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.

Can a computer draw like a human?

I have been studying and researching about Computer Graphics for more than 15 years. A great part of this time I have spent researching about professional artistic filters and effects.

I was always facinated by the way humans produce art, mainly drawngs and paintings. I have always tried to create math models and algorithms able to make drawings like ones made by human hands.

Now I got closer to my intention. I have created a new model to draw based on photos. Here some of the main reasons that make this algorithm work "like a human":

- the final image is made of thousands of small and delicate strokes (many people are used to draw this way);

- each stroke is carefully chosen (the calculations are made stroke by stroke);

- strokes respect and follow the photo geometry globally (on purpose or not, drawers usually act like that).

Below I show you a simple example. You can easily realize the strokes follow the geometry of the input photo in a similar way many drawers do.
