Recent Advances in Computational Videography for Entertainment Production
Wednesday, 13 August 3:15 PM - 4:30 PM | Vancouver Convention Centre, East Building, Room 3

The session focuses on research developing flexible technologies to combine real and computer generated imagery. It will feature results from three EU funded research projects: SCENE, Dreamspace and IMPART.

User-centric Video Processing
Wednesday, 13 August, in the morning

Advanced Lighting
Wednesday, 13 August, in the afternoon

At the Intel booth we will demonstrate the "Vertex Connection and Merging" algorithm for lighting simulation created by Iliyan Georgiev from Saarland University et al. For the first time this algorithm combines (bidirectional) Monte-Carlo path tracing with Photon Mapping. Together the integrated algorithms can now simulate all the important lighting effects - including caustics - in a highly efficient way.

Already a few month after its publication this algorithms had been integrated into several commercial rendering systems. In particular, it is now also a core feature of Pixar's new version of Renderman tools.




Structure-Aware Shape Processing
Monday, 11 August 2:00 PM - 5:15 PM | Vancouver Convention Centre, West Building, Rooms 211-214

Shape structure is about the arrangement and relations between shape parts, which enables analysis and processing at a high level. A whole new area of structure-aware shape-processing algorithms has emerged to illuminate structure in shapes and potentially change how we capture, manipulate, and interact with shapes.

Recent Advances in Light-Transport Simulation: Some Theory and a Lot of Practice
Tuesday, 12 August 2:00 PM - 5:15 PM | Vancouver Convention Centre, West Building, Rooms 109-110

This overview of recent advances in robust light-transport simulation methods exposes the path-integral formulation of light transport as a unifying framework for many practical global illumination algorithms. Then it focusses on the issues associated with application of these methods in the industry.

Technical Papers

Points & Reconstruction
Monday, 11 August 3:45 PM - 5:15 PM | Vancouver Convention Centre, East Building, Ballroom A

Floating Scale Surface Reconstruction

Introducing a novel, virtually parameter-free method for surface reconstruction from oriented, scale-enabled point samples. The approach constructs an implicit function as the sum of compactly supported basis functions. The final surface is extracted as the zero-level set of the implicit function.

Learning a Manifold of Fonts

A method for learning a generative manifold for fonts that allows for novel applications in terms of interpolation between fonts, easier font editing, and generation of new fonts and missing characters.

Subspace & Spacetime
Wednesday, 13 August 10:45 AM - 12:15 PM | Vancouver Convention Centre, East Building, Ballroom B-C

Animating Deformable Objects using Sparse Spacetime Constraints

A scheme for animating soft-body characters and deformable objects from sparse input. Interesting motion with rich secondary motion can be created from partial keyframes for positions and velocities. The scheme is based on a framework for trajectory optimization with sparse spacetime constraints.

Wednesday, 13 August 10:45 AM - 12:15 PM | Vancouver Convention Centre, East Building, Exhibit Hall A

On-line Learning of Parametric Mixture Models for Light Transport Simulation

Using parametric-mixture models for importance sampling in light-transport simulation. The core of the approach is online model learning from a continuous stream of particles.

Unifying Points, Beams, and Paths in Volumetric Light Transport Simulation

This paper proposes a robust rendering algorithm that combines the strengths of point- and beam-based volumetric radiance estimators with the versatility of bidirectional path tracing. The algorithm excels at rendering scenes with different kinds of media, where previous specialized techniques require a significantly longer time to converge.

Relating Shapes Via Geometric Symmetries and Regularities

This paper examines the usage of symmetry relations for matching shapes of strongly varying geometry and shows that symmetry-based cues can help in finding correspondences in pairs of shapes that are very hard to relate with previous, geometry-based methods.

Modeling and Optimizing Eye Vergence Response to Stereoscopic Cuts

This paper describes a series of eye-tracking experiments to derive and evaluate a model describing adaptation of vergence to changes of disparity on a stereoscopic display. Estimated average observer parameters of the model were derived from the gathered data. This enables a range of strategies for minimizing the adaptation times.
