Poisson filter: Colors from pointcloud are not reconstructed #4493
Description
I am using a pipeline to convert a pointcloud into a mesh.
[
{
"type" : "readers.las",
"filename": "ground_shifted.laz"
},
{
"type": "filters.poisson",
"depth": 9,
"density": true
},
{
"type":"writers.ply",
"faces":true,
"filename":"poisson.ply"
}
]
The colors in the laz pointcloud are 16bit, so rgb values are between 0 and 65535. In the output ply file, rgb values are all set to 255.
ply
format ascii 1.0

Expected behavior
Colors should be represented in the mesh file.
