How can you get closer to creating a model with a modifiable 3D model?

Question

Morphic model for the synthesis of 3D figures

Video above 12 years. How was the software made?

I need something simpler, but basically the same thing: a morphing model (chest), which can be changed after preliminary processing of the image.

Any links that may provide useful information are welcome.

Are there any open source projects that might have useful code that could be explored?

Answer 1

Details are given in their document:

www.mpi-inf.mpg.de/~blanz/html/data/morphmod2.pdf

In short, you need to:

• A collection of full 3D scans of samples of the class of objects that you want to characterize
• A method of performing "non-rigid registration" to align the reference template with each sample.
• Standard statistical analysis (main components) of aligned samples

Please note that their choice of the name “Morph Model” is misleading. They relate to something more specific than a set of distinguishable morphs or morphic targets.

Answer 2

What you need is called Morph Target Animation . Blender implements it, but the function is called Shape Keys.

You can see an example of morphing in NeHe Productions .

This process works by creating a basic vector of points, such as a face and a set of change vectors, that contain differences with different morph targets. A possible purpose of morphing is to smile, and it will contain offset values ​​added to the original face, leading to a smiling face.

You can make linear combinations of morph targets, and you can even create caricatures by exaggerating factors (original + 2 * smile).
