I have created a quite large point cloud with about 800M RGB points. The exported .ply file is about 12GB large. The commercial software I used to create it can render the cloud very smoothly on my Ryzen 1800X/64GB/Geforce 1080Ti.
Now, I would like to work with this point cloud - programmatically put trajectories into it, combine multiple clouds, have more control over the point size ... Expectedly, using PyntCloud in a Jupyter Notebook failed miserably :)
Before I start learning something like Unity, are there any better suggestions? Potree maybe? Due to my lack of experience, I cannot judge yet where I would have which possibilities for working with the data.
