anytooff(1gv)anytooff(1gv)NAME
anytooff - filter to convert a (set of) geomview data file(s) containing any geomview primitives into a single polylist.
SYNOPSIS
anytooff [filename ...]
DESCRIPTION
Anytooff reads OOGL geometry data (from the given files, if any, otherwise from standard input) and outputs the new polylist (in OFF for-
mat) to standard output. Offcombine is a synonym for anytooff.
BUGS
In converting a list object, anytooff uses PLCombine(3) to merge the members of the list. PLCombine(3) has certain limitations with regard
to the way in handles color and normal data; see its manual page for details.
When vector objects are switched into polylists, they are transformed into polygons with two vertices. The faces of the polygons are the
same color as the given vectors, but the edges of the polygons, which are their only visible aspect, have no color.

AnyToPL - convert an arbitrary geom to a polylist (OFF file format)
SYNOPSIS
#include "geomutil.h"
Geom *AnyToPL(Geom *, Transform);
DESCRIPTION
AnyToPL() takes any geom as an arguement. It then returns a polylist object which is geometrically identical to the original geom. The
transform argument is the transform applied to the entire object; it should generally be set to TM_IDENTITY when AnyToPL() is first called.
Geometric objects are handled in the following ways:
Polylists: A transformed copy of the original is returned.
Bezier: The object is rediced if necessary, then handled as a mesh object.
Quad: The object is directly transformed into a new polylist.
Mesh: The object is directly transformed into a new polylist, with extra polygons added to do the wrapping if necessary.
Vect: The object is converted into a polylist containing a 2-gon for every segment in the original vector object. The colors of the faces
are the same as the colors of the original object, but this generally is irrelevant since the faces are not visible. Note that edge visi-
bility must be enabled for an object which has been converted from a vect to a polylist to be visible in geomview.
List: AnyToPL() is called recursively and the resultant polylists are combined using PLCombine(3). Inst: AnyToPL() is called recursively
with a new transformation matrix. The resultant polylists are combined using PLCombine(3).
No effort is made to eliminate identical vertices. However, no extraneous repeated vertexes should be created. The resultant polylist
should have the same number of vertexes as the original object.
LINKING
AnyToPL() is part of the geomutil library; see geomutil(3) for information on how to link your program with this library.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()

The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
