XYZF_DISPLAY_OPENGL
Display 3D Points and Faces Using OpenGL


XYZF_DISPLAY_OPENGL is a C++ program which reads XYZF information defining 3D points and faces, and displays an image using OPENGL.

The program displays the data, and slowly rotates it.

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_OPENGL.

Usage:

xyzf_display_opengl prefix
where reads the XYZ coordinate data in prefix.xyz and the face information in prefix.xyzf, and displays a plot of the points and faces. The image will slowly rotate. Successive mouse clicks alternate the axis of rotation from the X, to the Y, to the Z axis and back again.
