# filters.poisson¶

The Poisson filter passes data through the Point Cloud Library (PCL) Poisson surface reconstruction algorithm.

Poisson is an implementation of the method described in [Kazhdan2006].

"pipeline":[
"dense.las",
{
"type":"filters.poisson",
"depth":"8",
"point_weight":"4"
},
{
"type":"writers.las",
"filename":"thinned.las",
