A demo of Brigade 3 real-time path tracing at 720p controlled with an Xbox controller. Depth of field, field of view, reflections and shadows can be altered live.
Why Hacker News points people here: Cited as an early proof that real-time path tracing was feasible, years before it reached mainstream games.
“I wish nvidia or ATI would hire him.”
Near real-time GPU path tracing demo.
Why doesn't GPU hardware do native path tracing now? People (well at least 1 person) is/are using general purpose GPUs to do path tracing at almost real time. If they created GPUs with cores specifically for path tracing then we could have real time path tracing as soon as that was engineered. Whoever made this brigade 3 thing, I wish nvidia or ATI would hire him. this video
“I believe that real time ray tracing is going to be a thing within a few years”
Example of real-time ray tracing expected within a few years.
My favorite things right now which I am happy to recommend are ToffeeScript link with Node.js and Nimrod link . I also think LiveScript is awesome. AngularJS is great. Web Components are better I think though. Docker has redefined devops in my opinion link GLSL is very cool and something you can even experiment with in your browser using Three.js etc. I believe that real time ray tracing is going to be a thing within a few years this video link CoreOS looks very interesting. WebRTC is a technology that could almost make an industry irrelevant. link Understanding APIs around bitcoin and cryptocurrency in general seems important. I believe that the internet is eventually going to be switching away from normal named server structures to a content-oriented architecture. link There are a lot of ways this category of architecture is actually currently being deployed behind the scenes, for example CDNs or bittorrent. I believe that we are going to start using that type of system more and more and eventually we will lose things like the HTTP layer. This may be combined with some of the technologies related to cryptocurrency. For an example of why we are moving to named data networking, take a look at well.. just about any web application that wants to scale. For example the npm registry. Also consider the issues around privacy with Facebook and the NSA, and the ability for governments to censor or take down web sites or domains. So any technologies that facilitate things lik
“Apparently requires 2 Titan's to render.”
Real-time path tracing demo needing two Titan GPUs.
this video Apparently requires 2 Titan's to render. I wonder what you'd be able to pull off if money was no object
“Take a look at this video from 2013”
Earlier real-time path tracing demo with more detailed geometry.
It could look way better with more detailed geometry and proper materials. Most of those textures have baked-in lightning and lack normal maps and proper materials, which take away a lot of the effect. Take a look at this video from 2013: this video
