R help - Apr 2017 - Larger rgl-images?

Hi,

In package ?VecStatGraphs3D? is a DrawDensity3D-function in which the 
rgl-device size is defined as
r3dDefaults$windowRect=c(0,0, WSizeWidth, WSizeHeight).

To save, for instance, a png-snapshot, we can use rgl.snapshot()-function.

The size of the file is dependent on the window and thus your screen and 
video card.

Can we somehow produce  larger images virtually, for example, 4k-images 
(3840x2160)?

I don't know of a way to do that.  If you can create a virtual screen of 
that size, and your system allows you to create a window on it, then it 
might work:  but I haven't come across a way to do that that also 
supports OpenGL in the virtual window.
