Manipulation Techniques for Image-based Representations of 3D Objects in a 3D Scene

Juan Carlos Yu Yu

Traditionally, scenes or objects are represented as purely 3D graphics or through a collection of 2D images. We explore the idea of representing an entire scene as a 3D model while representing a variable object through an image-based approach.

Using an image-based approach to represent the object introduces some constrains, most notably the lack of viewpoints. We propose two manipulation techniques that address this constraint. We designed and implemented a prototype that features these manipulation tools

We evaluated the perforance of the manipulation techniques through two user studies. The results of the user studies showed us that the proposed manipulation techniques performa as well as conventional tool counterparts and also is as easy to learn.
