What is Picture to People ?
"Picture to People" (P2P) is a huge Computer Graphics project. It was started to create new softwares able to make 2D drawing, 3D rendering, vexel drawing, text effects, photo effects, image filtering and other complex Computer Graphics operations. It has been made from scratch, including its low level Computer Graphics libraries like Maccala. Nowadays, most final features produced for this project are released as free online tools available from its official website. This blog talks about Computer Graphics, mainly concerning Picture to People development.

Drawing curves with progressive thickness
Now it's possible to create any kind of curve with an arbitrary progressive thickness. I guess it's kind of strange I have never developed this before, but I have never needed something like this until now.
Surprisingly, it was harder to develop than I imagined initially. It was needed to redevelop my algorithm responsible for creating a thick shape based on a Math curve (conceptually a curve has no thickness at all).
In fact, in a generic algorithm, even drawing operations (in this context, "draw" means "render the contours") are tackled as filling jobs. First an assembling algorithm constructs a shape with an arbitrary thickness, so a filling algorithm can render it.
Below you can see a curve drawn with variable thickness. Now it's possible to make something like this so easily as calling a method. Unnecessary to say, the professional anti-aliased rendering is still there.
