[Visualpython-users] povexport and New VPython

[<Art...@rs...>]

First the good news -  

Could be my imagination, but there seems to me to be a *significant*
boost in performance with VPython running on Python21 and 
related Numeric.

Then the less than good - 

On running and clicking on povexample.py I get:

Traceback (innermost last)
  File "c:\python21\programs\demos\povexample.py", line 46, in ?
    code = povexport.export(display=scene, include_list = inclist)
  File "c:\python21\programs\demos\povexport.py", line 334, in export
    object_code = function(obj)
  File "c:\python21\programs\demos\povexport.py", line 157, in export_curve
    frame=a.frame, visible=0)
TypeError: function not supported for these types, and can't coerce to 
supported types

a)  Does this problem duplicate for others.

b) If so, anybody have a clue??

c) Notice tangentially that I get another level of traceback when I run it in 
my usual
text editor 
    "c:\python21\visual\__init__py  line 58 in __call__
        return apply(self.constr, args, kw)"
That seems to be where the bounce out is.

Thanks for any help.

In the mean time I shall play.

Yes, this is reproducible; thanks for reporting it.  
There is a new version of povexport.py on the web site that contains a
workaround, as well as a change by Markus Gritsch to allow "shadowless=1"
as a keyword in the export function.

(The error is caused by attempting to assign an array to object.color -
apparently this is no longer allowed.)

Ruth - 

Thanks  - but half a shucks.  I had proudly tracked 
it down and reported a fix - but my message - 
below didn't post up for some reason.

Nonetheless I shall download the official povexport.

Thanks particularly for doing povexport.  By my lights
as important contribution to VPython.
