Hello All,
Try this little big of code:
from visual import *
a=helix()
print a.color
I notice that the color for each segment is returned as a numpy array. This
is actually quite fun, since you can individually set the color along the
helix, but leads to problems matching colors between objects, for instance:
a=helix()
b=sphere()
b.color=a.color
This gives the error:
Traceback (most recent call last):
File "<pyshell#17>", line 1, in <module>
b.color=a.color
ArgumentError: Python argument types in
None.None(sphere, numpy.ndarray)
did not match C++ signature:
None(class cvisual::primitive {lvalue}, class cvisual::rgb)
So, I would propose that somehow we preserve the ability to access the color
array, say through an attribute "helix.colorarray" or something, but that a
single color gets returned with the helix.color attribute.
