Release 0.4-0 of package misc3d is now available from CRAN. This package provides a small collection of functions for 3D plotting, including 'contour3d' for computing and rendering 3D contours or isosurfaces and 'parametric3d' for rendering parameterized surfaces. A major change in this release is that rendering in standard and grid graphics is now supported in addition to rgl. To support rendering in standard and grid graphics the package includes some functions for managing and rendering triangle mesh representa...

Dear R users -- I think this question was asked before but there was no reply to it. I would appreciate any suggestion any of you might have. I am interested in plotting several "implicit functions" (F(x,y,z)=0) on the same fig. Is there anyone who has an example code of how to do this? Thank you Yihsu

...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. -- Luke Tierney Chair, Statistics and Ac...

Dear all; I'm tring to find a way to plot a solid of revolution in R, say rotating the 3 param logistic function aaround the x-axis. Is there a way to do it using R? Thanks for any hint PM
