Hello, found a script in a toolbar which can be loaded
in rhino3d. It’s named rendertools toolbar and the specific
function I was searching is named the billboard tool.
Apparently every program uses it’s own language.
install the rendertools toolbar, which can be found here:

The Billboard tool is what it is all about,
which is named: V4-RotateMapped.rvb
Run the script, select the billboards, let them face
the camera and render.
Hope this is helpfull.
