Representing and Rendering Distant Objects for Real-Time Visualization
(Wimmer, June 2001)
Computergraphik ist die Wissenschaft, die sich mit der Generierung glaubw¨urdiger Bilder besch¨aftigt. Eine der gr¨oßten Herausforderungen dabei ist, diese Bilder in ausreichender Geschwindigkeit zu erzeugen. Speziell bei ...
A Survey of Real-Time Hard Shadow Mapping Methods
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Because of its versatility, speed and robustness, shadow mapping has always been a popular algorithm for fast hard shadow generation since its introduction in 1978, first for offline film productions and later increasingly ...
Partial Shape Matching Using Transformation Parameter Similarity
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
In this paper, we present a method for non‐rigid, partial shape matching in vector graphics. Given a user‐specified query region in a 2D shape, similar regions are found, even if they are non‐linearly distorted. Furthermore, ...
Instant Visibility
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
We present an online occlusion culling system which computes visibility in parallel to the rendering pipeline. We show how to use point visibility algorithms to quickly calculate a tight potentially visible set (PVS) which ...
Coherent Hierarchical Culling: Hardware Occlusion Queries Made Useful
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
We present a simple but powerful algorithm for optimizing the usage of hardware occlusion queries in arbitrary complex scenes. Our method minimizes the number of issued queries and reduces the delays due to the latency of ...
Unpopping: Solving the Image-Space Blend Problem for Smooth Discrete LOD Transitions
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
This paper presents a new, simple and practical algorithm to avoid artifacts when switching between discrete levels of detail (LOD) by smoothly blending LOD representations in image space. We analyse the alternatives of ...
Temporal Coherence Methods in Real‐Time Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Nowadays, there is a strong trend towards rendering to higher‐resolution displays and at high frame rates. This development aims at delivering more detail and better accuracy, but it also comes at a significant cost. ...
High-Quality Screen-Space Ambient Occlusion using Temporal Coherence
(The Eurographics Association and Blackwell Publishing Ltd, 2010)
Ambient occlusion is a cheap but effective approximation of global illumination. Recently, screen-space ambient occlusion (SSAO) methods, which sample the frame buffer as a discretization of the scene geometry, have become ...
Separable Subsurface Scattering
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
In this paper, we propose two real‐time models for simulating subsurface scattering for a large variety of translucent materials, which need under 0.5 ms per frame to execute. This makes them a practical option for real‐time ...
Quantifying the Error of Light Transport Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
This paper proposes a new methodology for measuring the error of unbiased physically based rendering algorithms. The current state of the art includes mean squared error (MSE) based metrics and visual comparisons of ...
