Write observed locations to VTK.
Write the observed points to a VTK file.
writeObservedLocationVTK(move.dat, mkde.obj, description, filename, control)
move.dat |
A move data object created with |
mkde.obj |
An MKDE object created with |
description |
A text description for the file header |
filename |
A string for the path and file name |
control |
A list for finer control |
Writes 3D points for observed locations for move steps. Currently, the
list argument control only has one element z.scale used to scale the
z-coordinates.
