sight analysis

This code shows what is more visible in a space. It works upon a nolli plan in which "sight beams" are cast to colour zones with visibility values.

How does it work?

First we need a nolli plan (tose who shows built surface in black and free areas in white). The software reads the image colour in a grid. If the analized point is black, it moves forward. If the point is white then a ‘dot beam’ is cast within sight stopping when the black is found. The cast dots amount is stored in a coordinate couple.

Finally those values are gathered in squares and rendered as a colour range.
