Vplot.c posted to net.sources

[torben at arizona.UUCP]

Hi,
	First of all,thanks to all of you who responded to my request for
information regarding graphics on UN*X.I learned of some efforts I wasn't
previously aware of.
	Second,I was planning to mail out my version of vplot to all who
requested it individually,but as the number of requests has reached 50,
I decided that net.sources was the only appropriate way to distribute.I
mailed some of the early respondents a prerelease;those of you who got it
should replace what you got with the version I am now placing on net.sources
as there have been some small modifications.The file I am placing on
net.sources is in ar format and I presume that everybody can read it.
If anybody doesn't get net.sources and still wants a copy,let me know and
I'll mail you separately.
	You are free to make whatever use you see fit of this program.You
may redistribute it to any and all takers;all I ask is that you let me
know where you send it.The reason is that I would like to see how widespread
interest is in graphics out there and this provides a convenient way.Of
course,you get what you pay for so I assume no responsibility for what
the program does.
	I remain interested in any and all things related to graphics under
UN*X and should you come across any pointers to interesting stuff in that
area,a note would be most appreciated.
	Also,if you discover errors in my program,please let me know about
them and I'll do my best to correct them.One thing that I do not do is allow
different linestyles.They are not that easy to produce on the versatec and
making them come out right is too costly.The version of vplot you are getting
is complete in all other aspects though and conforms to plot(5).It is written
for fan-fold paper,but could easily be modified for roll-paper.Also,you should
be able to modify it to use any other bit-mapped device you may have;changing
putpicture.c should be enough.
	Lastly,I'd like to know some more about what kind of graphics are
perceived as "needed";i.e.,would you have any use fro a 3-D graphics 
program?I'm working on one for my own enjoyment,but I'd like suggestions.
Are you satisfied with CORE?So if you have an idle moment,I'd appreciate
suggestions as to how to do things.
			Have Fun,
