Is it what you are looking for ?
Well, since I use Windows pix_share_write and read don't work, but I
guess I could do the same without those objects.
Yes, this is one approach. I was looking for another approach that
wouldn't involve taking snapshots of the scene and adding them as
textures, but I guess this is the only reasonable way of doing it (in gem)
thanks.
By the way, another question...
Suppose I have an image stream from the camera of WxH pixels, and I have
to create a (N*W)x(N*H) image composed by an NxN "grid" where each
element of the grid is either a copy of the camera image (possibly
manipulated) or an empty all-transparent image (i.e. WxH pixels with
alpha=0). So the resulting image has some transparent regions (rectangles).
Now, given that this image has to be blended with another one (which is
indeed a previous snapshot of the same input), what approach would you
recommend:
A) Use several [rectangle]s on a plane, get a snapshot of the
framebuffer and put it into a texture
B) manipulate the camera input as pix, or as texture, and compose a
bigger pix, so only at the very end, for displaying, you would use a
rectangle
?
Thanks
