Description
-----------

QuikGrid is a program written for MS WINDOWS which will read in a set of
scattered data points (x, y, z) which represents a surface. The program
will generate a regular grid from this data and then display the surface
as a contour map, or as a grid viewed from an arbitrary viewpoint, with
hidden lines removed. The display may be zoomed and panned using the
left mouse button. Data about features on the display may be selected
using the right mouse button.

QuikGrid runs under MS WINDOWS 95/98/NT/2000. The display may be printed
or output as a DXF data file for input into Autocad or other programs
that support that format. The grid may be output as a series of XYZ
triplets, as a DXF 3DFACE file, as a VRML (Virtual Reality Meta Language)
file or in the ER Mapper raster format.

QuikGrid is a lean program. It is easy to use and is very fast. It will
run on modest hardware platforms. It is well suited in situations where
it is desired to have a quick look at a set of data points, for example
under field conditions where only a portable PC is available. On larger
computers it is capable of processing a large number of data points and
generating very large grids (e.g. 3 million data points to a 3000x3000
grid).

QuikGrid is self documented through it's help facility.

Installation
------------

If you are installing from a distributed .zip file unzip the file into
any temporary directory and run QGRID45.EXE 

NOTE: Version 4.5 will install by default into the file C:/Program
Files/Quikgrid, NOT C:/quikgrid . If you wish to replace a version of 
QuikGrid that is older than Version 4.4 either use the Browse button to 
direct the output to your old QuikGrid directory, or remember to delete 
the old QuikGrid directory after you install version 4.5. 

QUIKGRID IS SHAREWARE 
---------------------

You have the right to evaluate QuikGrid for as long as you require. You
are allowed to copy the QuikGrid distribution file and give it to any
other person, as long as it is not modified in any way. 

If you are putting QuikGrid to productive and useful work please
register. I reply on your support for the maintenance and enhancement of
QuikGrid. 


Distribution
------------

The evaluation version of QuikGrid may be distributed freely. It is a
fully functional version of the program if the number of data points
input to the program is less than 10,000. For more than 10,000 data
points the evaluation version will not export the generated grid, print
the display or allow the display to be copied to the clipboard.

Disclaimer
----------

Persons who are unfamiliar with machine contouring and grid generation
techniques may find articles in the June, 1992 issue of Geobyte
interesting. A quote from the conclusion of the article "Contouring: Art
or Science?" by Daniel J. Tearpock, p 43, reads "...contour maps are
interpretations - they are not absolutely correct. "
