Animated paper effect
Is it possible to create an animated effect of a sheet of paper being crumpled into a ball?

Yes, through the magic of time lapse photography Smile
(of course you could try to emulate the paper crumple with "Filters > Distorts > Mosaic..." and other filters, but nothing really beats the real thing imo, plus it will be slightly less Gimp hassle)


First
You should decide whether you want a flat top-down angle of the paper being crumpled up.

or a perspective of the paper.

For the flat-top down, you can use the background layer or a white layer, for the first frame.

Next, with your camera, take one picture *click*, then crumple it some *click*
crumple it some more *click*
crumple it until its a ball *click*

If this is your first time making an animated GIF in Gimp, you'll probably want to take 5-10 frame(pictures) of the paper to keep it simple.

Next, upload your pictures from your camera's memory card to your computer into a new folder in "My documents"

(Optional, but definately can help) Name your pictures in the order you took them
Example "paper01.jpeg" "paper002.jpeg" "paper03.jpeg" etc.

Next, open Gimp, then either drag & drop the files one at a time from your animated folder to the gimp canvas (in multiple window mode, the File, edit, ect.. menus window)
Or
In, Gimp "File > Open..." & navigate to the folder you made

CREATING ANIMATION(COMPOSITE & OPTIMIZE...)
Gimp treats each layer as a frame of the animation. So if you need to erase anything on any layer, make sure you right-click on each layer & "remove alpha channel" when done.

When done with frames, click "Filters > Animation > Optimize (for GIF)..."

Let Gimp do its thing, it should open a new canvas with all the layers .

Now "File > Export..."

Type the name of the animation plus ".GIF" "example.gif"
Click the "export" button

First a "Export File" window pops up, click "()Save as Animation"
and "()convert to indexed..." if it shows
click Export again
"Save as GIF" window pop up.
- turn off "[]GIF comment"
-turn on "[]Loop Forever"
Select a delay a little more than 100 miliseconds (you'll need to experiment to find the right speed)
-turn on "[]Use delay entered above for all frames"
-off "[]Use disposal entered for all frames"

LAST, click save ^^

I am not into animation but the term to look for is 'morphing', where you progressively transform one image through a number of intermediate stages to a second image.

You can do this with the Gimp animation package GAP, but there is a learning curve.

This is my 5 minute stab at 'manual' using the iwarp filter on progressively copied layers. Then export as an animated gif.
