Create Contours from Point Clouds in QGIS

This video shows how to create contour lines and polygons from point cloud data in QGIS, without interpolating first to a raster layer. Because there are no native algorithms to directly derive contours from point clouds, we'll first convert the point cloud layer to a vector layer. Next, we'll use the Contour plugin to create the contour lines and polygons.
QGIS version: 3.32 Lima
Open Data: AHN4 from geotiles.nl/
Plugin: Contour plugin

    Check the new video on filtering point clouds: kzread.info/dash/bejne/Zq2kyrqhgJyppqg.html You can either use the classification of the point or use a filter based on another attribute. Alternatively, you can also check my videos on the LiDAR Tools from the WhiteboxTools or LASTools plugins.

    @@HansvanderKwastHi, Is there a limitation (of Hardware or Software plugins) when using WhiteboxTools or LASTools? I tried to use those plugins with 700MB LiDAR data and tool was stop executing the results saying, "it cannot be executed"
