The Split Grid - A Hierarchical 1D-Grid-based Acceleration Data Structure for Ray Tracing
(The Eurographics Association, 2014)
We present a new acceleration structure for ray tracing called the Split Grid. Combining concepts of hierarchical grids, kd-trees and Bounding Volume Hierarchies (BVHs), our approach is based on the idea of nesting 1D-grids. ...
Light Chisel: 6DOF Pen Tracking
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a novel interaction device tracked in 6 degrees of freedom by two commodity cameras. The inexpensive Light Chisel is statically illuminated with two LEDs, and uses no additional sensor (e.g. inertial or magnetic) ...
Arm Swinging vs Treadmill: A Comparison Between Two Techniques for Locomotion in Virtual Reality
(The Eurographics Association, 2018)
When it comes to locomotion in Virtual Reality (VR), a wide range of different techniques has been proposed in the scientific literature or as commercial products. However, the best choice for a specific application is ...
Quantifying 3D Shape Similarity Using Maps: Recent Trends, Applications and Perspectives
(The Eurographics Association, 2014)
Shape similarity is an acute issue in Computer Vision and Computer Graphics that involves many aspects of human perception of the real world, including judged and perceived similarity concepts, deterministic and probabilistic ...
