Here is the full list of papers with links to preprints for the papers presented at SIGGRAPH 2018: http://kesen.realtimerendering.com/sig2018.html

RenderMan traces ray streams of a few thousands rays (at least not millions like Disney's Hyperion), right? Does that really help that much with reducing the shading costs? It prob…

Some context: During a panel on production renderers at SIGGRAPH [0] it was mentioned that most rendering research was not really usable for production rendering, as those algorith…

The per-thread caches are not strictly necessary, but you don't want threads to block because they can't stream in geometry to memory. You want some upper bound on the amount of me…

Yup, I meant paging geometry. The problem with just doing a two level BVH is that some models can be very large, while others may be much smaller, which makes it hard to reserve me…

There's very little info in the Disney paper on geomapping, do you have any ideas on how they do it? I guess that you don't want to page in full models (as you either need a very l…

Seems like it took them a few minutes per frame to render TS1 in 2011 [1], not sure if that's with the higher resolution. [1] https://www.quora.com/How-much-faster-would-it-be-to-r…

They gave Yelp two options: either disable crawling in robots.txt, which means that Yelp won't show up in Google's results at all, or accept that Google will copy Yelp reviews with…

I wonder how they got that number. If getting Android notifications counts as 'using Facebook' then I'm one of those one billion.

The same can be said about Windows, yet both the European Union and the United States accused Microsoft of abusing their monopoly by bundling Internet Explorer with Windows. This a…

Google has a search engine monopoly (at least in Europe), this gives them the obligation not to abuse this. If they're using their monopoly to promote other services (such as when …

I think this is aimed at middle/high school students. It probably can be interesting for adults, but I'd really recommend picking up a book such as Fundamentals of Computer Graphic…

Yeah it was a great learning tool. pbrt is a good learning tool, but sadly it already implements most of the basics. Courses at Cornell and ETH Zürich used a small rendering framew…

I guess I didn't fully understand your post then, I thought you meant that the Reyes algorithm is an "inferior estimation" and that it might be beneficial to add it to a renderer, …

The CG by UC Berkeley on EdX is a great starting point. One of the exercises involves building a simple ray tracer. A slightly more advanced source on ray tracing is http://www.scr…

The REYES algorithm is an algorithm that can very quickly produce batches of shading points (with the required information to shade them such as the viewing direction). It's not re…

It's a bit unfair to compare the speed of Mitsuba with the speed of Renderman. Mitsuba only has a simple KD-Tree (although highly optimized), while RenderMan most likely has a stat…

Mitsuba lacks a lot of features that are necessary for production: there is no proper support for hair (Mitsuba only has a simple Kajiya-Kay shader and no specialized acceleration …

ssize_t is not a part of the C++ standard, sadly.

Most courses offer just the syllabus without any slides or notes on the ACM digital library. There were many other great courses, but most sadly haven't posted their slides and not…

Ask a random person if 1 and 0.999999... are the same number and most people will tell you they aren't the same number. Yet: 1 = 3 * (1/3) = 3 * 0.33333... = 0.99999... (they're al…

I completely agree with you that the information in that paper is excellent and I think it's amazing that Disney is so willing to share so much information about their renderer, ev…

Photon Mapping might be biased, but it's extremely easy to make it consistent by using the method outlined by Knaus and Zwicker [1]. Using that method photon mapping will converge …

This web page is from this month, not 2013. They published a paper on the architecture of Hyperion in 2013, but that never received a lot of attention as it appeared out of the blu…
