This paper presents several methods for shading meshes from scanned paint samples that represent dark to light transitions. Our techniques emphasize artistic control of brush stroke texture and color. We first demonstrate how the texture of the paint sample can be separated from its color gradient. We demonstrate three methods, two real-time and one off-line, for producing rendered, shaded imag...

A non-parametric method for texture synthesis is proposed. The texture synthesis process grows a new image outward from an initial seed, one pixel at a time. A Markov random field model is assumed, and the conditional distribution of a pixel given all its neighbors synthesized so far is estimated by querying the sample image and finding all similar neighborhoods. The degree of randomness is con...

In this technical report, we present a technique to synthesize featured textures easily and interactively. The main idea is to synthesize the texture by copying irregular patches from the source to the target texture, each of them containing a complete feature. The interior part of the feature is not touched while the cutting and stitching is done on the background texture between the features....

We present a system for decorating arbitrary surfaces with bidirectional texture functions (BTF). Our system generates BTFs in two steps. First, we automatically synthesize a BTF over the target surface from a given BTF sample. Then we let the user interactively paint BTF patches onto the surface, such that the painted patches seamlessly integrate with the background patterns. Our system is bas...

1 Junyu Dong and Mike Chantler are with the Texture Lab, Heriot-Watt University, Edinburgh, Scotland([email protected]) Abstract We present and compare five approaches for synthesizing and relighting real 3D surface textures. We adapted Efros’s texture quilting method and combined it with five different relighting representations, comprising: a set of three photometric images; surface gradi...

We investigate semi-stochastic tilings based on Wang or corner tiles for the real-time synthesis of example-based textures. In particular, we propose two new tiling approaches: (1) to replace stochastic tilings with pseudo-random tilings based on the Halton low-discrepancy sequence, and (2) to allow the controllable generation of tilings based on a user-provided probability distribution. Our fi...

This paper describes a method for seamless enlargement or editing of difficult colour textures containing simultaneously both regular periodic and stochastic components. Such textures cannot be successfully modelled using neither simple tiling nor using purely stochastic models. However these textures are often required for realistic appearance visualisation of many man-made environments and fo...

This paper presents a texture model that allows a two dimensional synthesis of 3D furlike texture. The model is based on the modelling of the texture autocorrelation function (ACF) and a two dimensional AutoRegressive synthesis (2D AR). We consider that the appearance of a furlike texture is deened by two characteristics: the orientation and the length of each individual element (i.e. lament). ...

Audio texture, a new audio medium, is used to synthesize long audio stream according to a given short example audio clip. In this paper, we extend this idea to audio texture restoration, or constrained audio texture synthesis for restoring those missing parts in an audio clip. It is useful in many applications such as audio restoration and audio reconstruction. It can also be used in error conc...

In building 3D site models for visualization and virtual walkthrough, most emphasis so far has been on creating the 3D shape models. Less emphasis has been on creating realistic textures, e.g. to simulate building materials or vegetation. Nevertheless, the appearance of object and landscape models will depend at least as much on their textures, as on the precision of their geometry. The paper p...
