I actually think that's the most important thing to have. Without a
"draw curve" tool, the rest of the tools would be unlikely to be used
by anyone.

However, I think the stuff that Tim is doing for tools will end up
helping there.
Okay, I'll have to talk to Tim about that then, but I'd really like to see this feature.

I think a plugin/modifier would be best here. User select's the CVs
that should have their multiplicity changed, and applies the modifier.
It would have a property/spinner that would control the multiplicity
of the points it affected.
Hmm, if you have 3 CVs which had different multiplicity, should they be changed to the same value or to the same amout?
Well if you'd select one CV with this tool you might change it to your needs but.. Hum perhaps a boolean which of the two ways to choose?

The couple of sections above are an example of how k3d really shines.
Even though its got a lot of unfinished areas, the foundation allows
for so much. It's cool that those things have pretty much already been
supported in the back end.
True, there's really much potential in the backend, and thats exactly what we GSoC students are there for: get the most out of it!


I'm confronted with another issue here: I just noticed that if I merge two CVs and remove the points from the mesh::points vector, I need to change all indices referring to the points.. Is there any better way to do this? Or should I just let the unused point in there not being referenced?
I dont think the latter is a good idea, but the most easy one :).

Cheers,
Carsten
