XYL_DISPLAY_OPENGL\ Display 2D Points and Lines Using OpenGL {#xyl_display_opengl-display-2d-points-and-lines-using-opengl align=”center”} ========================================


XYL_DISPLAY_OPENGL is a C++ program which reads XYL information defining points and lines in 2D, and draws a picture using OPENGL.

The point and line information is stored in a pair of files, called the XYL format. Essentially, the first file stores a list of point coordinates, and the second lists point indices to be connected in lines.

Usage: {#usage align=”center”}

xyl_display_opengl prefix

where

reads the point coordinate data from prefix.xy and the point index lists from prefix.xyl and displays a plot of the points and lines.
