Automatic 3D object placement for 3D scene generation

This paper describes an automatic 3D object placement system for 3D scene generation. The layout work for a 3D scene takes a lot of time because 3D objects have six degrees of freedom (DOF) and are usually controlled by a 2D input device. To deal with this problem., the authors propose a framework to automatically generate 3D scenes. The framework mainly consists of placement constraints represented as a semantic database of 3D objects. With this framework, the prototype system can automatically lay out most 3D objects without user manipulations. This paper mainly describes this framework, and delineates its usefulness by showing experimental results.
