Question about contour3d and writeWebGL: rgl and misc3d package
I saw that in rgl:::writeWebGL that "Polygons will only be rendered as
filled; there is no support in WebGL for wireframe or point rendering.". I
found that you can easily use contour3d to make reproducible contour web
figures, such as (taken from contour3d help)
library(AnalyzeFMRI)
a <- f.read.analyze.volum...

3d interactive video using the rgl package
Hi all,
I've been using the 'rgl' package to visualise in 3d the water temperature recorded by a glider deployed off the coast of Australia (see snapshot attached). Using the writeWebGL function, I'm able to produce an html file of the scene with which I can then interact (e.g. zoom in/out, rotate) in my web browser.
In R, I have created another scene that includes a loop plotting the movements of the glider with the time. Is it possible to export that whole animation with th...

exporting 3D dynamic graph
Hi the list,
Using misc3d, we can export 3d dynamic graph in pdf format.
Is it also possible to export these graph into a format that we can publish on the web?

positioning a light source within a rgl-plot
Hello useRs,
I would like to draw a 3D-surface using rgl with a point-like
light-source within the scene, that is with finite distance of the
light-source to the surface to be lit.
>From the help to the 'light3d' command I read:
"They [the light-sources] are positioned either in world space or
relative to the camera using polar coordinates."
which *could* be understood as

Transform plot3d grafics in to executable files
Hello,
I did some nice grafics using plot 3d and scatter3d. Is there a,
hopefully not too complicated way, to transform these dynamic,
three-dimensional and interactive grafics in a kind of
executable file? I want to show and send them via e-mail to projekt
partners who don`t use GNU R and who are not used to do programming.
So the result should be quite comfortable to execute for them in

In-string variable/symbol substitution: What formats/syntax is out there?
Hi,
I'm try to collect a list of methods/packages available in R for doing
in-string variable/symbol substitution, e.g. someFcn("pi=${pi}"),
anotherFcn("pi=@pi@") and so on becomes "pi=3.141593". I am aware of
the following:
** gsubfn() in the 'gsubfn' package, e.g.
> gsubfn( , , "pi = $pi, 2pi = `2*pi`")
[1] "pi = 3.14159265358979,
