[Addon] Point Cloud Visualizer


(enzyme69) #21

Great add-on! I tested with some Houdini PLY -> MeshLab -> Blender. No idea why Houdini PLY color does not work right away.

I am wondering if once the data is loaded and displayed, perhaps we can change the point size like in Meshlab?

Just wondering if I could turn this add-on into a node? For Sverchok or Animation Nodes? So that maybe the point data can be used further to generate instances?

  1. if you can provide some houdini ply i can look what is wrong with it… or houdini ply is ascii, then it will not work. addon requires binary ply
  2. well, i am not opengl master and i found only functions to draw pixel point and something called like smooth point and that’s all. i suspect meshlab draws some instanced primitive which is something out of my current knowledge. and also maybe something that can’t be done efficiently with current python api.
  3. would be better to code it from scratch. ply reader included is build for speed, it basically reads only coordinates and color. ignores everything else…

Hi there…just a little bump: any plans for a 2.8 update? Wonder how this would work in the new viewport. Hope this or similar addons will be developed as pointsclouds are more and more common nowadays.


(carbon2) #24

yes of course, if i’ll be able to do that. when python api will be finished, mac os x version gets some love from developers and i get used a bit to it…

Nice work! WOW. I’m dreaming of the day when this type of displaying of point cloud data can be editable. Would be priceless for trimming and aligning of point cloud sets.

Guys!? Do somebody knows why after installation and turning on this addon i can’t see it’s appeared in to the “N panel”? At first I thought that something wrong with Blender version or directory where it instaled. But I have same problem with default instalation proreties and with previous versions. Is it something I do incorrect? By the way openGL Lights is working well/

You need to add an helper object to the scene. Whenever you select it, a new dialog should appear in N panel.

IS this addon just showing the pcloud or also there is a way to import the point cloud with various options using the addon?


(carbon2) #30

hi, add an empty object, then panel will be visible. when you transform that empty, pointcloud transforms as well. that’s why it requires an object

just showing all vertices with rgb values from binary ply, nothing more at the moment

sounds good, thanks

carbon2, thanks for a great plugin. I love the ability to view point clouds with colour within the Blender viewport. I’m trying to export animations with this, but can’t find a way to render the point cloud to image/video files. I tried openGL and also the blender standard render. Is there anything else I can try?


(carbon2) #33

it can’t be rendered, points are drawn the same way as other addons draws custom user interface to viewport, the only way would be capture screen with some other software i guess

updated to 2.80, see first post

another update (0.4.5), added percentage of displayed points, more speed improvements and a few fixes
