similar to: [rgl] Dynamically change the color of 3d objects

I am trying to figure out how to use rgl package for animation. It appears that this is done using the play3d() function. Below I have some sample code that plots a 3D path and puts a sphere at the point farthest from the origin (which in this case also appears to be at the end of the path). What I would like to do is animate the movement of another sphere along the length of the path

Dear all, I have a question about the plotting of the dynamical orbit by using rgl. My code is as follows: open3d() par3d(cex=2) bg3d("white") for(i in 1:out.length){ ind<-which plot3d(x[1:i],y[1:i],out[,"z"][1:i],xlim=c(-10,10),ylim=c(-10,10),zlim=c(-10,10),col="red",cex=2) Sys.sleep(0.0001) } ,where x,y,out[,"z"] are the position of the object in

I want to plot points with different colors to show different selections of points in a 3d plot. My problem is that if I plot a red point at a location where already a blue point was plotted, than the point is still blue. Is there a parameter or so which can be used to draw over a existing point? Example: > require(rgl) > open3d() > plot3d(a<-c(1,2,3,4,5),a,a,type="l",

Hi, I am trying to compare two 3D plots. For that, I am trying to use the "pch" parameter in the "points3d" function, but it is not working. Is it implemented? Any suggestion? Here goes a reproducible code. I wanted the second plot having different symbols for the points. x <- rbind(matrix(rnorm(100, sd = 0.3), ncol = 2), matrix(rnorm(100, mean = 1, sd = 0.3),

Is there a way to change the viewpoint using view3d (or rgl.viewpoint) with respect to the image that currently appears rather than the perspective that rgl thinks is the default? For example, if I create an image and then perform what should be a no-op: rgl.viewpoint(userMatrix=rotationMatrix(0,1,0,0)) the image is rotated. Then I can perform rotations on the result without surprises. But I

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

After interacting with a 3d plot (eg plot3d, persp3d), is there a way to capture the final settings of view angles, etc, so that the final plot could be easily reproduced? The plot functions themselves just return a vector of 'ids'. -- View this message in context: http://r.789695.n4.nabble.com/rgl-reproduce-final-state-of-interactive-plot-tp3667866p3667866.html Sent from the R help

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, 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))

Doing a visual graphic and trying to make it "pretty" Here's simple chart to play with: library(rgl) dotframe<-data.frame(x=c(0,7,0,0,-7,0),y=c(0,0,7,0,0,-7),z=c(7,0,0,-7,0,0)) dotframe plot3d(dotframe$x,dotframe$y,dotframe$z, radius=3, type='s',col=c('red','green','blue','purple','orange','gray'), axes=FALSE, box=FALSE,

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

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,

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 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, 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 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

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

Hi R users and experts, I am interested in learning more about the use of 3D plots. Specifically, I want to add points and lines to a surface plot. And get the axes and labels plotted also. Here is what I have tried with an example data set : library(rgl) vol2 <- 2*volcano # Exaggerate the relief library(reshape) mvol2 <- melt(vol2) str(mvol2) # First, persp and persp3d plots do not succeed

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,

Hello, I've CCd' Duncan Murdoch as the rgl maintainer, but I'm also keen to hear from the broader community of any insights. In rgl my understanding is that there's only one rotation-navigation mode, where you left-click hold and the view pivots abound the centre of the scene. In other tools, including Google Earth, that is the default behaviour but there's also a
