[PD] Extended View Toolkit

Fri Jun 3 05:38:47 CEST 2011

Hello Again!

 Damn, i tought im asking too much...

 i have another question about EVT.

 here is my history... im gonna connect 3 projectores, but as i have no
enought money i will no use a matrox system (or something like these),
inseted im gonna use 3 computers, each one of them connected to a different
projector... so im gonna have 3 projectores and 3 computers...

 so, ill use a fourth computer to manage the data in the other three
computers. The manager pc will send OSC messages to each pc to turn on / off
the ev_groups. Each computer will gonna project only a part of the screen.

 my problem is, when im trying to send OSC messages to one of these
computers, the server computer doesnt recibe anything, insetead when i use
the "send" cmd locally, where all the message workg perfect...

 so, in concrete, what should be the port to send the messages via OSC from
the manager pc to the others computers?

 thanks! and thanks again!

> The Extended View Toolkit is a set of abstractions developed for the art
> installation "Extended View streamed".
> It is intended to be an easy solution to experiment and realise panoramic
> video and complex multiscreen projection
> environments to createimmersive media experiences.
>
> It features a set of abstractions that are able to combine multiple related
> image-sources
> (like video input, video playback) into aconsistent panoramic image.
> The source-material, e.g. the camera to display has to be aligned
> horicontally, since image-combination
> is based on simple, openGL basededge-blending and not algorithmic pix by
> pixel comparison.
>
> Furthermore it features abstractions to create multi-screen,
> multi-projector environments to enable
> correct representation of (not only)panoramic material. The projection
> abstractions can be combined
> to form big screens out of multiple projectors with softedge
> betweenoverlapping borders of single
> projectors and contain a vertex model that can be adjusted in 4,
> respectively 9 points, so that
> projections onchallenging geometric surfaces is possible.
>
> Additionally, all abstractions are controllable via OSC-styled
> send/receive-messages, which simplifies
> OSC-based external control.
>
> Also, since streaming video was part of the project, a gstreamer based
> streaming solution was developed
> by Peter Innerhofer to distribute panoramic/multistream video over
> network. It can be found here: [
