We present a novel method for texture synthesis on surfaces from examples. We consider a very general type of textures, including color, transparency and displacements. Our method synthesizes the texture directly on the surface, rather than synthesizing a texture image and then mapping it to the surface. The synthesized textures have the same qualitative visual appearance as the example texture...

Texture mapping has traditionally added visual realism to computer graphics images. Modern graphic boards reserve more space for image textures that are mapped in real time on 3D meshes. Outside the graphic accelerators texture images are stored in popular compressed formats that are not designed to meet real-time texture decompression requirements. In the paper we forward an alternative techni...

A technique is presented for line art rendering of scenes composed of freeform surfaces. The line art that is created for parametric surfaces is practically intrinsic and is globally invariant to changes in the surface parameterization. This method is equally applicable for line art rendering of implicit forms, creating a unified line art rendering method for both parametric and implicit forms....

This paper describes further developments of the SUM tool, initially developed for the sonification of images, towards the composition and execution of graphic scores. Closer integration of the SUM user library within the computer-aided composition environment of PWGL has allowed the composition and realization of more complex graphic scores. After first explaining the existing structure and so...

The paper proposes an ancient landscape design as an example of graphic design for an age and place where no written documents existed. It is created by a network of earthworks, which constitute the remains of an extensive ancient agricultural system. It can be seen by means of the Google satellite imagery on the Peruvian region near the Titicaca Lake, as a texture superimposed to the backgroun...

Melanocytic nevi are recognized as precursors of melanoma. Aiding in early recognition of melanoma, we estimated color texture parameters, fractal dimension and lacunarity of melanoma and other melanocytic nevi. Digital images of the lesions were processed. Graphic three-dimensional pseudoelevation images of the lesions and surrounding skin were produced to identify irregularities in color text...

Extruded shapes and patterns are widely used by graphic designers to increase the visual richness and realism of 3D models and virtual environments in general. However, the traditional approach that uses polygonal mesh is inappropriate for real-time rendering, in which, just a limited number of graphic primitives can be processed. Hence the interest of using per-pixel approaches. In this paper,...

Most of handwritten mathematical documents contain graphics in addition to mathematical text. Thus, these documents must be segmented into homogenous areas to facilitate their digitization. Text and graphic segmentation from these documents aims at segmenting the document into two blocks: the first contains the texts and the second includes the graphical objects. In this paper, we focus our int...

We introduce a new texture representation that combines standard bi-linearly interpolated samples, for smoothly varying regions, with customizable discontinuities for sharp boundaries between these regions. It consists in a standard signal texture, plus a second texture we call pinchmap, which encodes discontinuities along generally curved lines; this structure is stored in texture memory as a ...
