Hi, I'm trying to make sense of the image3d plots in misc3d. Unfortunately I can't find any authors on the help pages of the function to e-mail directly. In the following toy example, I'm puzzled as to why (1) the positions of the image plot on the axes include negative values when I think I've specified all to be 1:3 and (2) the...

The misc3d package provides a small collection of mostly rgl-based functions for 3D data: 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 r...
