i tried using your suggestion but still can't manipulate the dimensions such

i tried your suggested method. as you can see, there's still a lot of white
space around it.
is there anyway i can:
a) output to png ONLY the 3d chart, NOT the a screenshot of the whole
window? or
The rgl.snapshot function will only save the whole window.
b) set the dimensions of the 3d chart so it COMPLETELY fills the window such
that there won't be any white space? or
You can zoom in to eliminate the white space, but since the outline of
your figure is not rectangular, you'll lose things like the axes and
edges of your figure.
c) anyway to crop pictures in R?
R isn't an image editor, but I imagine you could convert an image into
an array, select a subset of the array, and then convert back to an
image. But you'd be better off cropping in an image editor.

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 smaller than the
window).
I know how to set the size of the window, but not the chart. When I make
the
window smaller, the chart automatically resizes so it gets even smaller.
Is
there a way to set the chart output size so it fills all (or most) of the
window?
Open a window, resize it to the look you want (the right button resizes),
then save the par3d("zoom") value into r3dDefaults$zoom. That will be the
default zoom for new windows you open using open3d. (You may also want to
save par3d("userMatrix") into r3dDefaults$userMatrix, if you want to change
the orientation of the default view.)
