This operator lets you write an external program/script that reads in
.geo or .bgeo formatted data|/io/geo]
(Houdini automatically detects the format), manipulates the data,
and writes out modified
(set using the Output format parameter).
Despite its name, the
unix command works on non-UNIX operating
Houdini includes a number of standalone utilities
in $HFS/bin (starting with
g) that process geometry data and
support all geometry types.
Often the standalone utilities included with Houdini follow a
convention where filenames prefixed with
read from standard input or write to standard output, instead of
reading from/writing to a file. For example, you can use gconvert
with this node by calling it as
gconvert stdin.geo stdout.geo.
You can use an external process to generate geometry rather than filtering it by ignoring the input and simply having the external program write out the geometry you want to generate.
The command string to execute.
Controls the format Houdini sends to the external process,
.bgeo. This is not the output format written by
the external program (Houdini automatically detects that).
Write out .geo data to the external process.
Write out .bgeo data to the external process.
