NodPlot was developped to ease the task of visualizing rapidly
properties in 3D structured meshes for Computational Fluid Dyn-
amics (CFD) research. The mesh must be 3D or more explicitly:
3 dimensions in space or 2 in space and 1 in time. 2D meshes can
be visualized simply by repeating twice the 2D data in the input
file.
The visualization is performed on a node basis, rather than a
spatial and/or temporal basis, easing the task of visualizing
complex spatial geometries in 3D.
The author can be reached by email for bug reports, comments or
code improvement suggestions at [email protected].
NodPlot was written with the cross-platform Qt libraries, which
can be obtained from http://www.troll.no. You need version 1.40
or higher.

CONSULT THE "INSTALL" FILE FOR INSTALLATION AND TEST RUN INSTRUCTIONS

==========================================================================
NOTES:
--------------------------------------------------------------------------
1. If you need to change the fonts used in nodplot because they appear too small
or too big, edit the file fonts2.h and then recompile the code
with 'make clean' and then 'make'. Then reinstall it with './Install'.
Not that this version of NodPlot does not permit the user to modify the
font sizes in the .Xresources file.
--------------------------------------------------------------------------
2. The initial values for the resolution factor, the number of scale
levels and other parameters are set in the file nplot.cpp in the
subroutine Nplot::init. Depending on how fast your machine is and
how many colors are available on your X-Display, you might like to
modify the values in this subroutine. For example, change the lines
'cv.resfact=...' and/or 'cv.scalelevels=..' according to your
needs. Note that a higher resfact will give you better looking
graphics, but will also reduce the refresh rate. A higher scalelevels
will give you more colors but not enough colors might be available
on your 8-bit X-Display which will screw up your scale.
(read note 3 on how to change your 8 bit display to 16 bits).
NOTE: the scalelevels, the resolution factor and most things initialized
in Nplot::init can be changed on the fly while running
nodplot; so you don't need to change the nplot.cpp file
unless you run this code extensively and need different
defaults..
--------------------------------------------------------------------------
3. For better performance, it is recommended that you set your
X-Window display to 16bits, and not 8 bits. This can be done
quite easily by adding the line "DefaultColorDepth 16" in
the "Screen Section" of your /etc/XF86Config file. If you have
only a 1 meg video card, add the '800x512' mode (listed below)
to have more than a 640x480 resolution. Theoretically, it might seem
that a resolution of 800x600 with 16bits per pixel could be handled by a
1meg video card, but in practice it just ain't so. The problem comes
from the accelerated X-Server which uses a multiple of 1024 pixels
horizontally (even if you require only 800), hence blowing up the card's
memory when 600 pixels are used vertically.
Modeline "800x512" 36.00 800 824 896 1024 512 513 515 592
Then, your "Screen Section" should look something like this:
Section "Screen"
Driver "svga"
Device "Trident TGUI9680 (generic)"
Monitor "My Monitor"
DefaultColorDepth 16
Subsection "Display"
Depth 16
Modes "800x512" "640x480"
ViewPort 0 0
Virtual 800 512
