#
# demo for creating GIF animation and illustrating saving images to
# file one pixel to one pixel
#
# A combination of what was animate.dem and world2.dem with the
# addition of saving the rotated image to an animated GIF.
# Requires GIF_ANIMATION
#
# History:
# - 1. 3. 2006 Dan Sebald: 1st version
# 07 Jan 2006 Ethan Merritt: Revise to assume terminal type is set by caller
#
# Caller must set terminal type.
# Example of intended use:
# set term gif animate transparent opt delay 10 size 200,200 x000000

gnuplot.rot
# A generic rotation routine for the gnuplot view. In the commands
# that load this file, the following should be defined:
#
# iteration_count: set iteration_count=0
#
# limit_iterations: if set to a nonzero value, it'll stop after that
# many iterations; if zero value, continues indefinitely
#
# xrot: the initial x rotation of the view
#
# xrot_delta: the amount to increment the x rotation for each new plot
#
# xview: function for generating x view value; for example
# xview(xrot)=(50.+30.*sin((xrot%180)/180.*pi))
#
# zrot: the initial z rotation of the view
#
# zrot_delta: the amount to increment the z rotation for each new plot
#
# zview: function for generating z view value; for example
# zview(zrot)=(60.+45.*sin(zrot/180.*pi))
