Morphing images with Blender

In my regular visits Blender Nation meeting new techniques developed to perform tasks with Blender for which has not been initially conceived.
In this case, Hand Francois “CoyHot” Grassard 's an interesting sequence in which, by a screenshot fast motion, shows us how to make a morphing between two pictures using only Blender.

We have seen specific tools for such tasks as FotoMorph for example, that facilitate this task with a great result. The interest of using Blender is therefore purely didactic, without ruling out possible uses of this curious technique derived.

Although the result, as he admits, is improvable, applied technique can serve as a reference for experienced variants thereof. Want to try?

Here is the screencast I launched during my researches about how to use Blender as a mophing tool. The way a morphing software works is simple to understand. It’s a mix between two warping (distortion of a single image) and a crossfade between two images.

In this video, I use two images mapped on two highly subdivided grids, with the same topology. After that, I used the wonderfull sculpt tool of Blender to “remap” (distort) the source image to match the destination image. I store the vertices offsets as vectors in a shape key. I transfer this shape to the destination image and reverse the motion vector by setting the shape weight to -1. By this way, I can deform the destination guy to match the source one … automatically.

Finally, I keyframe each shape on each grid and create a crossfade between the two images, by animating the first guy transparency.

Here is the screencast I started during my research to use Blender as a tool for morphing. How does a morphing software is simple enough to understand. This is a mixture between two warping (deformation of a single image) and a fade between two images.

In this video, I use two images mapped on two grids highly subdivided, same topolgie. I then use the wonderful tool Blender to sclupt “remapper” (deform) the source image so that it corresponds to the destination. I record offsets vertices as vectors in a shape key. I then transferred to the destination image, the reverse movements and then passing vecrteurs weight of this shape to -1. In this way, I distort the man's destination so that it is on calle source … automatically.

Finally, I keyframe each shape on each grid, and has a fade between two images, animating the opacity of the starting character.
