One of the standard techniques to visualize three-dimensional flow is to use geometry primitives. This solution, when opaque primitives are used, results in high levels of occlusion, especially with dense streamline seeding.... Read more »
This paper presents a procedure for modelling aggregates such as piles that consist of arbitrary components. The method generates an aggregate of components that need to be accumulated, and an aggregate shape... Read more »
The hidden point removal (HPR) operator introduced by Katz et al. [KTB07] provides an elegant solution for the problem of estimating the visibility of points in point samplings of surfaces. Since the method requires... Read more »
We introduce novel multi-scale kernels using the random walk framework and derive corresponding embeddings and pairwise distances. The fractional moments of the rate of continuous time random walk (equivalently diffusion rate) are... Read more »
Stackless traversal algorithms for ray tracing acceleration structures require significantly less storage per ray than ordinary stack-based ones. This advantage is important for massively parallel rendering methods, where there are many rays... Read more »
We deal with subdivision schemes based on arbitrary degree B-splines. We focus on extraordinary knots which exhibit various levels of complexity in terms of both valency and multiplicity of knot lines emanating... Read more »
Recent years have seen increasing attention and significant progress in many-light rendering, a class of methods for efficient computation of global illumination. The many-light formulation offers a unified mathematical framework for the... Read more »
At each shade point, the spherical visibility function encodes occlusion from surrounding geometry, in all directions. Computing this function is difficult and point-sampling approaches, such as ray-tracing or hardware shadow mapping, are... Read more »
Enabling animators to smoothly transform between animated meshes of differing topologies is a long-standing problem in geometric modelling and computer animation. In this paper, we propose a new hybrid approach built upon... Read more »
Single view reconstruction (SVR) is an important approach for 3D shape recovery since many non-existing buildings and scenes are captured in a single image. Historical photographs are often the most precise source... Read more »
