Sample OPJ to download to try: 3D Triangle Patch by Specified Data Index.opj
(ORG-8141)
The technique supported in 9.1 allows user to create surface which is made of one or many triangles. It is useful for drawing 3-D polygons of arbitrary shape
In previous version, Origin automatically determines how to connect the vertices. Origin 9.1 introduce 3D Triangle Patch by Specified Data Index, which allows you to specify the order of vertice connection by the index data column
To make such patch. we should prepare a worksheet with data form, X Y Z Index.
