Calibrateprojector problem

vvvv beta question
1

i am missing something about mapping a cube onto a dummy scene.
the node seems to be working but the transforms don’t apply to the scene.

ps if you get a red node (having installed opencv), there is a chance you need ApplyNearAndFar (Transform). my install doesn’t locate it for some reason and i have a copy of it in the same folder as this patch

maybe you dont need this file, i get a red node without it (12.0 kB)

tested with b30, same results
solve > status ok > no scene appears

…as i said before, it used to work, back in pade-days and with first calibrateprojector version ~one year ago.
am i misusing the node?

re-attached the example with even more ref-points and a dummy_scene-picture.

here is an older test from may 2012 that used to work (b27.2, emgucv-february2012 release) and now it doesn’t.

  • missing ApplyNearAndFar (it is possible to add it)
  • solve ok / nothing
    sorry for the mess inside the patch, the clean example is one post above

this patch used to work in may2012.zip (825.7 kB)

ok, it works in b30 with emgucv-may-2012-version
it seems to be a problem with emgucv-feb-2013 version
