QUIKGRID
3-D rendering of a surface represented by scattered data points

QuikGrid is free software released under the GNU General Public License. Version 5.4 is the most recent release. Full details are available here.


Microsoft is phasing out support for the Windows help facility (WinHLP) that QuikGrid uses. Under Windows VISTA and Windows 7 you may receive a message similar to the following when you attempt to access "Help":


"The Help for this program was created in Windows Help format, which depends on a feature that isnít included in this version of Windows. However, you can download a program that will allow you to view Help created in the Windows Help format."

Further information is available from Microsoft here.

For those who do not wish to download the Windows help facility, the help file is now available as an online html document here. You may obtain a copy for installation on your computer by downloading a .zip file here.

I am happy to provide what support I can. However, I am no longer an active user of any Microsoft Operating system, except Windows XP, which I access occasionally when required. I have no easy access to Windows Vista or Windows 7. (I have been using Linux almost exclusively for many years now).  I have no plans to produce a major new release of QuikGrid.


GENERAL DESCRIPTION

QUIKGRID is a program which will read in a set of scattered data points (x, y, z) which represents a surface. The program will generate a grid from this data and then display the surface as a contour map, or as a 3d representation. The left mouse button may be used to zoom in and pan about the display. The right mouse button may be used to display information about the generated grid coordinates and data points.

A 200 by 200 grid representing 15,000 data points may be gridded in less than 3 seconds on a 500 Mhz Pentium (actual generation times may vary depending on how the points are distributed). The grid may be displayed as a wire frame or as a hidden surface grid, optionally with colours. The grid and contour lines may be output as a DXF file. The generated grid may be output to a file as a series of XYZ triplets, in the DXF 3DFACE format or as an ER Mapper Raster Dataset. QuikGrid may be used to view 1-degree USGS DEM files.

QUIKGRID is easy to use. 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. QuikGrid is documented through its help facility.
