+<b>The OGSF library and NVIZ engine</b>
+<p>
+
+NVIZ (GRASS's <i>n</i>-dimensional visualization suite) was written
+by Bill Brown, Terry Baker, Mark Astley, and David Gerdes,
+U.S. Army Corps of Engineers Research Laboratories, Champaign,
+Illinois and UI GMS Laboratory, Urbana, IL in the early 1990s.
+<p>
+Original documentation was written by Terry Baker (spring 1995), and
+updated by Mark Astley, based on a document written by Bill Brown. 
+Additional design help and funding in the early 1990s by Helena
+Mitasova (CERL). Tcl/Tk support added by Terry Baker. Ported to Linux
+by Jaro Hofierka and others. Conversion from SGI IRIS GL code to
+OpenGL by Justin Hickey. Further program and documentation (2004)
+updates by Bob Covill, Tekmap Consulting. 3D volume support by Tomas
+Paudits with supervision from Jaro Hofierka and Helena Mitasova.
+Fly-through mode, thematic site attributes, and picking by Massimo
+Cuomo (ACS) with updates by Michael Barton. GRASS 6 vector support by
+Radim Blazek. Additional updates by Markus Neteler, Martin Landa, and
+Hamish Bowman.
+
+<p>
+NVIZ evolved from the earlier GRASS program <em>SG3d</em> written
+for Silicon Graphics IRIS GL by Bill Brown and Dave Gerdes at USA
+CERL, 1990-1995 and from the NVIZ Motif version written by Bill Brown
+with contributions by Terrance McGhee.
