Our paper "Shrink & Morph: 3D-printed self-shaping shells actuated by a shape memory effect" was accepted to SIGGRAPH Asia! We print flat plates with controlled trajectories so that, when heated, they morph into pre-programmed shapes

@GladiaLab Looks like some heavy inspiration from @keenanisalive's figure...

LLMs are injective and invertible. In our new paper, we show that different prompts always map to different embeddings, and this property can be used to recover input tokens from individual embeddings in latent space. (1/6)

@gkopanas @runwayml Congrats! Will you be staying in London?

Small life update: Just joined @runwayml , quite excited to work on video models and figure out tools for creative artists in the modern era.

New year, new review! Thanks Abigail Struhl (@a_struhl) for our first publication of 2025 🎉. Check out this striking review of Marie NDiaye's "Vengeance is Mine" here: chicagoreview.org/marie-ndiaye-v…

In nature, one life ends when another begins. Material degradation becomes functional repurpose and upgrade, mediating natural ecology. A new project from @MorphingMatLabled by @Dr_Qiuyuand Semina Yi, @BerkeleyME @Cal_Engineer @UCBerkeley morphingmatter.org/projects/dtf

@quent_becker Congrats! Looks very cool ;)

Super fun project to work on with great collaborators! See you in Tokyo 😊

@xavierchermain Nice!

I harvested this beautiful post reflection on morphing matter from the lens of a junior yet brilliant computer graphic student, Sergius, who attended my talk at Summer Geometry Initiative led by @JustinMSolomon at MIT. summergeometry.org/sgi2024/explor…

Proud of you! (By the way this guy's on the job market 😉)

I started decorating my lab desk using multi-color printing!!🐻

About 10 years ago, I benefited from my first student volunteer work at CSCW in Hangzhou. SV gives one not only a free registration, but also a life-long experience, friendship and community. We need you for #UIST2024, student volunteers!

"Differential Geometry" by Pinkall & Gross is Open Access. You can get it at: link.springer.com/book/10.1007/9…

@StavrosDiol Congrats Stavros!

Time to share our #SIGGRAPH2024 paper "N-Dimensional Gaussians for Fitting of High Dimensional Functions"! We show that N-Dimensional Gaussian mixtures can be optimized to handle high dimensional inputs like MLPs with a fraction of the training times. sdiolatz.info/ndg-fitting/

In this week's #PeopleofACM, we profile Adrien Bousseau, a Senior Researcher @Inria. Bousseau's interests include image creation and manipulation, shape modeling and scene understanding. Read the full interview here: bit.ly/42AyXAo #computing #imagecreation #modeling

@amir_zadpoor @MJMirzaali @moosabeiki1 affecting expansion factors, because their printers were able to extrude fast enough without introducing gaps in the material. (3/3)

@amir_zadpoor @MJMirzaali @moosabeiki1 This seems to be caused by the increase in porosity observed in the CT scans, and I think this porosity is probably due to the printer not being able to extrude the required amount of material. This would explain why so many papers report they didn't find printing speed was (2/3)

In a recent paper on #4Dprinting (nature.com/articles/s4324…), we show how #3Dprinting defects and multiple materials can be used to create complex #shape transformations and a wide range of Gaussian #curvature @MJMirzaali @moosabeiki1 #additivemanufacturing
