XYZ_DISPLAY_OPENGL
XYZ_DISPLAY_OPENGL,
a C++ code which
reads the name of a data file
containing a list of 3D point coordinates, reads the data,
and displays the points using OPENGL.
The program displays the data, and slowly rotates it.
Usage:
xyz_display_opengl data.txt
where
-
data.txt is a file containing a list of the XYZ coordinates
of the points to plot.
The program will open a window and display a plot of the points.
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.
