Hi! I need to thin out a uniform(?) point cloud where the points are spaced out evenly, the result should also be spaced out evenly. I tried the PointCloudThinner but it does not seem to do what I want. See attached pictures. The circled objects are the ones that need to be removed. I Hope I explained the problem clearly enough😊

If the points are aligned to a grid and are integers (e.g., x and y do not have decimals) then you can try this option.
The unfiltered result should contain what you want.
This works by just filtering out all the points (x or y) which are even and keeps the odd points.

Another option is to force to a raster (you could try the NumericRasteriser) here you can specify cell spacing. Just pick twice the spacing of the point cloud. Next step is the then pass the raster through a PointCloudCombiner which will turn it back into a PointCloud.
