Geometry Manipulation
---------------------
flipply - flip the orientation of faces
normalsply - compute surface normal vectors at vertices
xformply - transform vertices (translation, scale, rotation)
Create PLY Files
----------------
platoply - make any of the five Platonic solids
sphereply - create a sphere
File Conversion
---------------
ply2ascii - convert polygon file to ASCII version
ply2binary - convert polygon file to binary version
ply2iv - convert to Inventor file format
obj2ply - convert from Wavefront .obj format
Information About Files
-----------------------
boundply - find bounding box of object and re-position if desired
headply - print out the entire file header
Support Routines
----------------
ply.c - layout grammar parsing and file I/O for geometry filters
adjacency_module.c - determining ajacency between vertices and faces

Introduction
------------
This package contains a collection of geometry filters-- programs that
are for manipulating polgonal representations for 3D graphical objects.
This source code is undergoing revision, and I expect that a new
version of the code, together with many more filters, will be
available shortly.
Support Requirements
--------------------
These geometry filters have been developed on a Silicon Graphics
workstation using the native C compiler. The code may very well run
unmodified on other platforms but this has not yet been verified.
You will need some Inventor or VRML viewer to look at the models that
are created using these filters. The programs "ivview" and "SceneViewer"
are such programs that are shipped with SGI workstations.
Compiling
---------
The command "make all" should compile and link all of the geometry filters.
Documentation
-------------
Manual pages have not yet been prepared for the filters. However, most
programs will print out a simple usage line when invoked with the
option "--", such as "platoply --".
Below is the documentation as it exists now. The most important file
to test out the code is EXAMPLES.txt.
ALL_FILTERS.txt - one-line descriptions of all the geometry filters
PLY_FILES.txt - details about the PLY geometry file format
README.txt - the file you are reading
cube.ply - a cube in the PLY file format
flipply.c - heavily commented read_file() and write_file() routines
to illustrate the support routines for file I/O
