Hi Tor, thanks for your quick reply
Presumably you mean an Impress slide show, and not the Impress UI (as
used to edit slide decks)?
Yes - I actually just came across the slidshow code (I was looking at
the drawing layer before) and it looks like it might be where I would
need to implement the changes - specifically
/slideshow/source/engine/OGLTrans/mac/OGLTrans_Shaders.m
which has a function "CopyFramebufferToTexture" which I'm guessing
copies the slideshow output to a texture? does anyone have any idea what
type of texture I would need to create to do this? is there a guide to
writing slide transitions or the like that might mention this?
As Impress slide shows typically are run full-screen, doesn't your
problem then (simply) become one of displaying the whole contents of
the screen (either the built-in one, or an external one if you have an
external one connected) on the dome? So if you find some way to just
display whatever is displayed on an external display onto the dome, it
will work for whatever application windows happen to be visible on the
screen at any moment. Or am I missing something? --tml
Currently we do what you mention via displaying the slideshow across 3
monitors linked into one display (via and AMD eyefinity card) and then
using hardware capture (via a blackmagic declink quad capture card) to
capture this into our warping solution (which runs on OSX). We would
like to move away from needing a second computer for this though and
creating an extension/plugin for Libre that just sends the output
texture to our warping solution.....or any other syphon apps, mad
mapper, resolume, vdmx etc.
I'm guessing this will also mean I'll need to add in some functionality
that allows me to set the size of the rendering window (to something
like 5760x1080) when its not in fullscreen mode - so any pointers tips
as to where I might find this functionality in the code would be greatly
appreciated.
Cheers - James
