Visualization of huge cloud points #23

Hello, Congratulation for this library, is very useful and easy to use. I am having problems to plot the Lidar cloud with 315.800 points. I was able to plot a segmentation of this sensor, which had only 25.688 points. Has a point limit which this function allows to view?

Thanks for all. att,

i already opened much bigger files (million of points) so this is not a software limitation. Are your data well loaded before you sent it to the viewer?

I've been hitting a similar limitation to this recently; seems like mine cuts out somewhere around 5.5m points. I know pptk should be fine with bigger point clouds than this because I've done it on a different install of pptk, but for some reason on this computer it's having trouble (not sure if maybe I have a bad build or something?) Interestingly, on mine when it does this, it seems to sometimes draw a point (or maybe all of them) at the origin.
