Hi everybody,
I am starting with PDAL step by step,
I read an las file that I display with osg that work pretty well,
I want now make some optimization for loading and reloading my scene,
My file testing is las with 25 000 000 points so I use:
One reader, on which I use decimation filter, then Crop filter.
All this step are quick, but when I use sequentialIterator and read function
I can take a coffee break.
That is a big problem for me, cause I want to reload my scene with different
decimation factor or different Bounds.
And each time all las is read.
Is there any method for read only a part of file?
Any way to produced spatial index ?
Regards
