[osg-users] Massive Point Cloud rendering

[Bruno Oliveira]

I found out what I was looking for,

https://github.com/adasta/osgpcl

However, this depends on octrees from PCL. I'll think on some alternative
using OSG only. Does OSG implement anything like this?

Robert: Thank you for your tips. I will make sure to be more specific in
the following posts. However, let me just stress that I did not go into
much detail because I did not want to solve any specific problem, I just
wanted to state tthat rendering a huge point cloud at once is slow and
therefore I needed to research for some optimizations.
What I did with the OSG PagedLOD was to convert a ply point cloud with 70
million points to some .ive file, with "./osgpagedlod cloud.ply", and then
trying to view it with osgviewer, "osgviewer output.ive"
