'
Any ideas how to resolve this ?
Thanks,
J

I exported a ply file from Open3D library. This is what I saw after importing to blender:

After lots of time struggling with Open3D, I found just by clicking Enabling Edit Mode, it will be fixed:

Hi there. I was wondering, as my title says if you know how to convert all the imported point clouds to isospheres with vertex colors using script. I want the converted objects to inherit the same keyframes for animation.
I'm very new to blender and python so any help would be very appreaciated.

Best wishes.

Hello,
I want to import a .csv file and am unable to find the import sub-panel described in the documentation:

Does the PCV version I just downloaded no longer have that ability? I assume there should be an "Import" drop down

Thank you!

I use code to blender a single object, but I set a camera location use 'cam.location = (0, 1, 0.6)'. So if I want to know its rotation matrix and t vector. what should I do?

Sorry to bother.

I downloaded the zip and installed addon from file as always, but when I try and search for it to activate it I doesn't show up. Other people type Point Cloud Visualizer and when I try that nothing shows up

In Blender 2.80 I get an error when I try to render points with the Point Cloud Visualizer:
'Context' object has no attribute 'evaluated_depsgraph_get'

Reading the documentation section on the API seems to only cover loading custom point clouds, rather than from ply files. I am attempting to register many point clouds together and it would be easier to load them all at once, rather than create object, navigate to ply file and add, change display %; for every ply file. Could you possibly add a way to do this, or describe how to automate this process. I can get it to the point were the objects are created and the PLY file is "attached" to each object, but they don't draw the clouds.

`import bpy
import bmesh

for i in range(18):
bpy.ops.mesh.primitive_plane_add(enter_editmode=False, location=(0, 0, 0))
bpy.context.object.name = "cloud." + str(i + 1).zfill(3)

o = bpy.context.object.point_cloud_visualizer
o.load.filepath = "D:\Scan Data\200794_SI\200764_SI." + str(i + 1) + ".ply"
o.display.percentage = 25`

Hi,
I read the readme. But it only show how to edit existing point clouds. Is there any way to create point clouds ?

For example at position ( 1,1,1) create a point with color ( 34,123,123) rgb ?

To Whom It May Concern:

I can visualize (i.e., draw) the attached .ply file without problems but I cannot convert it to cubes or ico spheres, etc., without errors:

bpy.ops.object.delete(use_global=False)
Deleted 1 object(s)
bpy.ops.object.empty_add(type='PLAIN_AXES', location=(0, 0, 0))
bpy.context.space_data.recent_folders_active = 1
bpy.context.object.point_cloud_visualizer.mesh_type = 'ICOSPHERE'

Thanks for your attention to this problem.

I've added a proposal to enhance Blender's OpenGL renderer, such that it renders the full 3D View including points drawn with GPU module to disk.

I'm posting this here, since this feature would be beneficial for users of the Point Cloud Visualizer as well. You can vote for the proposal here. If you think this is the wrong place this information, feel free to close this issue.

Hi

I want to render a sequence of .plys using cycles (since I want to render other objects in the scene as well). I am using ver. 0.9.x with blender 2.8a. Can you guide me on how to script the following steps using the python api?

1. Load the colored pointcloud .ply
2. Convert to mesh using ico-sphere with mesh instance size 0.05
3. Enable vertex color in Base Color and Emission attributes in material properties of the generated mesh (I am not able to render the per-vertex color without explicitly setting this).

I am new to blender so any help would be appreciated.
Thanks!

Hi Uhlik, just wondering with Blender 2.80 is almost out of beta, would it be possible to revisit your add-on and add special feature for:

• Loading sequence of PLY point cloud data
• Ability to see and pass point cloud data with bpy (for use in Animation Nodes, Sverchok, etc)....

Thanks again!

I am happy to donate for this~

Hi! Thanks for a great add-on. Newbie question - I have everything working well but my renders export with an opaque grey background as opposed to a transparent PNG. Am I missing something obvious?

Hey,

Is there anyway to convert my complete sequence to mesh without needing to go through each frame of the sequence and converting?

Hi there,

Tried to install your import Agisoft cameras xml addon in Blender 2.93.4m it will enable, but I cannot see it listed in the scene menu?

Is it not compatible above 2.80?

Many thanks.

Is it possible to map uv with nodes with PCV? Perhaps input the ply file to a node to change the RGB values and finally export to the PCV tool?

Colorize option in project filter works fine with and I'd need to do reverse:
Write the (empty image) texture base on UV Map of a target mesh.
Is it possible to implement or help me do it?

I manage to get the Point Cloud Visualizer addon works great in Blender 2.79 but a couple of questions arise:

• Can we load a sequence of PLY or .... limited to only one at a time?
• Is it possible to source and query this loaded PLY data using BPY? I wanted to use it for other purpose.

Thanks!

Converting LAS (Mobile Lidar Scanner) to PLY files (Binary) using cloud compare. Having issues with Missing Vertex Normals when I click Draw....Am I missing something here

?

Do I need GPU for this to work? I tested on Blender 2.80 Mac CPU only...
