Background color in 3D Graph Window

[goetz]

I don't know of a direct way, but have some code for this (run this function setplotbg on the home screen when 3D graphing app is selected).The function below should change the colour to white, and inside RGB in the third line you can set the colour by red, green, blue value (0 to 255). It sets a 1 pixel background picture in stretched mode.

However, it seems the built-in 3D graphing app overlays this with some own background, so it is actually a light grey.

PHP Code:

EXPORT setplotbg()
BEGIN
DIMGROB(G1,1,1,RGB(255,255,255));
AFiles("bg.png"):=G1;
ImageName:="bg.png";
ImageDisplay:=2;
END; 


You can quickly revert to black by going to the plot setup (shift+plot) and on the 5th page disable the background image.
