“…Generally, people have some prior knowledge of the ridge-valley feature to be enhanced, which can be described by the position and normal. To integrate prior knowledge into feature enhancement, this paper proposes the objective equation, as shown in equation (3), which is composed of the position constraint term p E and the normal constraint term n E . Among them, p E is used to constrain the difference between the enhanced feature position and the user expected position; n E is used to make the enhanced surface normal conform to user priori; and  is used to balance the importance of both.…”

“…The use of curve networks as a global control structure for guiding surface deformation is an appealing idea [28,18,45,19]. However, curve networks are generally structured in order to define patch boundaries.…”

Aesthetic surface mesh modification, guided by a deforming feature line, is still a challenging task. Whereas most existing surface deformation methods work well when the new surface is stretched or isometrically deformed, in case of areas subjected to compression, unwanted bulging may appear. This configuration typically appears when a designer slides a feature line along the input surface. In this paper, we present a new approach for feature line modification solving the surface bulging problem. We consider physically-based deformation methods applied to surface meshes and characterize configurations that produce compression loading from a mechanical standpoint. Then, the deformation area is decomposed into two sub-domains with a boundary modification of the one subjected to compression loading. Thus, during a subsequent deformation, this sub-domain no longer undergoes a compression loading but rather a traction loading, which ultimately prevents bulging. This transformation looks like a retraction of this surface area and a corresponding processing pipeline is set up. Our feature line modification method is intuitive to use and runs interactively, making it attractive to be used during design reviews in immersive environments. Industrial examples and comparisons with state-of-theart physically-based deformation methods validate the proposed approach.
