  • Card Wipe – Gradient Layer?

    Posted by Jon Smitherton on September 15, 2008 at 4:05 am

    Hi There,

    Have done extensive searches for my query to no avail….

    What I have is a D1 Pal fullscreen image, that I want to card flip to a multi screen box, divided into boxes of 4w x 3h of the frame.

    Would be simple if it was individual boxes, however some of the frames occupy 2 boxes and I need to not cut them up on the flip.

    Have been playing with the gradient layer to get it to flip on these irregular files to no joy.

    Anybody been able to get this to work successfully?

    Thanks,
    Jon

    i think i get what you’re after…

    you’re screen is divided up 4 across and 3 down, but you need, say, the middle two squares across to act as one card (but still flip right?).

    what you’ll need to do is cut the image into 2 pieces, the smaller gird portion and the larger grid portion. then use card wipe with the grid configurations… one that is 4×3 and the other may just need to be 1×1 if it is the exact cropped layer size… note, if card wipe can’t do a 1×1 grid (i’ve never tried), you could flip the layer manually (make it 3d, rotate on x or z axis).

    Kevin is correct that it might be easier to simply do this on individual 3d layers rotating/flipping. however, creating a gradient layer for controlling the flips is farily easy, too. you will use a 4×3 grid of boxes. Replace the boxes you want to move first with near white (say, r240g240b240) and the boxes you want to move last with black. Your group of boxes should be the same shade of gray and any boxes that are the same shade of gray will move together.

    you can get a feel for the gradient control capabilities by using any checkerboard pattern that uses at least three or four shades of monochrome. It’s fun but it’s not intuitive!

    This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

    [david bogie] “boxes that are the same shade of gray will move together.”

    bogie is right, but i think it would be more precise to say they will move ‘together’ at the same time, rather than ‘together’ as one piece….

    i believe if you had 2 cards that were side by side and the rotation for the cards was along the vertical axis, the 2 cards would flip as 2 separate cards, but at the same time… however, if the flip axis was horizontal, then they would seemingly flip as one card…

    the opposite would be true if the cards to be flipped as one were stacked on top of each other…

    so it come may come down to how you want the flip to happen…
