Content-Aware Re-targeting of Discrete Element Layouts

Example-based modeling is an active line of research within the computer graphics community. With this work we propose a re-targeting scheme for polygonal domains containing a layout composed of discrete elements. Retargeting such domains is typically achieved employing a deformation to the initial domain. The goal of our approach is it to compute a novel layout within the deformed domain re-using the discrete elements from the initial layout. We show that the deformed interior of the initial domain can guide the layout algorithm that places the discrete elements. We evaluate our algorithm by re-targeting several challenging city blocks and the results confirm that generated layouts are visually similar to the original ones.
