Liz Upton, the director of communication at Raspberry Pi foundation covers new applications involving Raspberry Pi. Recently, she covered an advanced application of this computing software that can be applied to 3D painting. She calls the project as 3D holopainting that is actually a mixture of light-painting, hyperlapse, and stop-motion. The project has been developed by a film production and time-lapse company from Vienna, the FilmSpektakel. It was prepared by students as a graduation project for a university with the help of Raspberry Pis, natch and Raspberry Pi camera boards.
As per her the biggest challenge in this job is retrieval of footage, however, once accomplished these are capable of yielding the most spectacular results. For this particular project, the team used a ring of 24 interconnected Raspberry Pi cameras that coordinated with each other in form of 3D scanners that clicked pictures across the ring with a minimal time gap of 82 milliseconds to capture a complete movement in smallest possible bits.
The final images were then cut out and embedded over a black background and the data was then fed inside a commercial light-painting stick. For those who wish to stick to their budget and do not wish to invest heavy amounts in purchase of light painting sticks, can easily build one with the help of a few instructions. You will get the instructions for this job on either Adafruit or Raspberry Pi easily.
Under this project, a man with a low-budget ninja attire moved the stick across the cameras series where Raspberry Pi cameras were set up initially. It helped in creating impression of a hanging 3D image in air.
