I'm writing a program that reads a point cloud and constructs an octree. From
a 6.5 MB LAS file, it constructs a 52 MB octree file, reading and writing every
block several times in the process. This takes a very long time, so I'd like
to modify the store to always allocate a buffer when there's some RAM remaining
(maybe 1/4 of the RAM available when the program started). On Linux, there's a
function sysinfo(&info) which does this, where info is a struct sysinfo, but
this function does not exist on DragonFly BSD. How can I find out the available
The reason the octree is so much bigger than the LAS file is twofold. First,
the blocks of the octree are nowhere near full; second, there are several
variants of the LAS format, and the class LasPoint has to accommodate all of
I believe in Yellow when I'm in Sweden and in Black when I'm in Wales.
