“…To stitch the details onto the base mesh, our hybrid approach utilizes the Discrete Exponential Map (DEM) algorithm first proposed by Schmidt et al [22] and then generalized by Takayama et al [10]. In [23] the authors have proposed a novel approach for mesh cloning approach based on pyramid spherical coordinates driven by boundary loop, which extends an existing algorithm for computing offset membrane on mesh. The source and target meshes are mapped onto a 2D parametric domain using geodesic polar maps.…”

Organic modeling of 3D characters is a challenging task when it comes to correctly modeling the anatomy of the human body. Most sketch based modeling tools available today for modeling organic models (humans, animals, creatures etc) are focused towards modeling base mesh models only and provide little or no support to add details to the base mesh. We propose a hybrid approach which combines geometrical primitives such as generalized cylinders and cube with Shape-from-Shading (SFS) algorithms to create plausible human character models from sketches. The results show that an artist can quickly create detailed character models from sketches by using this hybrid approach. & 2015 Society of CAD/CAM Engineers. Production and hosting by Elsevier.

“…However, due to the unreliable and unstable cage being generated, self-intersection may occur when dealing with complex details. Following the framework of GeoBrush, Qian et al [8] used pyramid spherical coordinates for deforming the ROIs instead of Green coordinates to keep the results both seamless and natural. The proposed method requires the target ROI boundary loop should be well registered with the source ROI boundary loop.…”

“…However, during the process of cage generation, selfintersection may occur when dealing with surfaces containing complex geometric details. Following the framework of Geo-Brush [7], Qian et al [8] deformed the ROIs via pyramid spherical coordinates instead of green coordinates, which could avoid cage generation. Overall, the ROIs of target model in cut-andpaste and cloning operations are completely replaced by the source details, it is not flexible enough and hard for re-editing them simultaneously.…”

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.

“…Ridge -valley features are important elements in point clouds that can intuitively sketch the basic shape of objects. These features have important applications in fields including surface reconstruction [1], surface editing [2][3], visual perception [4] and multi-perspective data registering [5]. In general, point clouds are obtained by digitizing real objects with vision measuring equipment.…”
