class mp2p_icp_filters::FilterDecimateVoxels

Overview

Builds a new layer with a decimated version of one or more input layers, merging their contents.

This builds a voxel grid from the input point cloud, and then takes either, the mean of the points in the voxel, or one of the points picked at random, depending on the parameter decimate_method.

If the given output pointcloud layer already exists, new points will be appended, without clearing the former contents.

If the parameter flatten_to is defined, this filter will also “flatten” or “summarize” the 3D points into a 2D planar (constant height z) cloud.

Not compatible with calling from different threads simultaneously for different input point clouds. Use independent instances for each thread if needed.
