Extended View Toolkit is an abstraction library for PureData towards
panoramic imagery creation and projection mapping.


Description
-----------

Extended View Toolkit is a set of abstractions for combining multiple
video or image sources into a panoramic image and for projection
setups with multiple projectors or projection environments with
challenging geometric forms, better known as video mapping.

Multiple input media (e.g. camera input, video files, image files,
3D renderings) can be processed. It is possible to create
imagery or video by either stitching multiple inputs to one continuous,
or by unwrapping a 360-degree image taken with a special optical lens
system. Such processed media input can then be projected onto even
irregular shaped surfaces. It is possible to blend smoothly between
multiple projectors, to create seamless immersive media environments.

Extended View Toolkit was originally created at the "Institute for Electronic
Music and Acoustics"/Graz within the CO-ME-DI-A project, lead by
Winfried Ritsch for the art installation "Extended View" by Peter Venus.

The CO-ME-DI-A project was supported by the Education, Audiovisual &
Culture Executive Agency (EACEA) of the European Comission for
the period 2007 - 2010 (http://www.comedia.eu.org/).


Getting started
---------------

For an abstracion overview, open "01_ev_module_list.pd".
Go through the examples, to learn about the possibilities of the toolkit.
There are also individual help-patches for most of the modules.

The abstractions are divided into groups by folders:

"ev-in" abstractions for media input,
i.e. video files, image files or camera input.
"ev-main" general abstractions of the toolkit.
"ev-pano" panoramic image or video creation
"ev-pro" abstractions for video projection mapping.
"ev-glsl" abstractions to load OpenGL shaders
(contains subfolder with some shader files).

There are also folders for additional files:

"data" contains the state-saving data of the example patches.
"media" contains media files, like videos or images.
"libs" contains external libraries that are used by the toolkit.


Requirements
------------

__Software:__
* PureData or Pd-extended (http://puredata.info/downloads)
* Gem 0.92.3 or higher
(included in Pd-extended or to be downloaded from http://gem.iem.at)
* For OSC support, additional libraries may be nessecary
(e.g. mrpeach, iemnet; included in Pd-extended)

__Operating System:__
The abstractions have been tested on Linux (Debian/Ubuntu),
Mac OSX 10.6/10.7 and Microsoft Windows 7.

__Hardware:__
Recent graphics hardware required to have access to full OpenGL
capabilities of GEM

__Following problems have to be considered:__
Connecting more than one USB camera of the same type to a Windows
or Mac Computer requires lots of tweaking, but works fine under Linux.
