EROS-DOCK: Coarse-grained rigid docking with exploration of 3D rotational space
EROS-DOCK is a coarse-grained docking approach that uses the physics-based ATTRACT scoring function in conjunction with a quaternion « pi-ball » representation of 3D rotational space. The pi-ball allows over 95% of candidate docking poses to be eliminated trivially due to steric clashes, thus allowing the remaining non-clashing orientations to be calculated very efficiently. In this way, the approach combines the exhaustive coverage of classical FFT-based approaches with an « exact » high quality scoring function.
EROS-DOCK was written by Maria Elisa Ruiz Echartea, with some contributions from Dave Ritchie.

Hex: FFT-based rigid docking
Hex is a very fast protein-protein and protein-ligand docking program developed by Dave Ritchie. It uses a spherical polar correlation technique to accelerate the docking calculations. Hex can exploit highly parallel modern graphics processor units to achieve a further significant speed-up. Overall, Hex is up to three orders of magnitude faster than conventional FFT-based docking algorithms.
