Re: Subsample a point cloud at specified points/regions

Thanks Daniel, but I guess don't quite understand what the sigma parameter is. It seems like the output is still just an average, but weighted, as per "Compute a weighted average of the neighbors SF values" when I hover on the "Normal distribution" option. I need to calculate the...

Re: Subsample a point cloud at specified points/regions

Hi Daniel, one more thing. Would it be possible to add in standard deviation and n or count to "interpolate from another entity" under interpolation algorithm? Currently the options are Average, Median, and Normal distribution. It would just be nice to have more stats so I can make error b...

Re: Subsample a point cloud at specified points/regions

Hey everybody, I think I figured out how to do this. I interpolated my dense point cloud onto my sparse point cloud. I used the Radius (sphere) option with average interpolation. This gave me a SF in the sparse point cloud where the scalars were averages of all the dense points that fell within 10 m...

Re: Subsample a point cloud at specified points/regions

So my extracted data would look something like this: X1 (sparse cloud), Y1 (sparse cloud), Z1 (sparse cloud), Scalar at point 1 (sparse cloud), X1 (dense cloud), Y1 (dense cloud), Z1 (dense cloud), Scalar at point 1 (dense cloud) X1 (sparse cloud), Y1 (sparse cloud), Z1 (sparse cloud), Scalar at poi...

Re: Subsample a point cloud at specified points/regions

Thank you, Daniel. I see this is quite simple to do. However, I ultimately would like to plot each of the sparse point's attached data (avg 3 nearest neighbor distance) against that points corresponding strain data in the other cloud (which I will average). Would it be possible to index the points i...

Subsample a point cloud at specified points/regions

Hello, I have two point clouds. One point cloud is well populated and dense, each point's magnitude represents strain. The other point cloud is much less populated and dense, each point's magnitude represents the average 3 nearest neighbor value (also spatially it is the center of an embryonic heart...
