We just released version 4 of the Yocto/GL graphics library. github.com/xelatihy/yocto… This releases focuses on making the library significantly simpler to use while keeping most the features developed so far.

the Cut Locus is the closure of points having multiple shortest paths from a given source. Many differential quantities used in our algorithms are well defined everywhere but at the CL, making it necessary to explicitly define this structure

we can produce a topologically correct and geometrically accurate version of the CL on discrete meshes of any size and complexity, also being orders of magnitude faster than prior art

in the paper we show applications involving the definition of the maximal injectivity disk for the exponential map, and for POV-aware mesh cutting for texturing

this is a joint work with cino and Enrico Puppo, from University of Genoa. PDF of the paper open source C++ code video presentation will be released soon.... stay tuned!

Today we have presented “Practical Computation of the Cut Locus on Discrete Surfaces” at Symposium on Geometry Processing, a joint work with cino and Enrico Puppo. The source code and the presentation are now available at ggg.dibris.unige.it/papers/SGP21_c…

SGP '22 Graduate school starts today! It will stream here: youtube.com/channel/UCVcpk…

Today at Symposium on Geometry Processing I will present our paper on how to efficiently trace Bézier curves on surface meshes. This is a joint work with Giacomo Nazzaro , Fabio Pellacini, @Enrico_Puppo. See you there!

This Thursday at #SIGGRAPH2022, we will present PAVEL, an algorithm that enhances surfaces with detailed deformable decorations found in real-world ceramics. You can find the paper here pellacini.di.uniroma1.it/publications/p… [1/n]

This Thursday at #SIGGRAPH2022, we will be presenting GeoTangle, our work on generating tangle patterns on surfaces. This is joint work with Giacomo Nazzaro and @Enrico_Puppo. You can get a preprint from pellacini.di.uniroma1.it/publications/g…. [1/n]

We just released version 4.4 of the Yocto/GL library. github.com/xelatihy/yocto…. This release includes an experimental CUDA path tracer together with small improvements. This release will be the last one in the 4.x line. Expect major improvements, and changes, in the next release.

The International Geometry Summit 2023 (IGS'23) will feature a poster session. If you have research proposals, recent work or relevant preliminary results of ongoing projects, IGS'23 is the perfect spot to present your work! Call for posters: igs2023.imati.cnr.it/igsposter.html

Happy to announce that our paper "Computing the Riemannian center of mass on meshes" has been accepted to GMP 2023 and is avalibale online at authors.elsevier.com/a/1g%7EEkcAOr6…. This is a joint work with @Enrico_Puppo. See you at IGS'23 in Genova!

Provably injective mappings to convex or star-shaped domains can be computed by means of only triangle splits, edge flips and segment intersections. It took me more than 5 years to complete this article and what I am proud the most is its simplicity arxiv.org/abs/2305.11552
