Spent about half an hour to do experiments and finally get a program to convert to regular panorama to small-world style.
The key is coordinate system transform, from rectangular to polar. This is pretty intuitive …
[Update2] I used the library eigen to reimplement the algorithm, reducing the code from 84 lines to 41 lines (wow), and time increases 11%. Looks acceptable, with similar workload as unoptimized C#, but the same speed as heavily optimized C# (with 164 lines of code and unsafe compilation). What's even …
Finally time for an upgrade of our Beamer Writer. I added two features recently.

I find it also useful in our daily research, say, to host a paper reading seminar. (I assume you are …
I was interested in F# because of some of its fun usages, and the ease to do asynchronous and parallel computing. Used F# to implement some domain specific language like Turtle and fractal effect this afternoon. Basically the tasks themselves are nearly the same as this post and this post …
