Material appearance constancy across different rendering platforms
Abstract: In most 3D applications, the appearance of a homogeneous, opaque surface is represented by the Bidirectional Reflectance Distribution Function (BRDF). A great number of BRDF models have been developed for material appearance representation, due to the lack of a general BRDF model able to realistically reproduce the full range of existing materials. In digital 3D content creation, it is common to use many different commercial and in-house 3D rendering tools.
Unfortunately, little has been done to facilitate consistent exchange of material models that preserve appearance across different renderers, and material appearance of rendered objects depends heavily on the underlying BRDF implementation. This is particularly complex, since it leads to visual deviations even between identically named reflectance models.
Consequently, there is no way to guarantee visual consistency between different applications used in a typical work-flow pipeline. This talk will discuss a genetic algorithm-based approach to derive a perceptually accurate mapping between the parameter spaces of parametric BRDFs, exploiting features to which the human visual system is very sensitive, such as color and gradient differences.

Advances in Parallel Real-Time Cyber-Physical Systems
Abstract: New advances in parallel real-time scheduling theory and concurrency platforms are enabling a new generation of cyber-physical systems, which can support a challenging combination of (1) significant computational demands, (2) stringent timing constraints, and (3) dynamic and substantial changes in tasks' demand for computational resources at run-time.
This talk will describe a series of recent advances in parallel real-time systems research, including both theoretical and practical results, and how each of them impacts the specific domain of real-time hybrid simulation: a cyber-physical approach to high-fidelity integration of simulation, sensing, actuation, and control that is increasingly relevant for earthquake engineering, autonomous vehicles and other related applications.
Bio: Chris Gill is a Professor of Computer Science and Engineering at Washington University in St Louis, Missouri, USA. His research spans real-time, embedded, and cyber-physical systems, with more than 90 peer-reviewed papers and articles in press over the past two decades. He was Washington University Principal Investigator for the CyberMech project (collaborative with Purdue University) that pioneered parallel real-time computing in real-time hybrid simulation.
Dr Gill has served as a Technical Program Chair and as a General Chair for the ICCPS, RTAS and RTSS conferences, as Treasurer of the IEEE Technical Committee on Real-Time Systems (TCRTS), and as Vice Chair of ACM SIGBED. Named a member of the IEEE Computer Society’s Golden Core in 2013, Dr Gill is a senior member of the IEEE and of the ACM.
