This package provides a small collection of functions for 3D data:

  contour3d     Uses rgl, standard, or grid graphics to render isosurfaces,
                or three-dimensional contours, computed by the marching
                cubes algorithm.

  image3d       Crude 3d analog of image() using rgl to plot points on a
		three dimensional grid representing values in a three
		dimensional array. Assumes high values are inside and
		uses alpha blending to make outside points more
		transparent.

  parametric3d  Plots a two-parameter surface in three dimensions.  Based
                on Mathematica's Param3D

  slices3d      Uses tkrplot to create an interactive slice view of three or
                four dimensional volume data, such as MRI data.

Additional support functions are available for managing triangle mesh
representations of surfaces rendering these surfaces with lighting and
(minimal) shading in standard or grid graphics.
