similar to: Exporting interactive 3D plots with axes and labels

I am looking for examples of how to plot with contour3d() to a PNG or PDF file, add axes and other elements to the isosurface plot, and use contour3d in conjunction with lattice. Regarding lattice, I'm not necessarily looking for conditioning on the data shown in the isosurface plots, just a way to show multiple plots in one figure and label them. I am new to the packages misc3d and rgl.

Hey, Is there any function plotting several "implicit functions" (F(x,y)=0) on the same fig. Is there anyone who has an example code of how to do this? The contour3d function in the misc3d package only work with the functions with three dimensions. Thanks a lot. Many thanks for your help. KnifeBoot [[alternative HTML version deleted]]

I'm making some 3D plots with contour3d from misc3d and wireframe from lattice. I want to view them from below; i.e. the negative z-axis. I can't figure out how to do so. I would like my point of view looking up from below, with the z, y, and x axes positive going away. Can anyone tell me the correct settings for screen to achieve this? Here is what I've found so far:

So I wanted to export a contour3d object into VTK and it worked well enough, except the top of the ball (the contour) was missing. Example below, or gist here: https://gist.github.com/muschellij2/5126544 rm(list=ls()) require(misc3d) f <- function(x, y, z) x^2+y^2+z^2 x <- seq(-2,2,len=20) ball <- contour3d(f,4,x,x,x, draw=FALSE) drawScene.rgl(ball) ### get the triangles allids

Hello everybody, I would like to solve the problem described below in R (if possible). I am very new to R and have therefore no idea what to even look for in the docu. Therefore, if someone could tell me if this is possible in R and where I might find the respective docu then I would already be very thankful. I have a large set (a few million) of points in 3D. I would like to create a

I saw that in rgl:::writeWebGL that "Polygons will only be rendered as filled; there is no support in WebGL for wireframe or point rendering.". I found that you can easily use contour3d to make reproducible contour web figures, such as (taken from contour3d help) library(AnalyzeFMRI) a <- f.read.analyze.volume(system.file("example.img", package=

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

Hi, I am trying to install the misc3d package on a Windows (XP) installation of R 2.0.1 using install.packages("misc3d") but with no success. I have used this approach with other packages OK, but for misc3d I get the following output... trying URL `http://cran.r-project.org/bin/windows/contrib/2.0/PACKAGES' Content type `text/plain; charset=iso-8859-1' length 27996 bytes

Hi, When plotting the density estimation with DrawDensity3D-function (in package VecStatGraphs3D) it often happens that the end product ie. layers are not intact , see figure in the link: https://www.dropbox.com/s/vzyaiu0vso8hjw2/20623868_10213333234554853_1371245353_n.png?dl=0 Can we somehow effect on that an get intact layers? -- Atte Tenkanen

Hi all, How do I visualize a contour of a tri-variate normal distribution? I just like to see the ellipsoid very much. I hope there is a easy way or existing method in R. Thank you a lot! Michael. [[alternative HTML version deleted]]

Hi the list, I would like to draw some lines with misc3d. I find a lot of tools to draw surfaces, but nothing for simple line... Is it possible? Note that I know that it is possible to draw lines with rgl (using lines3d), but I need to do it with misc3d to export the drawing in .asy format. Any solution? Christophe

Hi the list, I use rgl to produce a 3D graph. I would like to "show" this graph to some collaborator. Is there a way to save it and send it to someone else? Christophe Genolini

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 logic that needs to be adhered to in order to

Suppose there are 4 variables d is a function of a , b and c I want to know how a, b and c change will make d change It will be straightforward to see it if we can graph the d surface if d is only a function of a and b, I can use 'persp' to see the surface of d. I can easily see at what values of a and b, d will get the maxium or minium or multiple modes, etc But for 4 dimention graph,

I have what is probably a noob question, but.... I am trying to create a 3d plot to illustrate the range of values for the following simple function: A = B*(C/D) B, C, and D are independent variables whose range are equal (e.g. 1 to 3 inclusive) I figure it's not possible to map the surface of A on the 3d space defined by B, C and D but I would like to create a surface defined by the

Hej, When plotting triangles with rgl.triangles and setting the axes afterwards with decorate3d(aspect=TRUE), the axes get the color used for the last triangle plotted. Example: rgl.triangles(c(1,2,3),c(1,2,5),c(1,3,2),col="#55FF55") decorate3d(aspect=TRUE) Using decorate3d(aspect=TRUE,col="#000000") or decorate3d(aspect=TRUE,color="#000000") does not help,

How can I eliminate the border drawn by default around a wireframe plot? I've tried using border=NA and box=FALSE to no avail. Scott Waichler Pacific Northwest National Laboratory scott.waichler at pnl.gov

Hi the list, Using misc3d, we can export 3d dynamic graph in pdf format. Is it also possible to export these graph into a format that we can publish on the web?

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.
