DESCRIPTION:Progressing Level-of-Detail Animation for Volumetric Elastodyn
 amics\n\nWe extend Progressive Dynamics [Zhang et al. 2024, 2025] from clo
 th and shells to volumetric finite elements, enabling an efficient level-o
 f-detail (LOD) animation-design pipeline with predictive coarse-resolution
  previews for rapid iteration toward a final high-resolution volumetric el
 astodynamics ...\n\n\nJiayi Eris Zhang and Doug James (Stanford University
 ) and Danny Kaufman (Adobe Inc.)\n---------------------\nMixed Material Po
 int Methods for Stiff Elastoplasticity\n\nOur variant of the Material Poin
 t Method discretizes both the velocity and stress fields over mixed finite
  elements, avoiding the need for repeated costly particle-to-grid transfer
 s within the implicit elastoviscoplastic solve. Our method supports materi
 als ranging from sand and snow to elastic soli...\n\n\nGilles Daviet (NVID
 IA)\n---------------------\nMPM Lite: Linear Kernels and Integration witho
 ut Particles\n\nMPM Lite is a hybrid Lagrangian/Eulerian method that remov
 es particle-based quadrature at solve time. It achieves 15.9 times speedup
  over implicit MPM, and 1.88 times speedup over explicit MPM.\n\n\nXiang F

 ego); Yunuo Chen and Chang Yu (University of California Los Angeles); Hao 
 Su (University of California San Diego); Demetri Terzopoulos (University o
 f California Los Angeles); Yin Yang (University of Utah); Joe Masterjohn a
 nd Alejandro Castro (Toyota Research Institute); and Chenfanfu Jiang (Univ
 ersity of California Los Angeles)\n---------------------\nTube Maps: Fast 
 SPH Boundary Handling with Tubular Coordinates\n\nWe introduce Tube Maps, 
 a drop-in replacement for SPH boundary density computation that achieves a
 ccuracy comparable to implicit methods while dramatically reducing their c
 omputational cost. Our key observation is that the boundary density integr
 al is fully determined by the local surface geometry n...\n\n\nDaria Nogin
 a and Silvia Sellán (Columbia University)\n---------------------\nLow-Rank
  Koopman Deformables with Log-Linear Time Integration\n\nWe present a Koop
 man operator method for fast deformable simulation using Dynamic Mode Deco
 mposition, enabling efficient long-term prediction without sequential time
  stepping. Our discretization-agnostic formulation generalizes across shap
 es and resolutions, making Koopman-based reduced models pract...\n\n\nYue 
 Chang (University of Toronto); Peter Yichen Chen (University of British Co
 lumbia); Eitan Grinspun (University of Toronto); and Maurizio M. Chiaramon
 te (Reality Labs Research, Meta)\n---------------------\nPhysics-Inspired 
 Procedural Texturing of Extremely Deformable Surfaces\n\nApplying texture 
 maps to dynamic deformable surfaces presents a significant challenge, due 
 to ever-shifting differences in length scales involved. \nWe present two n
 ovel wave-based procedural texturing algorithms which reproduce common phy
 sical properties like advection and self-similarity, enabling ...\n\n\nAle
 ksei Kalinov, Mickaël Ly, Christian Hafner, and Chris Wojtan (Institute of
  Science and Technology Austria)\n---------------------\nWoodstock: Intera
 ctive Modeling of Fungal Wood Decay\n\nWoodstock is a novel biophysical si
 mulation framework for fungal wood decay. By tightly coupling rot dynamics
 , wood states, and strand-based mechanics, our method reproduces character
 istic decay phenomena such as fungal colonization, trunk hollowing, wood f
 racturing, and eventual structural collapse...\n\n\nZhanyu Yang (Purdue Un

 ------------------\nSimulation - Interactive Discussion\n\nAfter the summa
 ry presentations, attendees will participate in an interactive discussion.
  Outside the room will be a series of poster boards for authors to gather 
 around with the audience. Authors are invited to bring any material relate
 d to their paper that could instigate further conversation such...\n\n\nIn
