\label{iptsshape} The Rho-Kinase inhibitor (sticks) and receptor (surface) from PDB 2H9V shown with the identified interaction points (spheres). Shape constraints derived from this structure. The interaction pointsare  become a minimum shape constraint (yellow) by applying a radius of 1{\AA}. Here the receptor volume has been shrunk by 1{\AA} (two layers of surface voxels were removed) to form a maximum shape constraint (inverse shown in cyan). Voxlized image generated with Sproxel.\cite{sproxel}
