PointBufferPtr lvr2::subSamplePointBuffer(PointBufferPtr src, const size_t &n)

Computes a random sub-sampling of a point buffer by creating a uniform distribution over all point indices with given target size. The sub-sampling is applied to all channels in the source buffer.

Parameters:

• src – Source buffer

• n – Number of target points
