Oh thanks.

I choose a beautiful picture, so not very clear what it is.
I upload another picture.
I implement it with Bezier spline, but don't allow user to edit the tangent
handle point, instead it generate the tangent handle points automatically, for
maintain every part of the curve is smooth.

Control the shape of annual ring. instead of perfect circle. Like ... this photo
on gallery:

I start the wood pattern with perfect concentric circles and constant grow
rate(interval of two ring), but it is too inflexible, I want some variety, so I
rewrite it with segmented curve. I don't have too much idea for the color_map
now.

I never thought that, maybe it can transfer to applet after finish, but I focus
on the program itself currently.

Ha ha... that sky render is too big and need too much experiment to improve, I
cannot develop it in this stage. It is far from an one person work.
