When you think about how far and fast computer science has progressed in recent years, it's
not hard to conclude that a seven-year old handbook may fall a little short of the kind of …

Realtime ray tracing has recently established itself as a possible alternative to the current
rasterization approach for interactive 3D graphics. However, the performance of existing …

This thesis describes a ray tracing hardware architecture for dynamic scenes that makes it
possible to ray trace highly complex scenes in real time. Ray tracing of dynamic scenes …

Most CPU-based volume raycasting approaches achieve high performance by advanced
memory layouts, space subdivision, and excessive pre-computing. Such approaches …

We present a hardware-accelerated adaptive EWA (elliptical weighted average) volume
splatting algorithm. EWA splatting combines a Gaussian reconstruction kernel with a low …

This paper provides an overview of the main techniques being used for three-dimensional
(3D) visualization of medical data sets and highlights some of the clinical benefits that can …

Most volume rendering systems based on CPU volume raycasting still suffer from inefficient
CPU utilization and high memory usage. To target these issues we present a new technique …

To cope with the increasing amount of CT data, there is growing interest in direct volume-
rendering techniques (VRT) as a diagnostic tool. The aim of this phantom study was to …

Manual opacity transfer function editing for volume rendering can be a difficult and counter-
intuitive process. This paper proposes a logarithmically scaled editor, and argues that such …

This work presents a method to automatically locate facial feature points under large
variations in pose, illumination and facial expressions. First we propose a method to …
