similar to: misc3d Contour export to vtk

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=

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:

Hi, I have a question about exporting interactive 3D plots. I use the following code to plot a contour of a trivariate normal distribution: library(mvtnorm) library(rgl) library(misc3d) n=25 x=seq(-3,3,length=n) X=cbind(rep(x,each=n**2),rep(rep(x,each=n),n),rep(x,n**2)) p=array(dmvnorm(X,sigma=diag(3)*0.5+0.5),c(n,n,n)) contour3d(p,x,x,x,level=mean(p)) lim=c(-3,3)

has there been any attempt to improve the 3D visualization (interactive) features in R, using the vtk library? It seems fairly straight forward. maybe even trivial for somebody who has experience with vtk library. let me know if there are any obvious reasons i may have overlooked thanks, in advance for any feedback -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

Hello, I've written a short code (below) to write 3D unstructured grid to binary VTK files from R. Problem : I can only write integers with the command : data<-as.numeric(c(3.3)) storage.mode(data)<-'integer' writeBin(data,bfile_celldata,endian="swap") the function storage.mode(data)<-'long' looks fine, but the VTK file is not readable. thanks for any

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.

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

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]]

Hello, I know this is maybe not the right mailinglist but hopefully anyone can help me anyway. I need OpenGL for VTK. The problem is, that I am not able to install the NVIDIA driver for the xen kernel. Is there any other possibility to get OpenGL or does anyone know how to get VTK running on a xen kenerl machine? Maybe there is a patch for the driver I did not find yet? Regards, Markus --

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

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

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.

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

http://cornwarning.com/xfer/test.cxx.gz This is a preprocessed version of a file from from the VV image viewer package. I stripped out all the lines beginning in '#' and multiple empty lines. It's about 75k lines of code. On a Mac Pro, the unix 'time' command says it's using 249 seconds of user time. Wall time on my machine somewhere around 5 minutes? 249.035u 1.883s

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
