Fologram adds support for Rhino’s point cloud geometry to Grasshopper
Point clouds allow for very large collections of points to be efficiently rendered in Rhino and on your mixed reality device. Fologram outputs tracked hands and depth data as Point Cloud objects. To work with individual points in a point cloud you can use the Deconstruct Point Cloud component.
Be careful deconstructing large point clouds as these can create large numbers of individual point objects that are inefficient to display. Be especially careful deconstructing point clouds that are updating in real time!
Using point clouds for feedback
Fologram includes a Cloud Closest Point component for efficiently performing closest point calculations between a point cloud and a second arbitrary collection of points. A common use of this component is to calculate the distance from a mesh vertex to the nearest point in a point cloud in order to display how close a digital object is to its physical counterpart in mixed reality.
Creating solid meshes from point clouds
To work with point clouds in typical modelling workflows you can use the Rhino 8
Shrinkwrap command (or Grasshopper component) to create a solid mesh that wraps the point cloud object.
