Interactive Pixel-Accurate Rendering of LR-Splines and T-Splines
(The Eurographics Association, 2015)
Flexible surface types on irregular grids, such as T-splines and LR-splines, are gaining popularity in science and industry due to the possibility for local grid refinement. We present a novel rendering algorithm for those ...
3D Architectural Modeling: Efficient RANSAC for n-gonal Primitive Fitting
(The Eurographics Association, 2015)
We present a modeling approach to automatically fit 3D primitives to point clouds in order to generate a CAD like model. For detailed modeling we propose a new n-gonal 3D primitive and a novel RANSAC based fitting approach. ...
4D Mesh Reconstruction from Time-Varying Voxelized Geometry through ARAP Tracking
(The Eurographics Association, 2015)
We present a method to derive a time-evolving triangle mesh representation from a sequence of binary volumetric data representing an arbitrary motion. Multi-view reconstruction studios use a multiple camera set to turn an ...
Individual Time Stepping for SPH Fluids
(The Eurographics Association, 2015)
We present a novel adaptive stepping scheme for SPH fluids, in which particles have their own time-steps determined from local conditions, e.g. Courant condition. These individual time-steps are constrained for global ...
Isogeometric Analysis for Modelling and Design
(The Eurographics Association, 2015)
We present an isogeometric design and analysis approach based on NURBS-compatible subdivision surfaces. The approach enables the description of watertight free-form surfaces of arbitrary degree, including conic sections ...
High-Quality Shadows for Streaming Terrain Rendering
(The Eurographics Association, 2015)
Rendering of large, detailed 3D terrains on commodity hardware has become possible through the use of raycasting, data caching and prefetching. Adding dynamic shadows as they appear during a day-night cycle remais a challenge ...
Content-Aware Projection for Tiny Planets
(The Eurographics Association, 2015)
Tiny Planets visualise the world looking down at the ground, with physically unrealisable projections that curve the ground plane to look like small worlds. Whilst certain geometries, such as Stereographic, are known to ...
Separation of Manga Line Drawings and Screentones
(The Eurographics Association, 2015)
Screentones are unique expressions of Japanese comics (manga), which enrich their visual expression. However, such screentones have a very different visual nature from that of line drawing areas; this prevents us from ...
Improving k-buffer Methods via Occupancy Maps
(The Eurographics Association, 2015)
In this work, we investigate an efficient approach to treat fragment racing when computing k-nearest fragments. Based on the observation that knowing the depth position of the k-th fragment we can optimally find the k-closest ...
Target Temperature Driven Dynamic Flame Animation
(The Eurographics Association, 2015)
Fire/flame plays an important role in virtual environment. Controlling the flame behavior in an intuitive yet precise manner remains a challenging open problem. In this paper, a target temperature driven simulation method ...
