Now, here I am, standing with uncertain feeling and half of confidence. I must finish this puzzle “Pattern Drawing”, the idea of research which I am almost sure (but I can not be sure) that no one ever worked in it.

Here I am, bringing a piece of unclear map and old-tired brain, ready (?) to fight in battle, to build correct solution of the puzzle. The map is all I have as guidance for exploring big forest in front of me, where pieces of puzzle’s answer be located. I need to pick pieces of correct answer and arrange all of them together. On the map, I can see clearly only three pieces “tensor product b-spline surface”, “wavelet based multiresolution representation of tensor product b-spline surface”, and “subdivision surface”, but other pieces are dark; the map doesn’t tell me where they are located. I don’t know whether the 3 pieces of answer are the correct answers of my puzzle or not; and I must explore the dark forest to find other pieces. The puzzle is big and difficult. Can I solve it?

Here I am, smiling and almost crying. No one help me. No one give me guidance “what pieces I should take”, “which way in the forest I should take to pick the correct pieces”, “how I should arrange the pieces”. Why do they give me unclear map? Why do they not give me a candle that I can bring to explore the dark forest? It seems that my study is “my own” problem. I even don’t know who “they” are.

Here I am, with no other choice except “just do it”. Uuuhhh …. Then,“Bismillah”. I’ll explore the forest.

*My puzzle is describing a method for drawing patterns on multiresolution surface along a set of user-defined curves, which allows easily features creation on surface just like drawing a sketch in 2D using a palette of patterns.
