Deferred Attribute Interpolation for Memory-Efficient Deferred Shading
(ACM Siggraph, 2015)
In this work we present a novel approach to deferred shading suitable for high resolution displays and high visibility sampling rates. We reduce the memory costs of deferred shading by substituting the geometry buffer with ...
Adaptively Layered Statistical Volumetric Obscurance
(ACM Siggraph, 2015)
We accelerate volumetric obscurance, a variant of ambient occlusion, and solve undersampling artifacts, such as banding, noise or blurring, that screen-space techniques traditionally suffer from. We make use of an efficient ...
Perception of Highlight Disparity at a Distance in Consumer Head-Mounted Displays
(ACM Siggraph, 2015)
Stereo rendering for 3D displays and for virtual reality headsets provide several visual cues, including convergence angle and highlight disparity. The human visual system interprets these cues to estimate surface properties ...
An Evaluation of the Effects of Hyper-Natural Components of Interaction Fidelity on Locomotion Performance in Virtual Reality
(The Eurographics Association, 2015)
Virtual reality (VR) locomotion techniques that approximate real-world walking often have lower performance than fully natural real walking due to moderate interaction fidelity. Other techniques with moderate fidelity, ...
Hybrid Eye Tracking: Combining Iris Contour and Corneal Imaging
(The Eurographics Association, 2015)
Passive eye-pose estimation methods that recover the eye-pose from natural images generally suffer from low accuracy, the result of a static eye model, and the recovery of the eye model from the estimated iris contour. ...
Ring-shaped Haptic Device with Vibrotactile Feedback Patterns to Support Natural Spatial Interaction
(The Eurographics Association, 2015)
Haptic feedback devices can be used to improve usability, performance and cognition in immersive virtual environments (IVEs) and have the potential to significantly improve the user's virtual reality (VR) experience during ...
An Incremental Rendering VM
(ACM Siggraph, 2015)
We introduce an incremental rendering layer on top of standard graphics APIs such as OpenGL or DirectX in the form a virtual machine (VM), which efficiently maintains an optimized, compiled representation of arbitrary ...
A new sharp-crease bending element for folding and wrinkling surfaces and volumes
(ACM Siggraph, 2015)
We present a novel sharp-crease bending element for the folding and wrinkling of surfaces and volumes. Based on a control curve specified by an artist or derived from internal stresses of a simulation, we create a piecewise ...
Morton Integrals for High Speed Geometry Simplification
(ACM Siggraph, 2015)
Real time geometry processing has progressively reached a performance level that makes a number of signal-inspired primitives practical for on-line applications scenarios. This often comes through the joint design of ...
