GPU-Parallel Constant-Time Limit Evaluation of Catmull-Clark Solids
(The Eurographics Association, 2021)
Subdivision solids, such as Catmull-Clark (CC) solids, are versatile volumetric representation schemes that can be employed for geometric modeling, physically based simulation, and multi-material additive manufacturing. ...
Real-time Indexing of Point Cloud Data During LiDAR Capture
(The Eurographics Association, 2022)
We introduce a software system that is capable of indexing point cloud data in real-time as it is being captured by a LiDAR (Light Detection and Ranging) sensor. Our system extends the popular MNO (modifiable nested octree) ...
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 ...
Fully Automatic Mechanical Scan Range Extension and Signal to Noise Optimization of a Lens-Shifted Structured Light System
(The Eurographics Association, 2021)
Digitization of cultural heritage is of growing importance, both for its preservation for coming generations in the face of looming dangers of natural decay or intentional destruction, and current generations, that ...
Fine-Grained Memory Profiling of GPGPU Kernels
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
Memory performance is a crucial bottleneck in many GPGPU applications, making optimizations for hardware and software mandatory. While hardware vendors already use highly efficient caching architectures, software engineers ...
Alignment and Reassembly of Broken Specimens for Creep Ductility Measurements
(The Eurographics Association, 2022)
Designing new types of heat-resistant steel components is an important and active research field in material science. It requires detailed knowledge of the inherent steel properties, especially concerning their creep ...
Reconstructing Bounding Volume Hierarchies from Memory Traces of Ray Tracers
(The Eurographics Association, 2022)
The ongoing race to improve computer graphics leads to more complex GPU hardware and ray tracing techniques whose internal functionality is sometimes hidden to the user. Bounding volume hierarchies and their construction ...
Profiling and Visualizing GPU Memory Access and Cache Behavior of Ray Tracers
(The Eurographics Association, 2022)
Graphical processing units (GPUs) have gained popularity in recent years due to their efficiency in running massively parallel applications. Recent developments have also adapted ray-tracing algorithms to the GPU, where ...
Automated Classification of Crests on Pottery Sherds Using Pattern Recognition on 2D Images
(The Eurographics Association, 2022)
Manual classification of artefacts is a labor intensive process. Based on 2D images and 3D scans of - for example - ceramic shards, we developed a pattern recognition algorithm which automatically extracts relief features ...
Massively Parallel Adaptive Collapsing of Edges for Unstructured Tetrahedral Meshes
(The Eurographics Association, 2023)
Many tasks in computer graphics and engineering involve unstructured tetrahedral meshes. Numerical methods such as the finite element method (FEM) oftentimes use tetrahedral meshes to compute a solution for complex problems ...
