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 (c) 1998 Greg Turk
