“…In this case, feature reconstruction still seems preferable to bilinear filtering as it retains more structural information. Our representation cannot correctly handle curve intersections, as is the case for all approaches based on real-time perpixel feature reconstruction [Parilov and Zorin 2008]. Fortunately, as texture resolution is typically high due to the warping, such artifacts are small on screen which makes them less noticeable.…”

“…Previous work mainly varies by the type and amount of local information that is provided. Such local information can be line segments [Sen et al 2003;Sen 2004;Tumblin and Choudhury 2008;Lefebvre and Hoppe 2006], bilinear curves [Tarini and Cignoni 2005], a cubic curve [Ray et al 2005], two quadratic segments [Parilov and Zorin 2008] or a fixed number of corner features [Qin et al 2006]. Some approaches enhance raster images with sharp embedded features [Sen et al 2003;Sen 2004;Tumblin and Choudhury 2008;Lefebvre and Hoppe 2006] while others use more general vector graphics primitives that are registered to a discrete grid [Qin et al 2006;Nehab and Hoppe 2008].…”

Rendering surface details with diffusion curves

2009

Diffusion curve images (DCI) provide a powerful tool for efficient 2D image generation, storage and manipulation. A DCI consist of curves with colors defined on either side. By diffusing these colors over the image, the final result includes sharp boundaries along the curves with smoothly shaded regions between them. This paper extends the application of diffusion curves to render high quality surface details on 3D objects. The first extension is a view dependent warping technique that dynamically reallocates texture space so that object parts that appear large on screen get more texture for increased detail. The second extension is a dynamic feature embedding technique that retains crisp, anti-aliased curve details even in extreme closeups. The third extension is the application of dynamic feature embedding to displacement mapping and geometry images. Our results show high quality renderings of diffusion curve textures, displacements, and geometry images, all rendered interactively.

“…Vector textures [Kilgard 1997;Frisken et al 2000;Sen et al 2003;Sen 2004;Ramanarayanan et al 2004;Ray et al 2005;Lefebvre and Hoppe 2006;Qin et al 2006;Nehab and Hoppe 2008;Qin et al 2008;Parilov and Zorin 2008;Rougier 2013] combine the resolution independence of vector graphics with the random-access sampling of images. This enables a range of new applications, such as direct mapping of vector graphics onto 3D surfaces and creative warping effects.…”

Massively-parallel vector graphics

We present a massively parallel vector graphics rendering pipeline that is divided into two components. The preprocessing component builds a novel adaptive acceleration data structure, the shortcut tree. Tree construction is efficient and parallel at the segment level, enabling dynamic vector graphics. The tree allows efficient random access to the color of individual samples, so the graphics can be warped for special effects. The rendering component processes all samples and pixels in parallel. It was optimized for wide antialiasing filters and a large number of samples per pixel to generate sharp, noise-free images. Our sample scheduler allows pixels with overlapping antialiasing filters to share samples. It groups together samples that can be computed with the same vector operations using little memory or bandwidth. The pipeline is feature-rich, supporting multiple layers of filled paths, each defined by curved outlines (with linear, rational quadratic, and integral cubic Bézier segments), clipped against other paths, and painted with semi-transparent colors, gradients, or textures. We demonstrate renderings of complex vector graphics in state-of-the-art quality and performance. Finally, we provide full source-code for our implementation as well as the input data used in the paper.

“…Another solution consists in accessing randomly our intermediate representation at required texture coordinates. For instance, the realtime GPU based techniques of Parilov et al [2008], or Nehab et al [2008] can already handle quadratic curves, and would require little effort to be adapted to our purpose.…”

A vectorial solver for free-form vector gradients

a b c d e Figure 1: Free-form vector gradients: Our vectorial solver permits to create complex vector gradients (a). Our method is based on a triangular representation (b) that is output-insensitive and thus works with arbitrary high image resolutions. Our solver does not need to be updated for a variety of operations: (c) instancing, layering and deformation; (d) texture mapping; and even (e) environment mapping. AbstractThe creation of free-form vector drawings has been greatly improved in recent years with techniques based on (bi)-harmonic interpolation. Such methods offer the best trade-off between sparsity (keeping the number of control points small) and expressivity (achieving complex shapes and gradients). In this paper, we introduce a vectorial solver for the computation of free-form vector gradients. Based on Finite Element Methods (FEM), its key feature is to output a low-level vector representation suitable for very fast GPU accelerated rasterization and close-form evaluation. This intermediate representation is hidden from the user: it is dynamically updated using FEM during drawing when control points are edited.Since it is output-insensitive, our approach enables novel possibilities for (bi)-harmonic vector drawings such as instancing, layering, deformation, texture and environment mapping. Finally, in this paper we also generalize and extend the set of drawing possibilities. In particular, we show how to locally control vector gradients.
