IAC OrthogonalViewer Project
----------------------------

This directory ( iac_proj/orthview/ ) contains all the V code, source 
code, HTML documentation, and installation information for the IAC 
module "OrthogonalViewer".

The directory should be placed into your existing project directory, which
should already contain the IAC Project File structure, i.e., the iac_proj/,
iac_lib/ and v/ directories.

The file INSTALL contains information on how to edit the existing IAC
files: a single line addition to the iac_proj/iac_proj.v file, to add the
new OrthogonalViewer project, and a single line addition to an iac_lib/
file (in this instance data_io.v) to add a link to the User Macro from the 
new top-level IAC library page.

Once the files have been correctly installed, the low-level module of
the new project may be compiled. If you opt to leave the process
unspecified, it will by default use the "express" process. Doing so
means the module may be compiled by using one of the following
commands in the top-level directory of your project (whilst
AVS/Express is not running):

	base -comp_proc express -exit

or	make -f express.mk

	Using the 'make' command, requires that the express.mk file
already exists, and has been updated accordingly.

	If you modify the OrthogonalViewer project, and specify the
process as "user" or another user-defined process, then the module may
be compiled without having to exit the AVS/Express application. Use
the following command in the VCP to compile the module:

	$compile IAC_PROJ.OrthogonalViewer.OrthogonalViewerMods

	Users of the Developer's Edition may select the module in the
relevant Templates library, and choose 'compile' from the Project
menu.

Files
-----

The following files can be found in the iac_proj/orthview/ directory.

INSTALL			Contains installation instructions for editing the iac_proj.v
				and iac_lib/data_io.v file. This file should not be edited as
				the future installation script will use this file.

orthview.v		Creates the IAC_PROJ.OrthogonalViewer library.

oviewmod.v		Creates the OrthogonalViewerMods library containing the 
				low-level support modules box_value, copy_on_modify and the
				parameter group OrthogonalViewerParams.

oviewmac.v		Creates the OrthogonalViewerMacs library containing the 
				high-level macros OrthoScene, OrthogonalViewerUI and 
				OrthogonalViewer. It also contains the support macros 
				get_position, ChangeDatarange, ChangeZoom, DrawCross2D, 
				globalUI, localUI which are used by the high level macros.

oviewapp.v		Creates the OrthogonalViewerApps library containing the examle 
				applications OrthogonalViewerSingleEg and OrthogonalViewerMultiEg.
			
cmodify.cxx		C++ source code for the copy_on_modify module.

translice.c		C source code for the TransSliceCut module.

orthview.html	HTML documentation for the OrthogonalViewer module.
orthview2.html	HTML documentation for the OrthogonalViewer2 module.

Generated Files
---------------

When the project is compiled, the following files will be generated. Once
completed, you may safely remove these files; any future recompilations
will regenerate these files.

gen.h			AVS/Express generated C++ header file.

gen.cxx			AVS/Express generated C++ source file.

cmodify.o		Intermediate object file.

translice.o		Intermediate object file.
