[@samuelpizzatto8666]

Hey, thanks for the tutorial. Also a great course you mentioned in the description! I hope to see more of those in the future :)

[@georginikoloff9280]

So greatly explained! Thanks a lot

12:14 it is not a linear increase: at an angle of 45 degrees (halfway in between) the dot product is not 0.5. The change is not linear but sinusoidal, it's proportional to the cosine of the angle between the vectors.

Really appreciate it, thanks very much :D

[@glowiever]

light value can exceed one? do we need floating point framebuffer to do that?

[@michaeldamolsen]

@@levuhoangkhai8816 Bui Tuong Phong, a Vietnamese studying at University of Utah, published in his 1973 dissertation "Illumination for Computer Generated Pictures". If you search for the title you can find the whole original document ( a008786.pdf ) and a shorter review article he wrote for ACM in 1975. It is always great to read the original material :) I don't provide links here, as KZbin seems to dislike that lately (causing the comment to end up in review, often without notifying the channel owner.)
