CUDA Sparse-Matrix / Conjugate Gradient

In our paper (Mickeal Verschoor & Andrei Jalba (2012). ‘Analysis and Performance Estimation of the Conjugate Gradient Method on multiple GPUs’ (Elsevier Journal of Parallel Computing)) we propose an efficient Block Compressed Sparse Row (BCSR) implementation for Sparse-Matrices processed on (multiple) GPUs using CUDA. Using the proposed layout we can perform a Sparse-Matrix Vector Multiplication (SPMV) …

Efficient and Accurate Collision Response for Elastically Deformable Models

Mickeal Verschoor and Andrei C. Jalba Our paper `Efficient and Accurate Collision Response for Elastically Deformable Models’ is just published in ACM Transactions on Graphics, Volume 38, Issue 2. (pdf) Abstract: Simulating (elastically) deformable models that can collide with each other and with the environment remains a challenging task. The resulting contact problems can be …

Proxy-Based Haptic Rendering for Underactuated Haptic Devices

Daniel Lobo, Mine Sarac, Mickeal Verschoor, Massimiliano Solazzi, Antonio Frisoli, Miguel A. Otaduy Standard haptic rendering algorithms are not well suited for underactuated haptic devices. They compute forces oblivious of underactuation, and then they simply project the resulting forces to the actuated subspace. We propose instead a proxy-based haptic rendering method that computes displacements in the …

Soft Hand Simulation for Smooth and Robust Natural Interaction

Mickeal Verschoor, Daniel Lobo, Miguel A. Otaduy Natural hand-based interaction should feature hand motion that adapts smoothly to the tracked user’s motion, reacts robustly to contact with objects in a virtual environment, and enables dexterous manipulation of these objects. In our work, we enable all these properties thanks to an efficient soft hand simulation model. …
