[pdal] write eigenvalues to las

[thejus kambi]

Hello,

Can anyone direct me, how to add eigenvalues in las files. I tried
following json file and it did not work.

[
{
"type":"filters.eigenvalues",
"knn":10
},
{
"type":"writers.las",
"extra_dims":"Eigenvalue0=double_t,Eigenvalue1=double_t,Eigenvalue2=double_t"
}
]

Warm Regards,
Thejus
