“…Even though the methods mentioned above could get homogeneous and seamless texture, they seem not put attention on the real world texture of the model. Walter et al [12] integrate a biologically plausible pattern generation model, which can effectively deliver a variety of patterns characteristic of mammalian coats. Zhang et al [13] present an approach for decorating surfaces with progressively variant textures.…”

This paper proposes a novel method to complete the missing appearance of mesh surfaces through structure propagation and texture matching. In advance, the appearance on surfaces is divided into structure and texture components. First, the missing structures are predicted through structure propagation. The structure propagation is guided by surfaces geometric features by using 3D tensor voting and crest line detection. Then, with the guidance of predicted structures, the optimal local sample patches are matched to inpaint the missing texture. Finally, the completed result is obtained by mapping the optimal patches to the missing texture regions on surface. We acquire convincing completion results as shown in the experiments and comparisons.

“…For completeness, we briefly review it here. For more details we refer the reader to the original papers [30], [31]. The model assumes that the coat patterns for some mammals represent a spatial arrangement of epithelial cells -a Mosaic -where all pattern elements are derived from a single mother cell, and are therefore clones.…”

Fig. 1. Real (left) and virtual (right) Codiaeum Variegatum generated with our approach.Abstract-There has been a lot of progress in modeling and rendering elements of our Natural World for computer graphics tasks. In the Plant Kingdom, techniques for modeling the visual patterns presented in many natural objects (such as stripes on a watermelon) have advanced far less than methods for modeling the shape and reflectance properties of individual or large collections of elements (such as leaves and trees). In this paper we explore a procedural model for synthesis of many familiar visual patterns from the Plant Kingdom. Our results show that in this context a procedural model has advantages over other texturing techniques such as texture mapping and procedural noise, since these patterns are usually needed in great quantity, and at least for some plants, with many geometric variation, assigning consistent texture coordinates is a challenge. We show results for fruits, mushrooms, and small decorative plants.

“…We used k f = 0.04 in our results. Measuring these distances on a mesh is not trivial, and an approximation presented in [23] is used. Basically, all computations are made on the supporting plane of the point being considered.…”

“…At this stage of the algorithm, for each polygon on the mesh, we have a collection of evenly spaced points that represent the tiles. As in the relaxation step explained above, we use an approximation for the computation of the Voronoi diagram presented in [23]. We compute the Voronoi diagram of this collection of points on the plane of the supporting polygon, and map all neighboring faces to this same plane.…”

Mosaic sculptures are a form of art where the sculpture is made from a collection of individual elements called tiles which are distributed over the surface of a given 3D shape. To add expressiveness, artists distribute the tiles following a high-level design over the shape, in order to emphasize some features. In the method known by mosaicists as Opus Palladium, or simply "crazy paving", tiles with irregular shapes are used, improving the expressivity of the final result. In this work, we present a method to simulate this kind of 3D mosaic by representing tiles as Voronoi polygons computed from a distribution of points on the surface of the 3D object. Previous work on this topic have used only square-shaped tiles. Special mosaic-like effects are obtained with the help from texture maps, which control the high-level design of the tiles.
