Personally, overpic is my ultimate latex cheat code. I even ended up having a 0px png to get a global coordinate system in the all page… 😈

(+1 for tikz btw)

With a simple CSVβ€”one recipient per line with their detailsβ€”you can easily create template messages to generate drafts mails to review in Mail.

No webapp, no fancy service. You stay in control.

This is a fantastic program for people of underrepresented genders in the graphics (and hci/graphics) research space. Please share with your network and gently bully your colleagues and advisees into applying. Deadline March 27, application package is fairly light!

I may have the same setup, except for the iconic 2017 mug ;)

Super happy and honored to share that our paper "BSP-OT: Sparse transport plans between discrete measures in log-linear time" won a *Best paper award* at SIGGRAPH Asia 2025!

If you are here, come see my presentation about this work Wednesday afternoon!

Many thanks to the award committee!

TD;DR: The GRSI encourages authors to share code and data, allowing others to reproduce their published results. Papers that meet the criteria receive a "replicability stamp," as recognition for transparency and reproducibility supported by major publishers, journals, and conferences in the field.

Glad to share with you the release 2.1 of the UniformToolKit utk-team.github.io/utk/

UTK is a C++ and Python library to generate and analyze sampling patterns for numerical Monte-Carlo integration (eg. for path tracing algorithms).

You can still use tricks. Eg fixing a max number of samples and optimising OT + progressivity for previous points, or use tile-based approaches projet.liris.cnrs.fr/polyhex/), or change the model/ energy (clamping in GBN or progressive Poisson disk), but you won’t get the same quality.

Oh I see… I missed the pointset vs sequence thing.
So yes having BN sequences could be hard depending on your mathematical BN model you consider. Top quality ones (GBN or OT based) rely on a global energy which may by incompatible with progressively generating samples.
