Description:

Purpose
This app is for calculating the convex hull envelope (boundary) for a given set of XYZ scatter points.

Installation
Download the file "Convex Hull 3D.opx", and then drag-and-drop onto the Origin workspace. An icon will appear in the Apps gallery window.
NOTE: This App uses the Qhull library. A copyright notice is included in the package.

Operation

  • Click the app icon from the Apps gallery window.
  • Pick your input XYZ data and specify output range.
  • The output column will contain the index number of boundary points and triangle patch sequence (for plotting).
  • If starting from a 3D graph, the calculated hull will be directly plotted onto the source graph.
  • Volume and Surface Area will be report to Results Log.

Updates:

v1.02: Disable graphing if user started from 2D contour plot
v1.01: Added volume and area output
