code: def computeDistortion(self, eEye, fU, fV):
          
  
          fn = self.function_table.computeDistortion
          pDistortionCoordinates = DistortionCoordinates_t()

docs: Gets the result of the distortion function for the specified eye and input UVs. UVs go from 0,0 in 
          the upper left of that eye's viewport and 1,1 in the lower right of that eye's viewport.
          Returns true for success. Otherwise, returns false, and distortion coordinates are not suitable.
