[arriscad] setting surfaces to "both sides opaque?

[Jim Bennett]

Brian,

In the 3D Construction Setup menu there is a setting for 1 sided 
triangles for the various surfaces - top, bottom, sides, etc. Set them 
all to Off.

This setting is saved in an array global variable sr_cp1side(x) where 
the array slots (x) are 0-4.

Note that by setting surfaces to double sided, you double the render 
processing time and power needed as the computer has to consider both 
sides of the surfaces. Example: if you have a box which is 6 sides, with 
1 sided surfaces, the six sides on the outside of the box are rendered 
(assuming the sides are facing out). If 1 sided surfaces is off, both 
sides are rendered and the processor has to render the 6 surfaces inside 
the box (12 total) even though those surfaces will never be seen. I find 
that leaving the 1 sided surface setting on cuts down on display time 
and also a lot of confusion in the model.
