Abstract
A 2D polygonal shape copy-and-paste method is proposed which is based on a multiple planar shapes blending algorithm. First sub-shapes are specified and selected, which correspond to user-defined visual features on the input shapes. Then they are copied and pasted with contribution weights to generate new shapes via a modified intrinsic 2D shape blending algorithm. User can edit the generated shape intuitively by adjusting the contribution weights. The proposed method fills the gap in the object modeling methodology based on the copy-and-paste operation. Besides the static 2D copy-and-paste operation, the proposed method can also be applied to 2D metamtphosis among multiple planner shapes.
