RE:Vision Effects RE:Flex creates morphs and warps in After Effects, DaVinci Resolve and Fusion. Rather than asking you to build meshes or learn a new interface, it uses the host program's own drawing and masking tools — its splines and polylines — to direct the warping and morphing.
To set up a warp, you specify "from" geometry in red and "to" geometry in yellow. Masks can be open or closed and need not be connected in any particular way. RE:Flex is the first morphing program to combine hand feature-matching with automatic image registration: its automatic alignment feature uses the tracking found in RE:Vision Effects' Twixtor to align the parts of the image you haven't matched by hand, which can improve morphs without specifying every feature manually.
You can view the warp interactively as you drag the control shapes, match vertices between corresponding geometries, and animate the amount and timing of warping per shape. Rendering uses anti-aliasing subsampling and MipMap filtering, and the product is GPU accelerated, with revamped GPU support in v5 delivering speeds up to 3x faster.
