XYZL_DISPLAY_OPENGL\
Display 3D Points and Lines Using OpenGL {#xyzl_display_opengl-display-3d-points-and-lines-using-opengl align=”center”}
========================================
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: {#usage align=”center”}
- 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.
