@JustinMSolomon Glad to see I’m not the only one still wordling! Fantastic job today!

@AaronHertzmann These read like the text that generative image models put on signs have they just been Scottish the whole time 😂

@_TheodoreKim One year I finished up and went to sleep at 9pm. I woke up and the clock said 7 so I thought, great, I’ll get a coffee and a bagel! The coffee shop was empty, and as I sat down they started mopping the floors. I thought huh, that’s weird, and realized it was 7pm! 22 hours asleep!

Check out @DonglaiXiang's cool new @SIGGRAPHAsia 2022 paper on combing learned appearance models with physically-based clothing simulations. Awesome looking results! https://t.co/tAH17usJc7

@topher_batty @ana_dodik @JustinMSolomon @_AlecJacobson TikTok sponsorships to promote publications! *A little dance, points at text bubble* “Adaptive octree simulations” *Makes a funny face at new text bubble* “Not practical, right?” *Smiles and does new dance as exciting music drops and new text bubble appears* “Not anymore!”

@milesmacklin @_AlecJacobson I’ve come across references in mechanics from at least the 1970s! (https://t.co/L3LwShdQXq) but have not yet dived backwards in depth through that literature

[Breannan Smith @BreannanSmith]

@milesmacklin @_AlecJacobson Even before the 2004 paper his 2002 stiffness warping paper had these types of ideas: https://t.co/fShRhVF8gQ

@amirvaxman_dgp @_AlecJacobson R0 is slightly different than local-global. Without dynamics, I agree local-global is just a different optimization strategy (equivalent to replacing ARAP’s Hessian with a Laplacian, Kovalsky’s AQP paper I think?). For a given dt R0 vs R(F) is a different objective at each step.

[Breannan Smith @BreannanSmith]

@amirvaxman_dgp @_AlecJacobson The compute a fixed R0 at the start of each timestep energy is *not* rotaionally variant, I believe. In the context of dynamics this would break angular momentum conservation.

@_AlecJacobson Synthesis? Image, motion, design architechture… But then again understanding is inextricably linked to synthesis, and papers on purely understanding are presented in graphics venues. Practically/cynically: Whatever the ‘community’ feels like reviewing at any given moment.

[ACM / EG Symposium on Computer Animation @SympCompAnim]

The program is up and (completely free!) registration is open for SCA 2021, taking place online from Sept 7-10. Don't miss it!

@_AlecJacobson @_TheodoreKim “Origin” meaning 0 determinant deformation gradient, in this context.

[Breannan Smith @BreannanSmith]

@_AlecJacobson @_TheodoreKim I bet even a less aggressive line search would give a gentle deflation, here. IIRC the inversion avoiding LS *wants* a singularity at the origin or it can lock, this was in the SLIM paper for ARAP. ‘Log-variant’ NH should deflate nicely here with the inversion aware LS, I bet.

[Breannan Smith @BreannanSmith]

@_AlecJacobson @_TheodoreKim Yep, pages 8/9 of https://t.co/EwWe1wjLwZ. Would be curious to see if Stable Neo-Hookean also locks with the inversion avoiding line search!
