[PD] Extended View Toolkit

Mon May 23 05:50:20 CEST 2011

hey! thanks jose and peter!

i have updated both files in my folder...

 but im not getting any bang from ev_vid outlet (im routing with "end")

 try receiving the "/ev/vid/x/stop" too, but have no results too...

 also, i found the number from the "elapsed" in a route object in ev_vid.pd
doesnt stop or reset, it stills incrementing until i change to another group
(but if i back to these group, the numer stills counting)...

 im i doing something wrong (about the bang)?... hope you can help me again!

 thx!

sorry 4 my poor english :)

> 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: [
