XYZF_DISPLAY
Display 3D Points and Faces in the MATLAB Graphics Window

XYZF_DISPLAY is a MATLAB program which reads XYZF information containing a list of 3D point coordinates, and the indices of points that form faces, and displays a plot in the MATLAB graphics window.

SXYZ_VORONOI, which computes the Voronoi diagram for a set of points on a sphere, is an example of the programs whose output can be displayed by XYZF_DISPLAY.

Usage:

xyzf_display ( 'prefix' )

• 'prefix' is the common file prefix.
