About

Andrei Sharf is a leading researcher in computer graphics and geometry processing, with a focus on 3D shape reconstruction, dynamic modeling, and data-driven acquisition techniques. His work bridges the gap between physical principles and computational methods, most notably through the "Dip transform for 3D shape reconstruction" (2017, 15 citations), which reimagines Archimedes’ fluid displacement principle as a novel approach to acquiring and reconstructing three-dimensional shapes. By repeatedly submerging an object in liquid at different orientations and measuring volume displacement, Sharf’s method generates robust geometric data from sparse, noisy inputs—a breakthrough for applications in cultural heritage, manufacturing, and robotics. In "Mobility Fitting using 4D RANSAC" (2016, 12 citations), he tackles the challenge of capturing articulated motion from incoherent dynamic data, enabling the functional analysis of moving objects like humans and mechanical systems. Sharf’s contributions are distinguished by their creativity and practicality, often introducing physical analogies to solve computational problems. His work has been recognized for its impact on shape acquisition and motion analysis, earning him a reputation for innovative, cross-disciplinary thinking that inspires both students and researchers in geometry processing and beyond.
