Modern forensic facial reconstruction techniques are based on an understanding of skeletal variation and tissue depths. These techniques rely upon a skilled practitioner interpreting limited data. To (i) increase the amount of data available and (ii) lessen the subjective interpretation, we use medical imaging and statistical techniques. We introduce a(More)
— Interactive deformable object modeling is important for a number of application areas. Unfortunately, computational complexity quickly grows beyond the capabilities of consumer systems as model detail increases. Our first contribution is to analyze this application, and present details that might aid in optimizing existing algorithms or in developing new(More)
Physical modeling of a mass-spring system allows for realistic object motion and deformation in a virtual environment. Previous work in this type of physical modeling relies on general-purpose hardware, and cannot offer the performance necessary for real-time human-machine interaction. In this paper, we consider the co-design of software and hardware in(More)
In this paper, we discuss hardware acceleration for real-time physical modeling that would allow for realistic virtual environments. Additionally, we propose algorithms and their architectural implementation (SPARTA), which is specifically tuned for real-time use. We expect performance orders of magnitude higher than general-purpose CPUs.
