Octaviz is a visualization system for Octave. It
is a wrapper that makes all VTK classes
accessible from within Octave using the same
object-oriented syntax as in C++ or Python. It
also provides high-level functions for 2D and 3D
visualization. Using those functions, most common
visualization tasks (3D surface plots, contour
plots, meshes, etc.) can be accomplished without
any knowledge about VTK.
