An introduction to trajectory optimization: How to do your own direct collocation

M Kelly - SIAM review, 2017 - SIAM
This paper is an introductory tutorial for numerical trajectory optimization with a focus on
direct collocation methods. These methods are relatively simple to understand and …

Add: Analytically differentiable dynamics for multi-body systems with frictional contact

M Geilinger, D Hahn, J Zehnder, M Bächer… - ACM Transactions on …, 2020 - dl.acm.org
We present a differentiable dynamics solver that is able to handle frictional contact for rigid
and deformable objects within a unified framework. Through a principled mollification of …

Interactive simulation of rigid body dynamics in computer graphics

J Bender, K Erleben, J Trinkle - Computer Graphics Forum, 2014 - Wiley Online Library
Interactive rigid body simulation is an important part of many modern computer tools, which
no authoring tool nor game engine can do without. Such high‐performance computer tools …

Example-based elastic materials

S Martin, B Thomaszewski, E Grinspun… - ACM SIGGRApH 2011 …, 2011 - dl.acm.org
We propose an example-based approach for simulating complex elastic material behavior.
Supplied with a few poses that characterize a given object, our system starts by constructing …

Sampling-based contact-rich motion control

L Liu, KK Yin, M Van de Panne, T Shao… - ACM SIGGRAPH 2010 …, 2010 - dl.acm.org
Human motions are the product of internal and external forces, but these forces are very
difficult to measure in a general setting. Given a motion capture trajectory, we propose a …

Synthesis of detailed hand manipulations using contact sampling

Y Ye, CK Liu - ACM Transactions on Graphics (ToG), 2012 - dl.acm.org
Capturing human activities that involve both gross full-body motion and detailed hand
manipulation of objects is challenging for standard motion capture systems. We introduce a …

Fluid directed rigid body control using deep reinforcement learning

P Ma, Y Tian, Z Pan, B Ren, D Manocha - ACM Transactions on Graphics …, 2018 - dl.acm.org
We present a learning-based method to control a coupled 2D system involving both fluid
and rigid bodies. Our approach is used to modify the fluid/rigid simulator's behavior by …

Near-exhaustive precomputation of secondary cloth effects

D Kim, W Koh, R Narain, K Fatahalian… - ACM Transactions on …, 2013 - dl.acm.org
The central argument against data-driven methods in computer graphics rests on the curse
of dimensionality: it is intractable to precompute" everything" about a complex space. In this …

Three-dimensional motion planning algorithms for steerable needles using inverse kinematics

V Duindam, J Xu, R Alterovitz… - … Journal of Robotics …, 2010 - journals.sagepub.com
Steerable needles can be used in medical applications to reach targets behind sensitive or
impenetrable areas. The kinematics of a steerable needle are non-holonomic and, in two …

Deformable object animation using reduced optimal control

J Barbič, M da Silva, J Popović - ACM SIGGRAPH 2009 papers, 2009 - dl.acm.org
Keyframe animation is a common technique to generate animations of deformable
characters and other soft bodies. With spline interpolation, however, it can be difficult to …
