3D Printer
- This type of the 3D printers using stereo-lithography use uv on liquid resin and hardens the outline of an object. XYZ Printing sells stereo-lithography type at around $1500. The cartridge is costly, and the whole thing must be replaced. Carpet would be a problem.Kinect (3D sensor)
- Kinect does offer SDK that works with regular PC's, yet they would need more developers. Reportedly, the detection precision may not be good enough depending on the application. Your motion would be recorded, yet another concern for privacy.
Drones
- The drones of various types are sold on the market. The stability, the ease of use, and price range vary. They can carry a camera.
Virtual Reality (Oculus VR)
- Virtual reality offers more realistic 3d images. If more films adapted this technology, that opens a big market. Creating such video clips would be a challenge.
