Efficient Bounding of Displaced Bézier Patches
(The Eurographics Association, 2010)
In this paper, we present a new approach to conservative bounding of displaced Bézier patches. These surfaces are expected to be a common use case for tessellation in interactive and real-time rendering. Our algorithm ...
High Quality Normal Map Compression
(The Eurographics Association, 2006)
Normal mapping is a widely used technique in real-time graphics, but so far little research has focused on compressing normal maps. Therefore, we present several simple techniques that improve the quality of ATI s 3Dc ...
Design and Novel Uses of Higher-Dimensional Rasterization
(The Eurographics Association, 2012)
This paper assumes the availability of a very fast higher-dimensional rasterizer in future graphics processors. Working in up to five dimensions, i.e., adding time and lens parameters, it is well-known that this can be ...
Non-Uniform Fractional Tessellation
(The Eurographics Association, 2008)
We present a technique that modifies the tessellator in current graphics hardware so that the result is a more uniformly distributed tessellation in screen space. For increased flexibility, vertex tessellation weights are ...
Stochastic Rasterization using Time-Continuous Triangles
(The Eurographics Association, 2007)
We present a novel algorithm for stochastic rasterization which can rasterize triangles with attributes depending on a parameter, t, varying continuously from t
Coarse Pixel Shading
(The Eurographics Association, 2014)
We present a novel architecture for flexible control of shading rates in a GPU pipeline, and demonstrate substantially reduced shading costs for various applications. We decouple shading and visibility by restricting and ...
Theory and Analysis of Higher-Order Motion Blur Rasterization
(ACM, 2013)
A common assumption in motion blur rendering is that the triangle vertices move in straight lines. In this paper, we focus on scenarios where this assumption is no longer valid, such as motion due to fast rotation and other ...
Layered Reconstruction for Defocus and Motion Blur
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Light field reconstruction algorithms can substantially decrease the noise in stochastically rendered images. Recent algorithms for defocus blur alone are both fast and accurate. However, motion blur is a considerably more ...
Per-Vertex Defocus Blur for Stochastic Rasterization
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present user-controllable and plausible defocus blur for a stochastic rasterizer. We modify circle of confusion coefficients per vertex to express more general defocus blur, and show how the method can be applied to ...
Floating-Point Buffer Compression in a Unified Codec Architecture
(The Eurographics Association, 2008)
This paper presents what we believe are the first (public) algorithms for floating-point (fp) color and fp depth buffer compression. The depth codec is also available in an integer version. The codecs are harmonized, meaning ...
