3D Object Manipulation in a Single Photograph using Stock 3D Models #3DxAnimation #3DThursday #3DPrinting

Fascinating 3D paper from the latest crop hitting Siggraph 2014 this weekend. There will be more exciting projects launching for the next week or so, but there’s a reason this one has started making the rounds early! While this project is primarily focused on manipulating 3D models in terms of 2D renderings, the implications for how this technology might impact pre-visualization and presentation of 3D models suited to 3D printing are quickly apparent.

Paper: “3D Object Manipulation in a Single Photograph using Stock 3D Models” by Natasha Kholgade, Tomas Simon, Alexei Efros, Yaser Sheikh. Via Solidsmack.

ABSTRACT:

Photo-editing software restricts the control of objects in a photograph to the 2D image plane. We present a method that enables users to perform the full range of 3D manipulations, including scaling, rotation, translation, and nonrigid deformations, to an object in a photograph. As 3D manipulations often reveal parts of the object that are hidden in the original photograph, our approach uses publicly available 3D models to guide the completion of the geometry and appearance of the revealed areas of the object. The completion process leverages the structure and symmetry in the stock 3D model to factor out the effects of illumination, and to complete the appearance of the object. We demonstrate our system by producing object manipulations that would be impossible in traditional 2D photo-editing programs, such as turning a car over, making a paper-crane flap its wings, or manipulating airplanes in a historical photograph to change its story….

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
