XYZL_DISPLAY_OPENGL
Display 3D Points and Lines Using OpenGL


XYZL_DISPLAY_OPENGL is a C++ program which reads XYZL information defining 3D points and lines, and displays an image using OpenGL.

The program displays the data, and slowly rotates it.

The program SXYZ_DELAUNAY, which creates a Delaunay triangulation on a sphere, is an example of a program whose output is in the form that this program can display.

Usage:

xyzl_display_opengl prefix
reads the XYZ coordinate data in prefix.xyz and the line information in prefix.xyzl, and displays a plot of the points and lines. 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.
