In addition to his own research contribution, Sunil manages a small research group in Adobe’s Advanced Technology Labs (ATL).
His team focuses on the use of high-performance computing, available in desktops and notebooks (and tablets), to develop design paradigms and user experiences of the future.
Some specific topics that the group focuses on are:
- Animation — Inverse Kinematics, Skinning, Articulated Rigid Bodies
- Simulation — Fluid Simulation, Viscoelastic Lattice-Boltzmann Simulation for Oil Paint, Rigid Bodies, Deformable Models & Cloth, Physically Based Curve Design
- Computational Imaging — PDEs for Image Enhancement, Super-resolution, Inverse Problems in Image Processing, Deblurring and Defocus, Depth from Defocus, Lighting Estimation, Intrinsic Images, Shape from Shading, Image Relighting
- Multi-CPU and GPU computations, Parallel Algorithms, Scheduling and Cache Performance
The research included 9 research internships, 6 university collaborations, 3 PhD topics. Product groups have shown a keen interest in these technologies. Initiatives such as image relighting, intrinsic images and shape estimation push the boundaries of computational imaging and are poised to revolutionize aspects of digital photography and content creation.
Under his leadership, consultation & mentoring, and through my direct research contribution, he shipped the following flagship product features
- Graphics Math Library (GML), a SSE optimized small vector-matrix-quaternion library, CS4, CS5
- Inverse Kinematics and Skinning, Flash Pro CS4
- Physics for Flash, Flash Pro CS5
- Bristle Brush, realistic simulation of artist’s brush on canvas, Photoshop & Illustrator CS5
You must have wondered how they did the hair in “Shrek The Third”, the foliage in “Madagascar”, and recently hair in “How to Train Your Dragon”. Before joining Adobe, he worked at PDI/DreamWorks for four years (2003-2006) developing some cool special effects and character dynamics technologies — strand & hair dynamics, rigid bodies, particles and fluids.
He finished his PhD from MIRALab, University of Geneva in 2003.
