True volumetric 3D slitscan (should it be called surface-scanning?).
“Volumetric Slit-scanning” (a term I believe I just made up 🙂 is similar to traditional 2D slit-scanning, but instead of working with 2D images + time (stored in a 3D texture cube), this technique uses a 3D camera (e.g. Kinect), spatial + temporal data stored in a 4D Space-Time Hypercube, and 3D temporal gradients (i.e. not just slit-scanning on the depth/rgb images, but surface-scanning on the animated 3D point cloud). These demos were recorded on a low-spec macbook air. Bands & blockiness due to the low spatial resolution to help performance.
