MPI-IS UNVEILS THE WORLD’S FIRST HI-RES 4D BODY SCANNER TO MODEL SOFT-TISSUE MOTION

Researchers at the Max Planck Institute for Intelligent Systems unveil the world’s first high-resolution 4D body scanner and software to model detailed soft-tissue motion. According to the institute, digital characters either
lack natural soft-tissue motion or require time-consuming animation to make them believable.
To put jiggling under a microscope, the researchers needed a new type of scanner to capture 3D body shape as it is deforming.Most body scanners capture the static shape of the body. The new MPI scanner is actually made of 66 cameras and special projectors that shine a speckled pattern on a subject’s body.The system uses stereo, something like what humans do to see depth but, in this case, with 66 digital eyes.
Dr. Javier Romero, a research scientist at MPI, says the system captures high-speed “4D movies” of 3D body shape, where the 4th dimension is time. The system captures 3D body shapes with about 150,000 3D points 60 times a second.
According to Romero, the system is similar to motion capture, or “mocap,” commonly used in the animation industry except that mocap systems typically track around 50 points on the body using special markers while 4Cap tracks 15,000 points without any markers.
