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 ...
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 ...
A NLP Enhanced Visual Analytics Tool for Archives Metadata
(The Eurographics Association, 2020)
Today, almost all cultural heritage (CH) institutions are starting to digitize parts of their collections and archives to improve accessibility, preservation of originals, publicity, and visibility of the institution on ...
Aging Prediction of Cultural Heritage Samples Based on Surface Microgeometry
(The Eurographics Association, 2018)
A critical and challenging aspect for the study of Cultural Heritage (CH) assets is related to the characterization of the materials that compose them and to the variation of these materials with time. In this paper, we ...
CPU-Style SIMD Ray Traversal on GPUs
(ACM, 2018)
In this paper we describe and evaluate an implementation of CPUstyle SIMD ray traversal on the GPU. We show how spreading moderately wide BVHs (up to a branching factor of eight) across multiple threads in a warp can improve ...
Visualizing Networks of Maya Glyphs by Clustering Subglyphs
(The Eurographics Association, 2018)
Deciphering the Maya writing is an ongoing process that has already started in the early 19th century. Among the reasons why Maya hieroglyphic script and language are still undeciphered are inexpertly-created drawings of ...
Compressed-Leaf Bounding Volume Hierarchies
(ACM, 2018)
We propose and evaluate what we call Compressed-Leaf Bounding Volume Hierarchies (CLBVH), which strike a balance between compressed and non-compressed BVH layouts. Our CLBVH layout introduces dedicated compressed multi-leaf ...
A Configurable Design Approach for Virtual Museums
(The Eurographics Association, 2018)
Virtual Museums (VM) are widely used to preserve and to disseminate cultural heritage to the audience, due to the existing evidence that they can enhance the interest on cultural heritage content, while reinforcing motivation ...
