r-cran-misc3d 0.9-0-1 (amd64 binary) in ubuntu hirsute

 This CRAN package provides a collection of miscellaneous 3d plots, including
 rgl-based isosurfaces:
 .
  contour3d Uses rgl 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.
 .
  lines3d Draws connected line segments in an rgl window.
 .
  parametric3d Plots a two-parameter surface in three dimensions in
                rgl. 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.
