“…To avoid the limitations associated with normal maps, it is possible to bake the changes into the geometry. We implemented a recent method [DM11] for this conversion, which gives very accurate results as we illustrate in Figure 21.…”

Figure 1: We use statistics extracted from example faces to augment interactively drawn concept sketches for synthesizing realistic facial wrinkles. AbstractSynthesizing facial wrinkles has been tackled either by a long process of manual sculpting on 3D models, or using automatic methods that do not allow for user interaction or artistic expression. In this paper, we propose a method that accepts interactive sketchy drawings depicting wrinkle patterns, and synthesizes realistic looking wrinkles on faces. The method inherits the simplicity of sketching, making it possible for artists as well as novice users to generate realistic facial detail very efficiently, allowing fast preview for physical makeup, or aging simulations for fun and professional applications. All strokes are used to infer the wrinkles, retaining the expressiveness of the sketches and realism of the final result at the same time. This is achieved by designing novel multi-scale statistics tailored to the wrinkle geometry and coupled to the sketch interpretation method. The statistics capture the crosssectional profiles of wrinkles at different scales and parts of a face. The strokes are augmented with the statistics extracted from given example face models, and applied to an input face model interactively. The interface gives the user control over the shapes and scales of wrinkles via sketching while adding extra details required for realism automatically.

“…Without modifying the underlying geometry, the details of the surface can also be artificially enhanced using various methods including (1) normal mapping [82], (2) parallax mapping [83], (3) relief mapping [81], and (4) displacement mapping [82]. The additional surface details include, but are not limit to, surface bumps, cracks, light refraction, scattering effects and shadows.…”

“…For instance, Policarpo and Oliveira [81] create artificial bumps by using a relief map algorithm that relies on intensive sampling of bump texture in the fragment shader. Dmitriev and Makarov [82] show how vertex displacement maps can be computed directly from normal maps to improve the geometric details of the surfaces. Kaneko et al [83], in turn, illustrate how parallax mapping can enhance the impression of depth on the surface of a 3D object.…”

3D Internet technologies are becoming essential enablers in many application areas including games, education, collaboration, navigation and social networking. The use of 3D Internet applications with mobile devices provides location-independent access and richer use context, but also performance issues. Therefore, one of the important challenges facing 3D Internet applications is the deployment of 3D graphics on mobile devices. In this article, we present an extensive survey on optimization techniques for 3D graphics deployment on mobile devices and qualitatively analyze the applicability of each technique from the standpoints of visual quality, performance and energy consumption. The analysis focuses on optimization techniques related to data-driven 3D graphics deployment, because it supports off-line use, multiuser interaction, user-created 3D graphics and creation of arbitrary 3D graphics. The outcome of the analysis facilitates the development and deployment of 3D Internet applications on mobile devices and provides guidelines for future research. Graphical Abstract

“…When each point has been translated relative to each other in this manner, a proportionally accurate 3D surface structure is produced (Figure 1 c). In most cases however, displacement maps are only produced for aesthetic purposes; no absolute height values can be generated (Dmitriev and Makarov, 2011 ). Given that most SEM systems produce greyscale images by default, electron micrographs are a prime candidate for the production of displacement maps, and when coupled with an appropriate height calibration procedure, 3D models can be produced for a surface that contain relatively accurate height values.…”

Three-dimensional reconstruction of surface nanoarchitecture from two-dimensional datasets

The design of biomaterial surfaces relies heavily on the ability to accurately measure and visualize the three-dimensional surface nanoarchitecture of substrata. Here, we present a technique for producing three-dimensional surface models using displacement maps that are based on the data obtained from two-dimensional analyses. This technique is particularly useful when applied to scanning electron micrographs that have been calibrated using atomic force microscopy (AFM) roughness data. The evaluation of four different surface types, including thin titanium films, silicon wafers, polystyrene cell culture dishes and dragonfly wings confirmed that this technique is particularly effective for the visualization of conductive surfaces such as metallic titanium. The technique is particularly useful for visualizing surfaces that cannot be easily analyzed using AFM. The speed and ease with which electron micrographs can be recorded, combined with a relatively simple process for generating displacement maps, make this technique useful for the assessment of the surface topography of biomaterials.
