Quantifying Eventual Consistency with PBS
Eventual consistency is often "good enough" for practitioners given its latency and availability benefits. In this work, we explain this phenomenon and demonstrate...

Bounded Biharmonic Weights For Real-Time Deformation
Changing an object's shape is a basic operation in computer graphics. Our goal is to make the design and control of deformations simpler by allowing the user to...
