Radial basis functions (RBFs) are important in computer graphics, with widespread use in reconstruction, animation, etc. In pose space deformation (PSD) [Lewis et al. 2000], RBFs are used to perform shape interpolation for pose-driven deformations. The behavior of an RBF depends on its particular definition. For artists, the relationship between definition and behavior is not intuitive. We suggest a method for artists to better understand RBF behavior through visualization and to evaluate RBF functions according to the requirements of a production environment.
