Now I'm expanding the limits of my vector based library. I'm trying to "stress" it and construct new operations based on it.
I'm coding "filling" functionalities using vector operations. My vector based algorithm can fill 99% of the pixels for degenerated curves like that showed in the picture. Probably I could achieve 100% for any curve using antialiasing operations. However, filling is already a very expensive operation. I don't think antialias overhead is worthy in this case.
Filling algorithms are a very interesting subject in CG by itself. This problem can have many derivations depending on if you are rendering, drawing, making masks, etc.
A good software must have a rastering based filling too. It doesn't matter how powerful or hardware enforced your vector based library is, sometimes you just don't have a vector based representation of what you want to fill.
Since filling is my subject for now, I'm thinking about to code a raster filling now (putting the vectors aside for a while). People with some experience in CG can think: "Very easy, huh? You just need to have a recursive function like [SetPixel]
Do you really think it's a good choice? I will give my opinion about that in next post.
