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 b...

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,
Carlo Giovanni Camarda

Correct scaling of axis in persp3d plot

How to add/draw a persp3d graph to a plot with an existing surface/graph
...isualize 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:
x <- seq(-10, 10, length= 30)
y <- x
f <- function(x,y) { 9-x^2-y^2 }
z <- outer(x, y, f)
persp3d(x, y, z, aspect=c(1, 1, 1), col = "lightblue",
xlab = "X", ylab = "Y", zlab = "9-x^2-y^2")
And my code for the cylinder with the unit circle as the base:
z <- matrix(seq(0, 1, len=50), 50, 50)
theta <- t(z)
x <- cos(theta*2*pi)
y <- sin(t...

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?
http://rafb.net/p/g1i7ur33.html
(sorry for not pasting the code here directly but my previous email got filtered by this list so I suspect my code looks like spam to the spam filter)
I'm expecting black color to be the right result but the...

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...

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 it?
cheers,

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 are two "holes", one in (0,0,1) and one
in (1,1,0); how can I fix that?
Cheers,
Marius

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?

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 that
can be used to feed the data into persp, rgl::plot3d and rgl::persp3d?
At least persp3d is picky about the orde...

Question about persp3d label direction
Hello, R experts
I am a new user of rgl package.
I want axis label to be parallel to the axis.
However, I cannot find any options in package manual.
Could you show me how to how to make label be parallel to crresponding axis.
Especially, Z axis label, in case that it is long, protrudes out of the plot and invades the plot.
Please, let me know. I spent every night and day of even a month.

3D Graph Surface and single points (eg wireframe with points)
...allo!
?
I just want to make a 3D plot of a surface of a cone and want to plot some single points around.

I tried wireframe but cannot find how to plot single points
?
I tried scatterplot3d but there the surface is not simple to plot. And: How can I rotate the point of view by the z-axis
?
I tried persp3d but how can I add some single points?

Example:

d$z <- sqrt((d$x-4)^2 + (d$y-10)^2)

3d graph to show matrix of z matrix values
Hello,
I'm not getting a great looking 3d graph when plotting my z values:
x <- seq(0.0, max(d1), max(d1)/20)
y <- seq(0.0, max(d2), max(d2)/20)
z <- matrix(NA, length(x), length(y))
persp3d(x, y, z, phi=30, theta=30, scale=TRUE,shade = 0.75,
col=pal[col.ind], xlab=var.name[1], ylab=var.name[2], main="3d plot")
Are there other options like persp3d where I can just plot my z-values along
the x and y axis??
Thanks in advance
