Dear expeRts, I am a new user of rgl, below is my first trial to plot a simple function in 3d. I managed to put the axes in the right locations, but: (1) The xlab, ylab, and zlab arguments are ignored; how can I put in axes labels? (2) Since I removed the axes in persp3d() the viewport is too small; is it possible to keep the size of the viewport? (3) The box is not correctly drawn, there

Context: I have two or more rgl-based views of a given data set, perhaps fitting different models, or showing different things across views. I want to be able to hand-rotate, zoom, scale one view to something I like, and then show the other views with matching viewpoints and scaling. so that one could flip back/forth among graphs and see only the relevant differences. In 2D, all this usually

Dear list, I'm using the function "movie3d" in the package "rgl" to create a .gif animation of a 3d graphic. The program "ImageMagik" is working properly, R packages are working, basic examples available in the manual also working fine. Problem Solved: when I tried to create more complex movies, i.e. combining different views and zooming, the R-console crashed

Dear all: I'm enjoying using rgl and I want to set a specific viewpoint. I understand that view3d() will do so by setting the 3d polar coordinate angles, theta and phi. In standard polar coordinates, theta is the angle away from the X axis in the X-Y plane and phi (inclination angle) is the angle between the Z axis and the radius vector It appears that when you use view3d() theta is

Hello R-users, I have downloaded and installed a binary version for Windows OS of ImageMagick (ImageMagick6.5.6-10-q16-windows-dll.exe), I have installed the rgl package and i've tried running the following example from ?movie3d() library(rgl) open3d() plot3d( cube3d(col="green") ) M <- par3d("userMatrix") play3d( par3dinterp( userMatrix=list(M,

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 ???????????????????????????????????????

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 all, Below is some code where I try to get plotmath symbols in an rgl plot. Duncan Murdoch kindly suggested to use a "sprite" for this. As you can see, on can get it to work, but my knowledge about grid and rgl is too limited to perfectly solve the problem. 1) As you can see (please rotate the plot a little bit so that (0,0,0) is "in front"), the quality of the .png

Hello, I am trying to save a .gif movie using movie3d from the package {rgl}. I am using the following code combined with the globe example on the ?movie3d page. I've installed ImageMagick and the directory seems to be working properly, i.e. when I do Sys.getenv("PATH"), C:\\Program Files (x86)\\ImageMagick-6.7.0-Q16 shows up. #### library(rgl) open3d() lat <-

Hi R users, Does anyone know how to change the size of 3d charts? I'm using surface3d in rgl package, opening a new window each time to display the chart. I want it so that the chart fills the whole window, because when I output it to png, I don't want all the white space around the chart (right now, i'm getting this white "border" around the chart because the chart is

Dear R community (and Duncan more specifically), I can't work out how to make additional light sources work in rgl. Here is the example. First I create a cube and visualize it: > cubo <- cube3d(col="black") > shade3d(cubo) Next I position the viewpoint at theta=0 and phi=30: > view3d(theta=0,phi=30) Next, I want to create a 2nd light source which diffuses red light

Two questions related to creating animated movies with rgl: 1. I've created an rgl scene with 5 different views I want to display in a movie, but I'd like to insert pauses (say, 5 seconds) at each view. How can I do this? I first created 5 userMatrix's, then play3d( par3dinterp( userMatrix=list(M1, M2, M3, M4, M5)), ,duration=2*60/5) ) then tried simply repeating each twice,

Hola a todos: Estoy intentando visualizar unos resultados de un programa en R de forma dinámica. Dichos resultados se pueden representar, básicamente, con un plano que gira sobre uno de sus ejes: para dar sensación de movimiento he utilizado la función rgl.clear(), ya que no encuentro los equivalentes en rgl de los parámetros add o new. El problema es que al limpiar la pantalla con rgl.clear la

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 would like to be able to use play3d() to translate the view along a surface, and zoom in and out. All the examples in play3d() function description are of rotations. I would also like to know if there is a method of creating a legend of for the 3d surface using rgl package. Thanks in advance. Chibisi [[alternative HTML version deleted]]

Dear List, I'm trying to draw vector in XYZ with rgl under use of a cylinder3d. Therefore I scale and rotate a basis-cylinder). However, somehow the rotation is wrong as verified by overplotting arrow3d(). Where is my mistake? library(heplots) library(rgl) # ... 2 vectors data=data.frame(row.names=c('X','Y','Z'), x1=c(2,1,5),y=c(4,3,2))

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- Users, is there a way to determine the size of an rgl window (rgl.open()) either in advance or afterwards, (without using the mouse, of course) ? Intuitively, one would assume to set the size by: library("rgl"); par3d(viewport=c(0,0,500,500)); #rgl.open(); for example. As the parameter 'viewport' is 'readonly' this results in an

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

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
