Extended View ToolkitCreated on: 2012-10
by: CO-ME-DI-A
Extended View Toolkit is a set of abstractions for combining multiple video or image sources into a panoramic image and for projection setups with mutliple 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/).
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.
