Generalized Light Portals
(ACM, 2020)
Light portals are useful for accelerating the convergence of Monte Carlo path tracing when rendering interiors. However, they are generally limited to flat polygonal shapes. In this paper, we introduce a new concept that ...
Efficient Adaptive Deferred Shading with Hardware Scatter Tiles
(ACM, 2020)
Adaptive shading is an effective mechanism for reducing the number of shaded pixels to a subset of the image resolution with minimal impact on final rendering quality. We present a new scheduling method based on on-chip ...
Quadratic Approximation of Cubic Curves
(ACM, 2020)
We present a simple degree reduction technique for piecewise cubic polynomial splines, converting them into piecewise quadratic splines that maintain the parameterization and C1 continuity. Our method forms identical tangent ...
Sub-triangle opacity masks for faster ray tracing of transparent objects
(ACM, 2020)
We propose an easy and simple-to-integrate approach to accelerate ray tracing of alpha-tested transparent geometry with a focus on Microsoft® DirectX® or Vulkan® ray tracing extensions. Pre-computed bit masks are used to ...
Sunlight Simulation of the Church of Saint Nectaire in Virtual Reality: a Digital Time Machine
(The Eurographics Association, 2020)
The roman church of Saint Nectaire, like many churches in Auvergne, France, is richly decorated with carved capitals. Most of them represent figures or symbols of Christianity and are periodically illuminated by the sunlight ...
Engaging audiences with Cultural Heritage through Augmented Reality (AR) Enhanced Pop-Up Books
(The Eurographics Association, 2020)
One of the core activities of memory institutions is to provide access to heritage material from their collections so that it can be used in formal and informal educational activities. Although this type of access is ...
Segmentation-Based Near-Lossless Compression of Multi-View Cultural Heritage Image Data
(The Eurographics Association, 2020)
Cultural heritage preservation using photometric approaches received increasing significance in the past years. Capturing of these datasets is usually done with high-end cameras at maximum image resolution enabling high ...
The V-Horus Project
(The Eurographics Association, 2020)
The V-Horus Project aims to reconstruct archaeological artefacts using digital technologies and to visualize them in an immersive experience in Virtual Reality. The focus of the project has been the reconstruction and 3D ...
Augmented Reality for Sculpture Stability Analysis and Conservation
(The Eurographics Association, 2020)
Augmented reality (AR) technology has provided museum visitors with more immersive experiences, but it has yet to reach its full potential for the conservators and historians who craft the exhibits and protect their cultural ...
ICAT-EGVE 2020 - International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments
