I really do wonder how much of these gaps can be attributed to the universities themselves. Elite universities are more likely to attract successful and motivated and thus will "produce" more successful graduates than other univer

Yeah, I was a bit disappointed that they started focusing on their own renderer instead of just explaining more of the basics of path tracing. Note that it isn't necessary at all to sort rays, although it can make things faster if done

Bidirectional path tracing is one way of sampling paths (actually it combines many techniques for sampling paths and weights those using something called Multiple Importance Sampling). It's not the only way of doing it. Disney most lik

That's very simple: if we don't end up hitting a light the path won't carry any radiance, so it won't contribute to the final image. If we start on a light and we don't end up hitting the camera the path won't

No that's wrong. You do start tracing paths at the camera. The lens usually is extremely small and the rays that do contribute are highly directional, the probability of hitting the lens is extremely low and the probability of the hitt

It's not as fun as agar.io in my opinion. The biggest problem is the balance in this game: in agar.io big players are discouraged from attacking small players, they're too slow to catch them and the risk of splitting is not worth

It's absurd that you have to press on a button called 'Customize' (which is really scary sounding for non-experts) to get any privacy in Windows 10. If users are brave enough to press this button they get a list of nondescrip

I used Tao's books on Real Analysis during college and my feelings are mixed on his capabilities as an educator. On the one hand his books were really great as he gave a lot of proofs (although most proofs were still left to the reader

Yeah, such profiles can certainly be used for skin rendering. I know that SPI used the method you mentioned on a few movies. There will be visible flaws though. The skin and especially the lips will look too waxy when using gaussians or bic

Nope, sadly not. This username was one of the few computer graphics related usernames left on reddit and solid angle sampling is so much cooler than area sampling. You're not only person who thought this, so it's probably about ti

This is already happening: - Sony Pictures Imageworks open sourced Open Shading Language, Field3D, Alembic and OpenColorIO. - Pixar opensourced OpenSubDiv - Disney opensourced Ptex, BRDF Explorer, SeExpr and Partio - Dreamworks open sourced

AFAIK Industrial Light and Magic used Arnold for a lot of movies, Framestore used Arnold for Gravity (I'm not sure what they use now), Double Negative uses a whole range of renderers (with layer between their OSL shaders and the render

Most of those shaders written back then are pretty much worthless now that Renderman has introduced RIS mode (instead of REYES mode), which was introduced last year. Pixar recommends writing shaders in C++ now instead of in RSL, as C++ shad

I'm pretty sure you can't. Let's say you want to render realistic skin using Cycles. You can't, the only BSSRDF profiles that Cycles offer are simple bicubic and gaussian profiles, these wouldn't work for rendering

If you're interested in writing a renderer yourself (which is obviously way cooler than using some tools), I'd recommend first picking up either "Fundamentals of Computer Graphics" by Shirley and Marschner or "Compu

Coming from the land of Dijkstra (the Netherlands), I was taught about this in college and it was very cool to use this to prove that post-conditions of a function are actually true (although finding good loop invariants was sometimes a bit

If anyone is interested in the other papers that are presented at SIGGRAPH 2015, Ke-Sen Huang usually has a complete list with links to preprints and videos. You can find the list for SIGGRAPH 2015 here: http://kesen.realtimerend
