Hi!
Hopefully quick, easy question (and I phrase it correctly):
Is there a way to determine the overall screen frustum of a set of channels
from *outside* the channels' render context?
I'm trying to position 2D elements wrt the view (like statistics are drawn in frameViewFinish), but need to know the overall pixel width/height before the frame is drawn (to build/position the
geometry). Seems getViewport/getPixelViewport are only valid within Channel::frameFoo functions (not, e.g., in Pipe::frameStart).
I'm probably missing something fundamental, hopefully I can be pointed to the
right spot?
Thanks!
