Calling Sequence

...

  
set3_object(drawing_function, [arg1, arg2,...])

Description

Set up to trigger a call to draw3, adding a call to the3D display list of the form:

  
DRAWING_FUNCTION ([ARG1, ARG2, ...]))

When draw3 calls DRAWING_FUNCTION, the external variable draw3_ will be non-zero, so DRAWING_FUNCTION can be written like this:

  
def drawing_function(arg) : if (draw3_) : 
arg1=arg[0] 
arg1=arg[1] 
... 
...< calls to get3_xy, sort3d, get3_light, etc.>... 
...< calls to graphics functions plfp, plf, etc.>... 
return 


...< verify args>... 
...< do orientation and lighting independent calcs>... 
set3_object (drawing_function, [arg1, arg2,...])
