Instance Method Details

#points ⇒ Array<Array>

Gathers all points from the associated layer. If GridderOptions#input_clipping_geometry is set, it filters out any points that fall within that geometry. This is really just indented for internal use, but is being left public just in case it serves some benefit for debugging.

Returns:

  • (Array<Array>)
