“…General texture mapping approaches, such as [BVIG91,MYV93], are powerful but require user input to generate the map. The approaches used in the Chameleon system [IC01] are more appropriate for casual, quick painting and not for highly detailed models.…”

We present a system, ArtNova, for 3D model design with a haptic interface. ArtNova offers the novel capability of interactively applying textures onto 3D surfaces directly by brush strokes, with the orientation of the texture determined by the stroke. Building upon the framework of inTouch [GEL00], it further provides an intuitive physically-based force response when deforming a model. This system also uses a user-centric viewing technique that seamlessly integrates the haptic and visual presentation, by taking into account the user's haptic manipulation in dynamically determining the new viewpoint locations. Our algorithm permits automatic placement of the user viewpoint to navigate about the object. ArtNova has been tested by several users and they were able to start modeling and painting with just a few minutes of training. Preliminary user feedback indicates promising potential for 3D texture painting and modeling.

“…However, most surfaces do not have a toroidal parameterization and cannot be unfolded onto a plane. Optimization algorithms can be used to limit texture distortion [Bennis et al 1991;Maillot et al 1993;Lévy and Mallet 1998;Lévy 2001], but cracks and singularities can hardly be avoided. Moreover, texture periodicity resulting from the mapping of a rectangular pattern is obvious and often spoils the visual quality of results.…”

“…Most local flattening methods used in previous work [Bennis et al 1991;Praun et al 2000;Wei and Levoy 2001;Turk 2001] were aimed at flattening the neighborhood of a given mesh vertex. A spiral traversal has been, for instance, used for progressively flattening the region around a vertex.…”

We present a multi-scale algorithm for mapping a texture defined by an input image onto an arbitrary surface. It avoids the generation and storage of a new, specific texture. The idea is to progressively cover the surface by texture patches of various sizes and shapes, selected from a single input image. The process starts with large patches. A mapping that minimizes the texture fitting error with already textured neighbouring patches is selected. When this error is above a threshold, the patch is split into smaller ones, and the algorithm recursively looks for good fits at a smaller scale. The process ends when the surface is entirely covered. Our results show that the method correctly handles a wide set of texture patterns, which can be used at different mapping scales. Hierarchical texture mapping only outputs texture coordinates in the original texture for each triangle of the initial mesh. Rendering is therefore easy and memory cost minimal. Moreover the initial geometry is preserved.

“…A developable surface is a surface that can be deformed to planar shape without changing length measurements in it [6]. In a similar fashion, the work presented in [3] "cuts" a given 3D parametric surface into regions which can be flattened out without warping. The minimization of distortion is achieved through a compromise between cuts and distortions.…”

Figure 1: A giraffe and its newborn generated with techniques described in the paper. AbstractThe giraffe and its patches, the leopard and its spots, the tiger and its stripes are spectacular examples of the integration of a pattern and a body shape. We present an approach that integrates a biologicallyplausible pattern generation model, which can effectively deliver a variety of patterns characteristic of mammalian coats, and a body growth and animation system that uses experimental growth data to produce individual bodies and their associated patterns automatically. We use the example of the giraffe to illustrate how our approach takes us from a canonical embryo to a full adult giraffe in a continuous way, with results that are not only realistic looking, but also objectively validated. The flexibility of the approach is demonstrated by examples of big cat patterns, including an interpolation between patterns. The approach also allows a considerable amount of user control to fine-tune the results and to animate the resulting body with the pattern.
