Morphing Between Two Images
Although the Warp 2D tool warps a single image, you can morph between
two images using the following workflow:
To warp between two images:
1 Add a Warp 2D tool node to image A.
2 Place all your source shapes onto image A.
3 Change the viewer to be viewing image B using a context point, and align
all the destination shapes on the corresponding features of image B.
4 Animate the Warp from 0 to 1 interpolation, which warps image A toward
B.
5 Copy the Warp tool, select the Invert-Warp button and connect Image
B as its input.This will warp Image B backwards towards A.
6 Add a Blend tool node between the two warp outputs and animate it
from 0 to 1.
2D Transforms
With the exception of Lens Distort and the Warp 2D tool, all warping tools
let you translate, rotate, scale and change the center of the input, effect and
output image. Transformations on the input image will be done before applying
the effect and its transforms. The transformations on the output image will
be done after applying the effect and its transforms—see
2D Transform Tool
on page 432.
