Repairing Inconsistent Curve Networks on Non-parallel Cross-sections
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
In this work we present the first algorithm for restoring consistency between curve networks on non-parallel cross-sections. Our method addresses a critical but overlooked challenge in the reconstruction process from ...
A New Microflake Model With Microscopic Self-shadowing for Accurate Volume Downsampling
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Naive linear methods for downsampling high-resolution microflake volumes often produce inaccurate appearance, especially when input voxels are very opaque. Preserving correct appearance at all resolutions requires taking ...
Fast Catmull-Rom Spline Interpolation for High-Quality Texture Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
It is well known that cubic texture filtering can be efficiently implemented on the GPU by using a method published by Sigg and Hadwiger [SH05], which simplifies the evaluation to a linear combination of linear texture ...
Cosine-Weighted B-Spline Interpolation on the Face-Centered Cubic Lattice
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Cosine-Weighted B-spline (CWB) interpolation [Csé13] has been originally proposed for volumetric data sampled on the Body-Centered Cubic (BCC) lattice. The BCC lattice is well known to be optimal for sampling isotropically ...
DMAT: Deformable Medial Axis Transform for Animated Mesh Approximation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Extracting a faithful and compact representation of an animated surface mesh is an important problem for computer graphics. However, the surface-based methods have limited approximation power for volume preservation when ...
