Re: [Quantlib-dev] Surface interface

[Joseph W. <jo...@gn...>]

There is something that would be very useful would be if you could find or 
point me to an example using VTK or mayavi which draws a surface and a 
scatterplot using the python interface.

VTK has a really steep learning curve, and if you can post "hello world" in 
VTK that would be very useful.

Thinking though the design a bit.  What I was thinking of doing is to use the 
TimeSeries template and create a TimeSeries of sampled curves or a TimeSeries 
of functions.  This could then be inserted into an interpolator which would 
return a surface which could be plotted by an external function.

There also may be a need for a Curve object that does the same thing as 
Surface (i.e. provide an external standard interface for 1-d objects).  Curve 
would require an Interval.

The way that I was thinking of moving forward was to create a TestSurface 
object which just plots a 2-d sinusodial function.  Get the SWIG bindings 
working, and then try to use that Surface to plot a hello world surface.  
Once I can see what I'm doing, then we can attach the Surface object to the 
rest of QuantLib and start ploting volatility surfaces or interest rate yield 
curves.
