Subject: spatial search code sought
Date: 19 Nov 92 20:32:55 GMT
Followup-To: poster

I'm looking for some public-domain C or C++ code to do
spatial searches.  More specifically, I have a set of 3-D
points to be checked against a position.  I want to determine
if any of the points are within a specified radius of the 
position, and if so, return either the list of those within 
range or ANY single point within range (either one will do).
I'm going to do this repeatedly with the same points (but 
different locations); I'm willing to pay for some preprocessing 
to get rapid search (I need to do this search very quickly)
so some sort of spatial subdivision algorithm might be 
appropriate.  Note that this is essentially a collision 
detection or 3-D picking problem.

I want to find running,tested code (I know some of the
appropriate algorithms and where to go to find others - what
I need is an implementation).  Ideally, I'd like a set of
C++ classes (or C functions) that includes methods such as:
   
    - add a point to the search list (updating search datastructure)
    - delete a point from the search list
    - perform a search, returning hit list (or single hit)
    - copy the search structure

If you have fairly clean, easy-to-use, documented code (isn't it
all?) that you'd be willing to pass along, I'd be deeply in your
debt.

Thanks,

Sorry, I know that a very similar problem was just subbject of 
discussion in this group, but I still don't get it. 

I know how to maake contour plots or how to find out which contour
lines are actually plotted. What I can't figure out is how to
control these parameters. Is there any way to tell gnuplot to plot

- either contour lines from z1 to z2 in steps of z3
- or the following list of contours: z1,z2,z3...

In other words, can I manipulate maximum and minimum z-values
(not just print them out). Note that there is no way for me
to do this in the data file, since the data are very irregular.


Thanks for any answer, posted or by e-mail to hasch@krypton.chem.QueensU.CA

I would like to add another question concerning contouring with GNUPLOT.
My problem is to get contours of logarithmic spacing while plotting the
data linear (plotting log data with linear contour spacing would be easy
if there weren't negative values...). So, the problem is how to tell
GNUPLOT using contour levels l(k) = lzero*f^k [k,0,n-1]i where f is some
factor?

Date: Fri, 20 Nov 1992 14:34:49 EST
From: khera@cs.duke.edu (Vivek Khera)
Newsgroups: comp.graphics.gnuplot
i had to make some hacks to get gnuplot 3.2 to compile on an Alpha machine
running OSF/1 from DEC.  basically i started with the dec/ultrix setup and
changed a couple of things.  here's the additions to the makefile.unx file:


DEC_OSF_FLAGS = \
           CFLAGS="$(COPTS) $(OPTIONS) -DNOGAMMA" \
           LIBS="$(LIBS)" X11FLAGS="$(X11FLAGS)" X11INCLUDES="$(X11INCLUDES)" \
           X11LIBS="$(X11LIBS)" \
           PLOTXFLAG="$(PLOTXFLAG)" GNUPLOT_X11=$(GNUPLOT_X11) \
           X11INSTALL="$(X11INSTALL)" \
           TERMFLAGS="$(TERMFLAGS)"


dec_osf:
	$(MAKE) $(MFLAGS) $(MY_FLAGS) $(DEC_OSF_FLAGS)      $(TARGET)

and everywhere the function complex() is used and the <math.h> header is
included, i had to do something like this:

#define complex XXX
#include <math.h>
#undef complex

since the DEC OSF/1 math.h header has a typedef for the word "complex":

  typedef struct { double r, i; } complex;

which causes all kinds of problems.  maybe the complex() function in gnuplot
should be renamed?  i'm not sure what kind of fix could be made for this.

also, the make install target can't do a "strip" on the executables for some
reason, so i had to take that out.

with these changes, the build went quite smoothly.  everything tests out
fine, and is quite fast, i might add.

i think since these machines are starting to become available, you might
want to add some of these notes (if not the fixes themselves) to the 3.3
release so people can get things working.

 10.0     1.5        100

 15.0     1.5        100
 15.0     2.0        90

What I want to draw is a 3-d surface with grid lines. The gnuplot command I
typed were:    set term x11
               set parametric
               splot "datafile" w linesp
Instead, I got a plot in which each two consecutive data points are connected
by a line. It is not a good display at all. Is there some way to get the grid
surface or I missed something?

From: mike@wavefront.wti.com
Newsgroups: comp.graphics.gnuplot
Wavefront Technologies sells a 3D data analysis and presentation
software package called the Data Visualizer.  It has extensive
interactive 3D capabilities, but very little function in the
plotting area.  

In its next release a communication link has been built between
the Data Visualizer and gnuplot.  With it, all sorts of permutations
of the 3D data can be extracted and exported for plotting.

Wavefront will include this communication link as part of its 
standard software release.  It is given in source code form such
that the user will have a working example in the event that another
plotting package is preferred.

In reviewing the copywrite information on gnuplot it is stated that
the code can be used freely if it is neither altered nor sold.
Wavefront is interested in including gunplot with its standard 
offering.  There will be no additional charge for it, and doing 
so would make it available to those who do not have Internet access 
to acquire it themselves.

Is there a contact at this e-mail address that can give us information
on the steps necessary to obtain this right?

From the manpage:

          Gnuplot provides two terminal types (x11 and X11) for use
          with X servers. The X11 terminal type provides differing
          colors as well as shapes for the points plotting style. The
          two types are otherwise identical.

So 'set term X11' (capital X) will give you multi-color points. This
will not be necessary with gnuplot 3.3.

Subject: Several gnuplot_x11 windows on the screen?
Newsgroups: comp.graphics.gnuplot
I use gnuplot 3.2 to display NMR spectra. The > 32 k points/plot make
it very attractive to zoom in on several interesting spectral regions.
Hence I would like to keep several expansions (gnuplot_x11 windows) on
the screen.

I wrote a program which does all the numerical stuff and for display
purposes writes data files and various gnuplot command files like:

78> cat gnuplot_cmds
 ...
 plot "SQPhase" t" DQ phases" w errorbars,\
      "SQPLin" t" -1.334337  +.023084*f" w lines,\
      "SQPQuad" t" -1.431 +.0257*f-.000016*f^2" w lines,\
      "DQPhase" t" Shift phases" w errorbars,\
      "DQPLin" t"  3.918367  +.004473*f" w lines,\
      "DQPQuad" t"  3.636 +.0238*f-.000276*f^2" w lines
 pause 10000000

and then calls "gnuplot gnuplot_cmds&" as often as necessary (...time
for a coffee break). No, I don't like a "pause 3600". I would like to
remove the gnuplot windows myself when I am sure I don't need them any
more.  Well, the command file works except that the most convenient
way to get rid of these windows is to use the window manager (mwm,
RS/6000-320, AIX 3.2, X11R4) to close them.  That kills the
"gnuplot_x11" processes but the "gnuplot" processes survive and fill
up the process table:

ps augx | egrep gnuplot
xccbond  11765  0.0  1.0  180  264  pts/2 S    18:48:27  0:00 gnuplot gnuplot_c
xccbond  14380  0.0  1.0  184  264      - S    19:01:49  0:00 gnuplot gnuplot_c
 ...

Is there a way to initiate the display of several gnuplot display
windows simultaneously from another program without producing all
these dead processes when the display windows get closed?

Thanks

function PCL_PORT_init in term/hpgl.trm sets the paper size to
"Letter".  I am in Europe where the sane default is A4. Is it
acceptable to change the file, or should I create an alternative
output terminal type?

By the way, I also had trouble compiling as the bsd4.2 library I have
uses index rather than strchr.  I could have used the other C system,
but that only uses strict ANSI C libraries.

I am sorry if this is a simple Q or has been answered before.
With that apology;

I want to use Gnuplot outputs in a paper but am unable to change the 
fonts used in the labels (i.e. darken the labels etc.). Is there any way
of doing this ?

Thank you in advance

X11 support only works with Unix systems in the the 3.2 release. (Hint:
the makefile that builds it is called makefile.unx;-) Jehavi Bourvine
contributed VMS X11 support which will be in the 3.3 release.

X11 windows work fine in the release I copied from ames.
However nowhere is written that under VMS one has to define:
$ gnuplot_x11 :== "run disk:[directory]gnuplot_x11"
Then you set term x11 and it WORKS!

	f(x) = sqrt(1-x*x)
	plot [-1:1] f(x),-f(x)
	pause -1 "Hit return to continue"

No.
