FAQ
GRD to QRT Conversion
What are GRD files?
GRD is a file extension shared by several grid formats, which store a map as a regular net of cells with one value in each cell. The best known is the Surfer grid of Golden Software, used for contour maps and 3D surfaces of elevation, geology, and other measured data, and it exists in text and binary versions. The Northwood numeric grid, created for the Vertical Mapper add-on and now associated with MapInfo, serves a similar purpose and is common in mapping and telecom planning. The R programming environment uses .grd for the header of its native raster files, with the values kept in a separate .gri file. Because the same extension covers all of these, the contents of a file, not its name, tell which one it is.
What are QRT files?
The QRT format file is associated with the QRT Ray Tracer, also referred to as Quick Ray Tracer. QRTs are uncompressed raster graphic images which contain 3D scenes for ray tracing. Although they haven't been used very frequently in past years, they can be used for various rendering applications.
