    • Automatic Step Size Relaxation in Sphere Tracing 

      Bán, Róbert; Valasek, Gábor (The Eurographics Association, 2023)
      We propose a robust auto-relaxed sphere tracing method that automatically scales its step sizes based on data from previous iterations. It possesses a scalar hyperparemeter that is used similarly to the learning rate of ...

    • Parallel Loop Subdivision with Sparse Adjacency Matrix 

      Wang, Kechun; Chen, Renjie (The Eurographics Association, 2023)
      Subdivision surface is a popular technique for geometric modeling. Recently, several parallel implementations have been developed for Loop subdivision on the GPU. However, these methods are built on complex data structures ...

    • Tight Bounding Boxes for Voxels and Bricks in a Signed Distance Field Ray Tracer 

      Hansson-Söderlund, Herman; Akenine-Möller, Tomas (The Eurographics Association, 2023)
      We present simple methods to compute tight axis-aligned bounding boxes for voxels and for bricks of voxels in a signed distance function renderer based on ray tracing. Our results show total frame time reductions of 20-31% ...

    • Luminance-Preserving and Temporally Stable Daltonization 

      Ebelin, Pontus; Crassin, Cyril; Denes, Gyorgy; Oskarsson, Magnus; Åström, Kalle; Akenine-Möller, Tomas (The Eurographics Association, 2023)
      We propose a novel, real-time algorithm for recoloring images to improve the experience for a color vision deficient observer. The output is temporally stable and preserves luminance, the most important visual cue. It runs ...

    • Velocity-Based LOD Reduction in Virtual Reality: A Psychophysical Approach 

      Petrescu, David; Warren, Paul A.; Montazeri, Zahra; Pettifer, Steve (The Eurographics Association, 2023)
      Virtual Reality headsets enable users to explore the environment by performing self-induced movements. The retinal velocity produced by such motion reduces the visual system's ability to resolve fine detail. We measured ...

    • Text2PointCloud: Text-Driven Stylization for Sparse PointCloud 

      Hwang, Inwoo; Kim, Hyeonwoo; Lim, Donggeun; Park, Inbum; Kim, Young Min (The Eurographics Association, 2023)
      We present Text2PointCloud, a method to process sparse, noisy point cloud input and generate high-quality stylized output. Given point cloud data, our iterative pipeline stylizes and deforms points guided by a text description ...

    • Is Drawing Order Important? 

      Qiu, Sherry; Wang, Zeyu; McMillan, Leonard; Rushmeier, Holly; Dorsey, Julie (The Eurographics Association, 2023)
      The drawing process is crucial to understanding the final result of a drawing. There has been a long history of understanding human drawing; what kinds of strokes people use and where they are placed. An area of interest ...

    • PointCloudSlicer: Gesture-based Segmentation of Point Clouds 

      Gowtham, Hari Hara; Parakkat, Amal Dev; Cani, Marie-Paule (The Eurographics Association, 2023)
      Segmentation is a fundamental problem in point-cloud processing, addressing points classification into consistent regions, the criteria for consistency being based on the application. In this paper, we introduce a simple, ...

    • CLIP-based Neural Neighbor Style Transfer for 3D Assets 

      Mishra, Shailesh; Granskog, Jonathan (The Eurographics Association, 2023)
      We present a method for transferring the style from a set of images to the texture of a 3D object. The texture of an asset is optimized with a differentiable renderer and losses using pretrained deep neural networks. More ...
