Retargeting 3D objects and scenes

Abstract

We introduce an interactive method suitable for retargeting both 3D objects and scenes under a general framework. Initially, an input object or scene is decomposed into a collection of constituent components embraced by corresponding control bounding volumes which capture the intra-structures of the object or the semantic groupings of the objects in the scene. The overall retargeting is accomplished through a constrained optimization by manipulating the control bounding volumes. Without inferring the intricate dependencies between the components, we define a minimal set of constraints that maintain the spatial arrangement and connectivity between the components to regularize valid retargeting results. The default retargeting behavior can then be easily altered by additional semantic constraints imposed by users.
