摘要：

The interactive use of graphic paintboxes has raised a new concept in image synthesis that is sometimes called 2 1/2D synthesis. It mainly consists of modeling scenes made of possible overlapping 2D objects, ordered with respect to depth. There exist different approaches to realize such a model. In this paper, we briefly sketch a model based on a partition of the image into elementary regions and the representation of 2D objects by a set of contours. Then we describe precisely the algorithms and data structures in relation to the fundamental operation defined in this model: the insertion of a new contour in a previously defined contour set.
