FastSweeping.h | Defined the six functions {fog,sdf}To{Sdf,Ext,SdfAndExt} in addition to the two functions maskSdf and dilateSdf. Sdf denotes a signed-distance field (i.e. negative values are inside), fog is a scalar fog volume (i.e. higher values are inside), and Ext is a field (of arbitrary type) that is extended off the iso-surface. All these functions are implemented with the methods in the class named FastSweeping |
