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 ...
Multi-View Ambient Occlusion for Enhancing Visualization of Raw Scanning Data
(The Eurographics Association, 2016)
The correct understanding of the 3D shape is a crucial aspect to improve the 3D scanning process, especially in order to perform high quality and as complete as possible 3D acquisitions on the field. The paper proposes a ...
Web-based Exploration of Semantically Rich 3D Decorative Ornament
(The Eurographics Association, 2016)
The aim of this research is to document and provide easy access and exploration to 3D decorative ornament, in order to support its preservation and reuse in future products. The research focuses on the Regency style of ...
High Fidelity Facial Animation Capture and Retargeting With Contours
(ACM SIGGRAPH / Eurographics Association, 2013)
Human beings are naturally sensitive to subtle cues in facial expressions, especially in areas of the eyes and mouth. Current facial motion capture methods fail to accurately reproduce motions in those areas due to multiple ...
Fresnel Equations Considered Harmful
(The Eurographics Association, 2019)
Microfacet shading models in film and game production have long used a simple approximation to the Fresnel equations, published by Schlick in 1994. Recently a growing number of film studios have transitioned to using the ...
What is the Reddening Effect and does it really exist?
(The Eurographics Association, 2019)
The simulation of light-matter interaction is a major challenge in computer graphics. Particularly challenging is the modelling of light-matter interaction of rough surfaces, which contain several different scales of ...
Rendering Transparent Materials with a Complex Refractive Index: Semi-conductor and Conductor Thin Layers
(The Eurographics Association, 2019)
During physical simulation of light transport, we separate materials between conductors and dielectrics. The former have a complex refractive index and are treated as opaque, the latter a real one and are treated as ...
