Good character animation requires convincing skin deformations including subtleties and details like muscle bulges. Such effects are typically created in commercial animation packages which provide very general and powerful tools. While these systems are convenient and flexible for artists, the generality often leads to characters that are slow to compute(More)
In computer graphics, many automatic methods for simplifying polygonal meshes have been developed. These techniques work very well for static meshes; however, they do not handle the case of deforming objects. Simplifying any single pose of a deforming object may destroy detail required to represent the shape in a different pose. We present an automatic(More)
In computer cinematography, the process of lighting design involves placing and configuring lights to define the visual appearance of environments and to enhance story elements. This process is labor intensive and time consuming, primarily because lighting artists receive poor feedback from existing tools: interactive previews have very poor quality, while(More)
The present study combined molecular and neuroimaging techniques to examine if free radical-mediated damage to barrier function in hypoxia would result in extracellular edema, raise intracranial pressure (ICP) and account for the neurological symptoms typical of high-altitude headache (HAH) also known as acute mountain sickness (AMS). Twenty-two subjects(More)
In this paper, we show how many interactive 3D applications’ visual styles can be changed to new, different, and interesting visual styles non-invasively. Our method lets a single stylized renderer be used with many applications. We implement this by intercepting the OpenGL graphics library and changing the drawing calls. Even though OpenGL only receives(More)
Short-Term protein-pacing (P; ~6 meals/day, >30% protein/day) and caloric restriction (CR, ~25% energy deficit) improves total (TBF), abdominal (ABF) and visceral (VAT) fat loss, energy expenditure, and biomarkers compared to heart healthy (HH) recommendations (3 meals/day, 15% protein/day) in obese adults. Less is known whether obese men and women respond(More)
Risk analysis is increasingly promoted as a tool to support science-based decisions regarding food safety. An online survey comprising 45 questions was used to gather information on the implementation of food safety risk analysis within the Latin American and Caribbean regions. Professionals working in food safety in academia, government, and private(More)
