Efficient Simulation of Secondary Motion in Rig-Space
(ACM SIGGRAPH / Eurographics Association, 2013)
We present an efficient method for augmenting keyframed character animations with physically-simulated secondary motion. Our method achieves a performance improvement of one to two orders of magnitude over previous work ...
Hierarchical hp-Adaptive Signed Distance Fields
(The Eurographics Association, 2016)
In this paper we propose a novel method to construct hierarchical hp-adaptive Signed Distance Fields (SDFs). We discretize the signed distance function of an input mesh using piecewise polynomials on an axis-aligned ...
Stylistic Patterns for Generating Cinematographic Sequences
(The Eurographics Association, 2015)
For film editors, the decision of how to compose and sequence camera framings is a question pertaining to a number of elements involving the semantics of shots, framings, story context, consistency of style, and artistic ...
Fisher Encoding of Adaptive Fast Persistent Feature Histograms for Partial Retrieval of 3D Pottery Objects
(The Eurographics Association, 2014)
Cultural heritage is a natural application domain for partial 3D object retrieval, since it usually involves objects that have only been partially preserved. This work introduces a method for the retrieval of 3D pottery ...
Analysis of Cache Behavior and Performance of Different BVH Memory Layouts for Tracing Incoherent Rays
(The Eurographics Association, 2013)
With CPUs moving towards many-core architectures and GPUs becoming more general purpose architectures, path tracing can now be well parallelized on commodity hardware. While parallelization is trivial in theory, properties ...
Partial 3D Object Retrieval combining Local Shape Descriptors with Global Fisher Vectors
(The Eurographics Association, 2015)
This work introduces a partial 3D object retrieval method, applicable on both meshes and point clouds, which is based on a hybrid shape matching scheme combining local shape descriptors with global Fisher vectors. The ...
Comparative Study of Layered Material Models
(The Eurographics Association, 2019)
The accurate reproduction of layered materials is an important part of physically-based rendering applications. Since no exact analytical model exists for any configuration of layer stacks, available models make approximations. ...
Temporally Coherent Adaptive Sampling for Imperfect Shadow Maps
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We propose a new adaptive algorithm for determining virtual point lights (VPL) in the scope of real-time instant radiosity methods, which use a limited number of VPLs. The proposed method is based on Metropolis-Hastings ...
Efficient Divide-And-Conquer Ray Tracing using Ray Sampling
(ACM, 2013)
Divide-and-conquer ray tracing (DACRT) methods solve intersection problems between large numbers of rays and primitives by recursively subdividing the problem size until it can be easily solved. Previous DACRT methods ...
Efficient BVH Construction via Approximate Agglomerative Clustering
(ACM, 2013)
We introduce Approximate Agglomerative Clustering (AAC), an efficient, easily parallelizable algorithm for generating high-quality bounding volume hierarchies using agglomerative clustering. The main idea of AAC is to ...
