Join Chris Reilly for an in-depth discussion in this video Generating polygonal mesh data from point clouds, part of Learning Grasshopper.
…Grasshopper has some very interesting components for…generating polygonal mesh data for point clouds.…These tools are located under Mesh > Triangulation in the Component panel.…Point clouds quite simply are groups of points in space.…Now you might get a point cloud from an external source,…like say the result of 3D scanning an object or building, or…you might manually draw a bunch of points in Rhino into a point cloud.…Or like in this example,…you might generate a group of points from right inside of Grasshopper.…So here we got a definition that's generating a cloud of…random points in three dimensional space.…So let's quickly walk through how this definition is set up.…
Here I have two constructs domain components.…One for the XY domain which determines the horizontal span of the point cloud, and…one for the Z domain which controls the vertical span of the point cloud.…Below that I have an integer slider that sets the total number of…points to generate.…So for each one of the 100 points I'm asking for,…
