Computer-Assisted Paper Wrapping with Visualization

This paper proposes an approach to support a wrapping process from an object and a piece of wrapping papers by the computer animation method. The combinational information about an object and a piece of wrapping papers generates possibly multiple feasible wrapping processes. Therefore, we first argue the state of paper wrapping which represents each stage in the wrapping process, and then assume that sequences of ordered states, called state space, construct the wrapping process successively. Second, the folding operations called wrap-foldingare defined. These operations generate multiple wrapping processes on a state space which are physically feasible. Third, an algorithm of searching effective wrapping processes which satisfy demand of user is described. Finally, we give some experimental results to make the practical efficacy of proposed method clear. With the processing flow, we describe a computer assisted paper wrapping proto-type system.
