A simple and efficient method is presented which allows improved rendering of glyphs composed of curved and linear elements. A distance field is generated from a high resolution image, and then stored into a channel of a lower-resolution texture. In the simplest case, this texture can then be rendered simply by using the alpha-testing and alpha-thresholding feature of modern GPUs, without a custom shader. This allows the technique to be used on even the lowest-end 3D graphics hardware. With the…

Texture-based Rendering of Vector-based Shapes

This work presents an approach to store vector-based shapes into discrete raster-based textures, optimized for parallel rendering, done by encoding the shape as piece-wise cubic Bezier curves, structured in a quad-tree.

GPU-Centered Font Rendering Directly from Glyph Outlines

This paper describes a method for rendering antialiased text directly from glyph outline data on the GPU without the use of any precomputed texture images or distance fields, and promotes high GPU utilization with an implementation that naturally avoids divergent branching.

Improved Corners with Multi‐Channel Signed Distance Fields

An extension to the state‐of‐the‐art text rendering technique based on sampling a 2D signed distance field from a texture significantly improves the visual quality of sharp corners, which is the most problematic feature to reproduce for the original technique.

Vector Textures Implementation in Photorealistic Rendering System on GPU

This work presents the experience of implementing support for vector textures in GPU based photorealistic rendering system using two different approaches – one based on signed distance fields and another based on rasterization.

Precise vector textures for real-time 3D rendering

A simple algorithm is presented that can efficiently and accurately compute the minimum distance to a parametric curve when the sample point is within its radius of curvature and the curve can be segmented into monotonic regions.

Higher Quality 2 D Text Rendering

Even though text is pervasive in most 3D applications, there is surprisingly no native support for text rendering in OpenGL. To cope with this absence, Mark Kilgard introduced the use of texture

No more texels; no more facets: Emerging trends in GPU procedural shading

The state of the art in the field of procedural texturing is presented - most of this is yet to be implemented in commercial projects like games, VR and visualization applications.

Vector Graphics for Real-time 3D Rendering

Algorithms are presented that enable the use of vector graphics representations of images in texture maps for 3D real time rendering and an iterative algorithm is discussed that can compute the distance to any parametrically differentiable curve (including polynomial splines of any order) robustly.

Interactive GPU-based Image Deformation for Mobile Devices

This work proposes the concept of an intermediate deformation buffer that stores deformation information at a resolution independent of the mesh resolution, and presents a fully GPU-based implementation of this concept, taking advantage of modern OpenGL ES features, such as compute shaders.

This paper addresses the real-time magnification problem by extending the silhouette map algorithm to general texturing and discusses the creation of these silmap textures as well as a simple filtering scheme that allows for viewing at all levels of magnification.

Resolution independent curve rendering using programmable graphics hardware
