Converted this script to unity: Basic Illumination Model by andalmeida<\/a>.<\/p>\n

Problems \/ info:<\/strong>
\n– Converted most of the values to floats.. because Mathf.Max() didnt like doubles.. i guess could had made some extension to it.. (maybe thats why there are some artifacts)
\n– Specularity didnt work at first, but there was new code clip in the comments section of that link ^
\n– Rendering is currently done with invidual setpixel()’s on a plane..(texture size 200×200)<\/p>\n
