[openvrml-develop] Preventing rendering of background

[Philip L. <ph...@ed...>]

Hi all,

I have what is possibly quite a simple problem, but one which has me  
a little baffled.

I have been updating some older code inherited  (using  
openvrml-0.14.3) which draws VRML on top of other pre-existing pixels  
in a window.

Updating this code to OpenVRML-0.16.3, object backgrounds are always  
drawn, overwriting the pixels that I need to display the VRML on top of.

Now that I look at it, I can't figure out how the backgrounds of the  
models were suppressed in the older code.. there is certainly nothing  
explicitly commented as such.

Is there some simple way to suppress drawing of backgrounds, in  
either the browser or viewer?

Cheers,

Phil.
