Dear Mario,
I'm very interested in these new features.
I don't know if you remember that last year we had a discussion on the
mailing list, where I was asking if there was a way to plot on
arbitrarily directed y-axes. I had a look to the page you linked
above, draw() has now very very good features, and seems to make it
possible all I need.
I will try to use these new functions in my program as sson as
possible, and let you know.
Thank you
Stefano

>> * Syntax for option 'enhanced3d' has been extended, keeping

>>
>> * Support for terminal SVG (Scalable Vector Graphics).
>> http://www.telefonica.net/web2/biomates/maxima/gpdraw/svg
>>
>> * draw functions now accept lists of options and graphic objects. That
>> is, once defined
>> a : [color = red, terminal=svg] $
>> b : surface_hide = true $
>> c : [mesh([[1,0,0],[0,1,0]],[[0,0,1],[0,0,1]])] $
>>
>> instead of: apply('draw3d, append(a, [b], c)) $ we can write:
>> draw3d(a,b,c) $
>>

>> Hope you'll find this useful.
