“…The method is similar to Larboulette's work [17], but the wrinkle pattern is dynamically generated in the GPU. However, this approach uses a large part of GPU capacities that recent facial animation systems need for realistic skin rendering.…”

“…This technique requires one or several wrinkle patterns for each model. Larbourlette et al [17] used a compression detection algorithm applied to mesh triangles to trigger predefined wrinkles. The wrinkles progressively appear as the mesh is compressed.…”

“…Expressive wrinkles are then triggered from facial deformation. Triggering is based on an adaptation of clothes wrinkling [17] to MPEG-4 facial animation. Instead of computing global mesh compression to deduce wrinkles visibility, we compute the compression of the keypoints' structure to deduce wrinkles visibility.…”

Facial animation has reached a high level of photorealism. Skin is rendered with grain and translucency, wrinkles are accurate and dynamic. These recent visual improvements are not fully tested for their contribution to the perceived expressiveness of virtual characters. This paper presents a perceptual study assessing the impact of different rendering modes of expressive wrinkles on users' perception of facial expressions of basic and complex emotions. Our results suggest that realistic wrinkles increase agent's expressivity and user's preference, but not the recognition of emotion categories. This study was conducted using our real time facial animation platform that is designed for perceptive evaluations of affective interaction.

“…Oshita et al [12] proposed a geometric method to add wrinkles to the edges of a cloth mesh based on the length variation of the edges. Larboulette et al [8] described the generation of wrinkles on a cloth or skin mesh along the position and orientation specified by the designer. The curves of the wrinkles are controlled by the compression of the mesh.…”

Abstract. In this paper, we propose an easy-to-use real-time method to simulate realistic deformation of human skin. We utilize the fact that various skin deformations such as wrinkles, bulging and protruding bones can be categorized into various deformation patterns. A deformation pattern for a local skin region is represented using a dynamic height map. Users of our system specify a region of the body model in the texture space to which each deformation pattern should be applied. Then, during animation, the skin deformation of the body model is realized by changing the height patterns based on the joint angles and applying bump mapping or displacement mapping to the body model. The pattern deformation process is efficiently executed on a GPU.

“…The mesh grows and folds according to the input. Larboulette and Cani [LC04] use a curve on a surface, along which the mesh is contracted with length preservation. In a similar vein, Wang et al [WWY06] fold the neighborhood of a curve using a physical simulation and locally refining the mesh.…”

The simulation of complex layers of folds of cloth can be handled through algorithms which take the physical dynamics into account. In many cases, however, it is sufficient to generate wrinkles on a piece of garment which mostly appears spread out. This paper presents a corresponding fully GPU-based, easy-to-control, and robust method to generate and render plausible and detailed folds. This simulation is generated from an animated mesh. A relaxation step ensures that the behavior remains globally consistent. The resulting wrinkle field controls the lighting and distorts the texture in a way which closely simulates an actually deformed surface. No highly tessellated mesh is required to compute the position of the folds or to render them. Furthermore, the solution provides a 3D paint interface through which the user may bias the computation in such a way that folds already appear in the rest pose.
