[R] rgl::writeWebGL( , prefix = , )
Dear all,
I am using writeWebGL to create an HTML page containing an interactive 3D plot.
It works fine with the default prefix="" but fails when I specify a
prefix "for different scenes displayed on the same web page" (quoting
?writeWebGL). I'm sure I'm misreading the help, and would appreciate
guidance.
Briefly, it works fine with the default writeWebGL( ,prefix="", ) and
the template containing %WebGL%
I have not been able to make it work with any other value of prefix; e.g.
writeWebGL( ,prefix="A",) and the template containing %AWebGL%
Here is code illustrating the problem.
First create three templates:
a) Vanilla: copied system.file(file.path("WebGL",
"template.html"), package="rgl") to file.path(getwd(),
"template.html")
b) First attempt: ?writeWebGL says # "[the template] should contain a
single line containing paste("%", prefix, "WebGL%"), e.g.
%WebGL% with the default empty prefix"
paste("%", "A", "WebGL%")
# [1] "% A WebGL%"
so file.path(getwd(), "templateA.html") is a copy of (a) replacing
%WebGL% with % A WebGL%
c) Second attempt: file.path(getwd(), "templateB.html") is a copy of
(a) replacing %WebGL% with %AWebGL%
then, in R
#-----------
library(rgl)
plot3d(1:5, 1:5, 1:5) # generate rgl scene
#-----------
# a) vanilla
writeWebGL(dir=getwd(), template = file.path(getwd(),
"template.html"), prefix="")
# works OK; result opens and works in IE
#----------------
# b) First attempt, my reading of ?writeWebGL
writeWebGL(dir=getwd(), template = file.path(getwd(),
"templateA.html"), prefix="A")
# Error in writeWebGL(dir = getwd(), template = file.path(getwd(),
"templateA.html"), :
# template ?m://templateA.html? does not contain %AWebGL%
# so it looks as if the help is trivially wrong, it should be paste0
paste0("%", "A", "WebGL%")
# [1] "%AWebGL%"
#----------------
# c) second attempt using %AWebGL%
writeWebGL(dir=getwd(), template = file.path(getwd(),
"templateB.html"), prefix="A")
# runs without error in R but IE displays "You must enable Javascript to
view this page properly."
#--------------
I don't understand why (c) is different from (a).

Thanks Duncan, your suggestions led me to a solution.
Perhaps this could be reflected in the help, but I'll leave that
decision to you.
It comes down to the template. As well as including a single line for
each scene containing
paste("%", prefix, "WebGL%"); e.g. %WebGL% or %AWebGL%
the <body > tag must contain an onload attribute with an element for
each scene
paste0(prefix, "webGLStart();")
e.g. <body onload="webGLStart(); AwebGLStart();">
While I'm suggesting additions to the help, it took me a little while to
work out that when writing multiple scenes the result from one
writeWebGL was the template for the next. E.g. in the above example with
two scenes:
outfile <- writeWebGL(dir=getwd(), template = file.path(getwd(),
"template.html"), prefix="")
# position to next scene
outfile <- writeWebGL(dir=getwd(), template = outfile, prefix="A")
Thanks for your help (and a really nice package!)
