Dear useRs, I'm trying to simply fill in the area under a curve using RGL. Here' the set up: x <- c(0.75,75.75,150.75,225.75,300.75,375.75,450.75,525.75,600.75,675.75, 0.5,50.5,100.5,150.5,200.5,250.5,300.5,350.5,400.5,450.5, 0.25,25.25,50.25,75.25,100.25,125.25,150.25,175.25,200.25,225.25) y <- c(0.05,4.91,9.78,14.64,19.51,24.38,29.24,34.11,38.97,43.84,

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,

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

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

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

Hi!! I need to draw a cylinder/tube joining two points. I am trying to make something presentable, I have been able to do it using lines3d. But is it possible to increase the thickness of the lines? The size parameter does not work. Does any one have any suggestions? Thanks ../Murli library(rgl) pts<-structure(list(x = c(-0.975688, -0.975688), y = c(9.258795, -9.258795 ), z = c(-1.8, 1.8)),

Hi, I am having an issue when creating a postscript file from RGL window. It seems to cut off some of the axis labels. Here is the code I am using. I created a 3D plot using RGL_0.71 with R 2.5 on Windows XP. z1<-c(5,4,1,4.5,2,3,2,1,1) z2<-c(6,8,7,7.5,5,3.5,4,1,1) z3<-c(3,2,4,7,3,4.5,6,2,3) x1<-seq(1,9) x2<-seq(1,9) x3<-seq(10,18) y1<-seq(8,0) y2<--1*y1

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, 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:

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

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

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

I have a general style question about R coding. Suppose I'm writing a function (foo1) that calls other functions (foo2, foo3, ...) which have complicated argument lists (e.g. optim(), plot()), _and_ I may be calling several different functions in the body of foo1. Since foo2 and foo3 have different sets of arguments, I can't just use "..." ; I did write some code a while ago

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

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)

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 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 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
