recently i managed to find information on how computer graphics are done nowadays instead of cosine law they are using something called a bdfr or something function for calculating surface lighting also _path tracing has been around for three decades_ frarrgh i've looked so much on the internet for path tracing ever since i learned about it in the 90s and never found anything on it ever and now i just have to go to wikipedia and it tells me everything. i would have really enjoyed path tracing! (path tracing algorithms sound really similar to goal steps solving, a path needs to be found between a start state and an end state and the relations of the middle parts are known, but it's not always the most obvious p, ath, so smart algorithms work from both ends as well as trying good middle candidates) fraaaaaargh so much new graphics stuff i want to learn it all and i'm confused and mentally disabled :( i wonder if path tracing is used in demo competitions i wonder if people are exploring AI like they used to explore graphics algorithms anyway the bdfr-or-something is a function of how much light leaves a surface in a direction depending on the angle it hits, i guess few surfaces are perfectly diffuse also the pathtracing algorithms are slow and grainy on wikipedia because they use random ray sampling o_o i imagine people have tried more frustrum sampling somewhere. you'd do it like adaptive interpolation and approximate curves for the light between the samples if the edges interacted with the same objects (people were doing that for raytracing demos for decades). path tracing :) 1339 1341 :s :s ~
