The data block records for the
triangle vertices are contained within
the GSI file in sets of three. There is
one block for each vertex of each
triangle. Data block for triangle vertex
11....+00000907 71....+TRI00001 81..10+21000000 82..10+50996000 83..10+00100000
WI11 Point identification, ignored by the application.
WI71 Triangle number, indicates triangle the coordinates belong to.
WI81 Easting of the triangle vertex.
WI82 Northing of the triangle vertex.
WI83 Elevation of the triangle vertex.
The program cannot calculate the model from coordinate
lists. The coordinates must be sorted by triangles. That is, three
coordinate blocks with the same triangle number must be found
together in the file. The vertices do not have to be sorted in any
other way.
