EWA Splatting
In this paper, we present a framework for high quality splatting based on elliptical Gaussian kernels. To avoid aliasing artifacts, we introduce the concept of a resampling filter, combining a reconstruction kernel with a low-pass filter. Because of the similarity to Heckbert’s EWA (elliptical weighted average) filter for texture mapping, we call our technique EWA splatting. Our framework allow...
متن کاملErgonomic workplace analysis (EWA).
UNLABELLED Work Related Musculoskeletal disorders (WRMSDs) create a significant financial burden to both employer and employee that includes the cost of treatment and lost work time. There is a growing demand to implement early identification and effective prevention strategies, aimed at early intervention in employees prior to possible absenteeism due to foreseen sickness or disability. A wide...
متن کاملObject Space EWA Surface Splatting
Elliptical weighted average (EWA) surface splatting is a technique for high quality rendering of point-sampled 3D objects. EWA surface splatting renders water-tight surfaces of complex point models with high quality, anisotropic texture filtering. In this paper we introduce a new multi-pass approach to perform EWA surface splatting on modern PC graphics hardware, called object space EWA splatti...
متن کاملMotion Blur for EWA Surface Splatting
This paper presents a novel framework for elliptical weighted average (EWA) surface splatting with time-varying scenes. We extend the theoretical basis of the original framework by replacing the 2D surface reconstruction filters by 3D kernels which unify the spatial and temporal component of moving objects. Based on the newly derived mathematical framework we introduce a rendering algorithm tha...
متن کاملEwa Learning in Bilateral Call Markets
This chapter extends the EWA learning model to bilateral call market games (also known as the "sealed-bid mechanism" in two-person bargaining). In these games, a buyer and seller independently draw private values from commonly-known distributions and submit bids. If the buyer's bid is above the seller's, they trade at the midpoint of the two bids; otherwise they don't trade. We apply EWA by ass...
