RE:Flex Tutorial File: SimpleWarp

The first thing to notice when you open this project is that there are two compositions: 1) Bulging Eyes and 2) Smile. These compositions illustrate the trivial use of RE:Flex Warp.

1) BulgingEyesNoBoundary

When you open the composition, you'll notice that there are 2 rotoshapes for the BulgingEyesNoBoundary node. The main counterpart for the rotoshapes are the "from" geometries and the edge counterpart for the rotoshapes are the "to" geometries. There is no boundary set for the warp.

To do: set Shake's interactive scale to 1/2. Select the BulgingEyesNoBoundaryNode and, while in Edge mode for the rotoshape editing, drag around various rotospline points. Note how the image warps interactively.

To do: Select "None" for DrawFromGeom and DrawToGeom to turn off the magenta and blue drawing.

BulgingEyesNoBoundary Node.

1b) BulgingEyesWithBoundary

In this node we added a rotoshape to bound the warping region of the eyes. Note how the whole head no longer distorts... only the area within the boundary is allowed to warp.

When we set RE:Flex Warp to use the boundary, we get the following result:

BulgingEyesWithBoundary, yellow mask is boundary.

2) Smile

When you open the composition, you'll notice that there are 3masks. One is the "from" geometry for the mouth, and one is the "to" geometry.. The last geometry is a boundary which limits the warp.

Smile node, frame 0 ("from" and "to" shapes line up, to produce no warping).
