persp3d and rgl.viewpoint for rotating 3D plots
Dear R-users,
within the rgl-package, I would have a question about the usage of persp3d in combination of rgl.viewpoint.
I am not able to figure out how to let a 3D plot rotating around likewise the example in ?rgl.viewpoint. It seems that when I use persp3d(...) I see something on my screen, which is different from what I get when it's rotating. Is there any different behavior between

rgl: axis/viewport/box problems in persp3d()
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

two plots side-by-side with persp3d(rgl)
Dear R-users,
I would like to place two 3D plots side-by-side in a rgl-setting. It would nice to have something like "par(mfrow=c(1,2))" for basic plots, or an array framework for wireframe(lattice) (see example below). I only managed to overlap two persp3d plots.
My final idea would be to animate both surfaces using play3d(rgl).
Thanks in advance for any help.
Best,

rgl persp3d bounding box color problem.
Hi guys,
I hit on a problem when I use rgl.
Could you try to run the code here in this link and see why the first persp3d gives a red bounding box and the second shows black?

zlim not working in persp3d
Hi list,
I'm trying to limit the z axis plotted using persp3d {rgl} to a given
range. I'm trying the following statement
persp3d(g0,pa,D, xlim=range(g0),ylim=range(pa), zlim=range
(zbounds),col="lightblue")
where g0 and pa are both a range of 20 numbers from 0.05 to 1, and D
is a 20 x 20 matrix with values ranging from 0 to 30000. I'm trying
to set a cap on the Z

RGL plot : lighting problem when triangle3d and persp3d are used in the same plot
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

Correct scaling of axis in persp3d plot
Hi,
I want to format my axis in my persp3d plot.
With my data, which I attached I created a persp3d plot with the following code, which I summarized from different code snippets I found:

Persp3d freezes when run from within Python
G'day everyone,
I've been trying to get an interactive OpenGL plot to work from within
Python 2.6 using Rpy2 and the persp3d function. The problem is that the plot
seems to freeze upon activation. All interactivity is lost even though it
works fine when run from within the R console (version 2.11.1). Is this a
known issue? Any ideas as to what might be causing this, or possibly how to
fix

How to add/draw a persp3d graph to a plot with an existing surface/graph
Dear R users,
I have been trying to draw the following 3d graphs: The solid region bounded
above by the paraboloid z = 9 - x2 - y2 and below by the unit circle in the
xy-plane.
I wanted to visualize the solid region bounded by those two graphs. I could
draw those two 3d graphs separately, but I could not get those two to work
in one single plot.
Here's my code for the paraboloid:

3D-plotting a 2D-matrix that contains z-values (3rd dimension)
Hello,
say I have a 2D-matrix (indexed by x and y), which contains
z values, which I want to plot over x-y.
Either dotted, or if possible as a landscape.
I tried around with persp and plot3d (from rgl)
and persp3d (from rgl).
I sometimes get something that looks good and a while later, when
trying some new data I need to worry about that again.
Is there something lika a convenience function

overlaying points and lines on a surface3d rgl plot with axes
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

movie3d in rgl object 'movie' not found

axes3d/bbox3d - axis values not fixed
Hello,
I'm using the rgl package and plotting a plot with it. I'd like to have all
the axes values auto-hide, but I want to plot a series of characters instead
of the values of the measurement for 2 of the axes. So in the end I will
have one axis (z actually) behave per normal (auto-hide) and I'd like the
other two axes to be custom character vectors that auto-hide.

Legend text -- discrepancy between X11 and postscript
Hi,
When I place a legend on a plot it looks exactly as I intended
on the screen. However, almost always, when I export this to
postscript file, the legend's text protrudes through the legend's
frame (the latter being placed correctly).
See the appended example code. I can send the EPS file as well
for those that are interested (<4 kb; <200 lines).

Using Ruby on Rails to Create Historical Blog
Hi, everybody.
For a long time I''ve been interested in putting together a blog-like Web
site where I write "posts" on historical events and then the posts are

they describe.
I first had the idea because I thought it would be really easy to just

Animation for pers3d
Hello all,
I use persp3d from the rgl-package to plot a sruface. The typical call
is persp3d(x, y, z)
With cooridinate-vectros x, y and a function-values matrix z.
Now I have different z's, say z_1,...,z_n
Question:
Is it possible to generate an animation from a sequence of such calls,
for different z's?
I would like to see how the surface is beeing changed in the time.
Thank you

Rgl and plotmath symbols (via sprites): a trial
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"),

3d plot of earth with cut
Good to hear you've made such progress. Just a couple of comments:
- You should use points3d() rather than rgl.points(). The latter is a
low level function that may have unpleasant side effects, especially
mixing it with other *3d() functions like persp3d().
- There are several ways to draw a flat surface to illustrate your data.
Which one to use really depends on the form of data.
