Phong‐Rodrigues Extrinsic Vector‐Field Processing
Computer Graphics Forum, EarlyView.Abstract We introduce a new extrinsic discretization of tangent vector fields on triangle meshes that is continuous, with bounded derivatives that are continuous almost everywhere, supporting pointwise evaluation and integration of differential operators.

General Barycentric Coordinates [PDF]
, 2020 V magistrskem delu obravnavam posplošene baricentrične koordinate s pomočjo katerih lahko zapišemo točko znotraj večkotnika kot konveksno kombinacijo njegovih oglišč.

On Bending in the As‐Rigid‐As‐Possible Deformation Energy
Computer Graphics Forum, EarlyView.Abstract The well‐established As‐Rigid‐As‐Possible (ARAP) energy has various forms. For surface deformation, commonly used energies contain an implicit bending penalty. We present a natural, continuous generalization that incorporates multiple ARAP versions with an implicit, user‐controllable bending penalty.

Attention Based Optimization for 3D Shape Registration
Computer Graphics Forum, EarlyView.Abstract Transformers are sequence‐to‐sequence architectures originally designed to handle structurally rigid and order‐sensitive data, such as text and images. At their core, they exploit the attention mechanism, which is permutation‐equivariant and relies on computing token‐to‐token relationships.

Relativistic Time Transformations between the Solar System Barycenter, Earth, and Moon
The Astrophysical JournalRelativistic corrections are essential for time transformations between geocentric, solar system barycentric, and lunicentric reference systems to account for differences in gravitational potential and relative motion.

CuRast: Cuda‐Based Software Rasterization for Billions of Triangles
Computer Graphics Forum, EarlyView.Abstract This paper presents a CUDA‐based software rasterizer capable of rendering up to a billion unique triangles, or up to 4 billion instanced triangles, in real time at 60 fps on an RTX 5090. By specifically targeting dense, opaque meshes, our approach is able to outperform the native GPU rasterization pipeline in these scenarios.

2D Generalized Barycentric Coordinates
, 2023 This package offers an efficient and robust implementation of 2D generalized barycentric coordinates defined for simple polygons in the plane. If coordinates with respect to multivariate scattered points instead of a polygon are required, please refer to

t‐Regina: Data‐driven Authoring of Free‐form Registration for Cartoon Character Sprites
Computer Graphics Forum, EarlyView.Abstract This paper proposes t‐Regina, a novel iterative scheme that automates the manipulation of grid handles in free‐form deformation (FFD) for deformable registrations of cartoon character sprites. First, we build a data‐driven FFD (dFFD) that enables users to handle locations of FFD handles from lower‐dimensional parameters.

Triangle centres : barycentric coordinates [PDF]
, 2020 In an earlier article we had presented a way to characterize well known triangle centres – by their ‘trilinear coordinates.’ (Ref. 1) In this article we take up another system of characterising triangle centres, where each triangle centre is ...
