Thank you for your work on rgl. Reading in another thread about your new (inofficial) version of rgl (see below) I tried it with R version 2.5.0 alpha (2007-03-31 r40986) under FreeBSD 7.0-CURRENT. Unfortunately I got the following error: ------- #R CMD INSTALL rgl_0.70.570.tar.gz * Installing to library '/usr/local/lib/R/library' * Installing *source* package 'rgl' ...

Hello, I very much enjoy rgl! But when converting the screen output to pdf using rgl.postscript I have encountered three problems: (1) I don't seem to have control over font sizes and point sizes (of added points) in the pdf output. I tried cex from "plot" but that does not have an effect. Initially I got some plots where fonts and especially points were far too small. But now

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,

For a paper dealing with generalized ellipsoids, I want to illustrate in 3D an ellipsoid that is unbounded in one dimension, having the shape of an infinite cylinder along, say, z, but whose cross-section in (x,y) is an ellipse, say, given by the 2x2 matrix cov(x,y). I've looked at rgl:::cylinder3d, but don't see any way to make it accomplish this. Does anyone have any ideas? thx,

Dear Roger Koenker, I have had just the same problem (rgl.snapshot returns "failed") on my Fedora Core 6 system. It took me quite a while to figure out the solution, so I would like to post it here to make others' lives easier.

Does anyone have a way of producing solid shapes other than spheres in rgl? I am using rgl to produce a simple visualisation of a forest model results using "lollipops". Its just a bit of fun, but as many of the trees are pines I would like to depict their crowns as cones. If there is a solution I need it to work under windows. Here is the example. library(rgl) library(misc3d)

Dear all, I have tried to plot a triangular matrix with the function persp3d(rgl). for example z=rbind(c(1,NA,NA,NA),c(5,3,NA,NA),c(4,2,9,NA),c(8,6,5,11)) x=1:4 y=1:4 persp3d(x,y,z,color="gray") The two extreme points are not plotted (value=1 and value=10). It seems because the half of the matrix have 'NA' and perp3d need planar quadrilateral face. So I decided to use the

Dear list, I'm trying to visualise some ellipsoidal shapes in 3D. Their position, axes, and angular orientation can be arbitrary. I saw an ellipse3d function in rgl; however it is heavily oriented towards the statistical concept of ellipse of confidence, whilst I am just concerned with the geometrical object. Below is my current implementation. It is quite slow when creating many shapes, so

Dear all, The documentation on the function open3d in the rgl package, reads: open3d opens a new rgl device, and sets the parameters as requested. I want the new rgl device (window) to be sized and positioned in a specific place on my screen. So, I try to set the "windowRect" parameter as follows: > library("rgl") > open3d(windowRect=c(100,100,500,500))

Dear R-Help Team, I have been trying to sort (all columns of) a matrix: > a<-matrix(a<-c(1,3,4,6,6,4,6,56,4,64,86,39,4,2),length(a),2) > a [,1] [,2] [1,] 1 1 [2,] 3 3 [3,] 4 4 [4,] 6 6 [5,] 6 6 [6,] 4 4 [7,] 6 6 [8,] 56 56 [9,] 4 4 [10,] 64 64 [11,] 86 86 [12,] 39 39 [13,] 4 4 [14,] 2 2 > I

Hi, I don't know much about the RGL package, and I have read the documentation and tried some parameters, with no luck... I would like to generate a movie from a 3D object (code below), where the vortex A is closer to the observer, and then the object rotates and the B vortex gets closer. I would like to capture this movie to a file. By the way, I am not being able to insert unicode text

Dear r-helpers, Can one save a dynamic graphic produced by rgl, e.g.: open3d(); x <- sort(rnorm(1000)); y <- rnorm(1000); z <- rnorm(1000) + atan2(x,y); plot3d(x, y, z, col=rainbow(1000), size=2) as a dynamic figure that can be embedded in a pdf? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400

Hi all, I just started using the rgl package in R, and I need to know how I connect the dots I created. A simple line from one co?rdinate (x0,y0,z0) to another (x1,y1,z1) will do. I tried using the code rgl.lines, but it doesn't accept lines that don't stem from O (0,0,0). Please help! Thanks! -- View this message in context:

I'd like to use rgl.surface (or some other function if more appropriate) to create a horizontal and vertical transparent grey slice (plane) running through both the x and y origins and extending across the z axis, i.e. the 3-d equivalent of the normal 2-d coordinate axes we are all familiar with. The examples for rgl.surface are a bit more complex than what I need and I am having trouble

I'm trying to use the rgl package on R-2.7.1 running on top of Ubuntu Hardy amd64. using open3d() and plot3d() I get a plot, but it is not interactive. Furthermore, changes to par3d("FOV"=my.new.value) do nothing. I suspect something is wrong with the rendering engine or interface to it. I do have an Nvidia driver installed and compiz works correctly on the desktop. I've

Hi all, How can I tell RGL to set the center for the rotation to the origin of the coordinate system (0,0,0). It seems that the default is to use the center of the display not the origin of the coordinate system. open3d() lines3d(c(0, 1), c(0,0), c(0,0)) lines3d(c(0,0), c(0, 1), c(0,0)) lines3d(c(0,0), c(0,0), c(0, 1)) TIA Mark ???????????????????????????????????????

Dear Rglers, With rgl, I would like to set marker when a button is pressed, but leave the standard trackball handling otherwise. Thanks to Duncan and Oleg for helping me handling key down. How do I say in a custom mouse handler "after having done your work, forward to standard trackball once only"? The example below shows the idea, but it works only once, then reverts to standard

Hi, I'm using rgl to generate a 3D surface plot and I'm struggling to get the lighting correct. Currently the surface gets plotted, but is very 'shiny'. On rotating the view, I get to see parts of the surface - but overall I don't see much detail because of the spotlight like lighting. I've played around with the specular, ambient and diffuse but I can't

I want to print characters from the symbol font (or perhaps even Wingdings) in an rgl 3d plot, but I am having no luck. So, what do I have to do in order to get this snippet to print out a character from the symbol font? library(rgl) open3d() text3d(1,1,1,"a",adj=c(0.5,0.5),cex=10,family="symbol",font=1) I am on Windows XP with R 2.9.1.

Last week I asked about data ellipses with rgl:::ellipse3d() with lines showing the principal axes. (The goal is a visual demonstration of PCA as a rotation of variable space to component space.) I was trying, unsuccessfully, to use princomp() to generate the PCA axes and plot them using segments3d: > > PC <- princomp(trees) > > sdev <- PC$sdev # component standard
