Computing Skinning Weights via Convex Duality
Computer Graphics Forum, EarlyView.We present an alternate optimization method to compute bounded biharmonic skinning weights. Our method relies on a dual formulation, which can be optimized with a nonnegative linear least squares setup. Abstract We study the problem of optimising for skinning weights through the lens of convex duality.

The inverse problem to the Voronoi diagram
, 2007 The primary purpose of this thesis is to address the problem of solving the Inverse Problem for the Voronoi Diagram where the Inverse Problem is: Given a diagram that is in fact a Voronoi Diagram find the set of points X = {x1, x2, x3,…,x n} in R2 that ...

FluidMap: Proportional and Spatially Consistent Layout Enrichments in Multidimensional Projections
Computer Graphics Forum, EarlyView.FluidMap faithfully represents the frequency of an attribute and preserves spatial consistency. Current space‐filling methods over‐ or under‐represent attribute categories (i.e., all Voronoi‐based methods), sacrifice spatial consistency (i.e., Nmap) or both (i.e., Voronoi‐MWα).

A Survey of Methods for Constructing 3D Urban Models From Point Clouds
Computer Graphics Forum, EarlyView.The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Smart Structures across the Voronoi diagram
Proceedings of the International Conference of Contemporary Affairs in Architecture and Urbanism-ICCAUA, 2019 Nowadays computational geometry plays a fundamental role in a large number of domains, it solves geometric problems by using algorithms through several parameters intricated between them; one of those domains is construction in view of its geometrical ...

Controllable Intrinsic Surface Pattern Generation Using Slime Mold Simulations
Computer Graphics Forum, EarlyView.Abstract Surface‐based pattern simulations have proven valuable for texture design and scientific visualization, but existing methods face several limitations. Most simulations either target a narrow range of pattern types (e.g. spots, branching) or support a broad range of patterns at the cost of time‐consuming parameter tuning.
