Interactive modeling of complex geometric details based on empirical mode decomposition for multi-scale 3D shapes

Abstract

In this paper we develop an interactive modeling system for complex geometric details transformation based on empirical mode decomposition (EMD) on multi-scale 3D shapes. Given two models, we aim to transfer geometric details from one model to another one in an interactive manner. Taking full advantages of the multi-scale representation computed via EMD, different-scale geometric details can be transferred individually or in a concerted way, which makes our algorithm much more flexible than cut-and-paste and cloning based methods in transferring geometry details. In this process, the target surface with new transferred details could be generated by a mesh reconstruction method widely used in Laplacian surface editing. With the original positions of target surface serving as the soft constraints, the overall shape of the target model will be fully preserved. Our method can also support real-time continuous details transfer. Compared with state-of-the-art algorithms, our method provides an easier-to-use modeling tool and produces varied modeling results. We demonstrate the effectiveness of our modeling tool with various applications, such as detail transfer and enrichment, model reuse and recreation, and detail recovery for shape completion.

Bas-relief modelling from enriched detail and geometry with deep normal transfer

“…Given target shapes, viewpoints and space restrictions, Zhang et al [18] find a global optimal surface that delivers the desired appearance when observed from the designated viewpoints, which could guarantee exact depth bounds of per-vertex. Zhang et al [19] treat an input object as a continuous relief depth map and use mesh intersection to paste the relief on the target object based on empirical mode decomposition in multi-scale levels [20].…”

Visual saliency‐based bas‐relief generation with symmetry composition rule

“…Their method preserved target details into the overall shape of a target model, whereas the source model details can also be interfered by the target model. Zhang et al reconstructed an input object as a continuous relief depth map and used mesh intersection to paste the relief on the goal object. In contrast to their method, we do not require the model to be converted into depth maps, and the processes are more concise.…”
