In this work, we introduce a method for resizing a landscape specification, i.e., a vector model containing a set of objects present in a virtual environment. Our goal is to change the landscape dimensions while keeping its overall appearance. Our method is based on the insertion and removal of objects in the specification, followed by some adjustments of the scene adapting the initial model to these changes. Furthermore, this method can be easily extended to use other techniques for spreading objects in the landscape. The adjustment of the scene components consists in performing translations onto the position of the objects based on removal or insertion of paths in the grid created over the scene space, using dynamic programming. This technique is an adaptation of the Seam Carving for vector landscapes specification. This model is simpler than common images, and thus, we can achieve good results using simpler metrics.
