Consistent Surface Model for SPH-based Fluid Transport
(ACM SIGGRAPH / Eurographics Association, 2013)
Surface effects play an essential role in fluid simulations. A vast number of dynamics including wetting of surfaces, cleansing, and foam dynamics are based on surface-surface and surface-bulk interactions, which in turn ...
LandSketch: A First Person Point-of-View Example-Based Terrain Modeling Approach
(ACM, 2013)
We present an intuitive interface for easy modeling of terrains, compatible with example-based synthesis approach. The interface consists on a picture's canvas-like screen, where the user sketches silhouettes of mountains, ...
Accurate Surface Embedding for Higher Order Finite Elements
(ACM SIGGRAPH / Eurographics Association, 2013)
In this paper we present a novel approach to efficiently simulate the deformation of highly detailed meshes using higher order finite elements (FE). An efficient algorithm based on non-linear optimization is proposed in ...
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 ...
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 ...
Rod Constraints for Simplified Ragdolls
(ACM SIGGRAPH / Eurographics Association, 2013)
Physics-based animation has become a standard feature in modern games. Typically, the bones in a character's animation rig are each associated with a simulated rigid body, leading to a jointed assembly commonly called a ...
Imperfect Voxelized Shadow Volumes
(ACM, 2013)
Voxelized shadow volumes [Wyman 2011] provide a discretized view-dependent representation of shadow volumes, but are limited to point or directional lights. We extend them to allow dynamic volumetric visibility from area ...
Artistic Simulation of Curly Hair
(ACM SIGGRAPH / Eurographics Association, 2013)
Artistic simulation of hair presents many challenges - ranging from incorporating artistic control to dealing with extreme motions of characters. Additionally, in a production environment, the simulation needs to be fast ...
Control of Rotational Dynamics for Ground Behaviors
(ACM SIGGRAPH / Eurographics Association, 2013)
This paper proposes a physics-based framework to generate rolling behaviors with significant rotational components. The proposed technique is a general approach for guiding coordinated action that can be layered over ...
