Reflect - Powered by Brigade2

EDIT: Game now available for download: http://igad.nhtv.nl/~bikker .

Reflect is a game created by students of the IGAD program, a game development course of the NHTV University of Applied Sciences in Breda, The Netherlands. The game uses the Brigade path tracer for rendering. Path tracing is a process that constructs a large number of paths between the camera and light sources (typically via scene surfaces) to estimate the color of each pixel. This is a stochastic process, which causes the noise in the images. Although more samples would reduce the noise, path tracing is rather compute-intensive. Brigade runs on one or more GPUs to provide sufficient processing power.

The scenes in the game show some typical characteristics of path traced rendering. Obviously there is the noise, but this is more severe in poorly lit rooms, and rooms with complex glass materials.

"I am a Christian" - really? how very professional to describe personal beliefs on a website about technical projects... (in case people wonder what i'm talking about - it's on the author's website)

[jaccobikker]

@notthere83 : Funny that you pick that, and not my family, which is also rather 'irrelevant' to the products on the page. :) Anyway, something as fundamental as my belief affects everything, and it drives me, and therefore it is on my webpage.

[notthere83]

@jaccobikker unless you do an interview and they ask you, i think it is appropriate to assume that nobody reading about technical endeavors cares what drives you.

i picked christianity because valuing your family is pretty much philosophically neutral, at least as seen from a global cultural perspective. any given belief is not. which is why a reference to it out of the blue is more irritating and less excusable than talking about your family.

[jaccobikker]

@notthere83 : I don't see why Christianity and my drive would irritate you. But I think we need to continue this discussion elsewhere: it's definitely off-topic here. Feel free to e-mail me, my address is on the website.

@notthere83 You mention of family being more excusable than religion, yet both these have no link, direct or indirect to path tracing. These, along with sports, interests, politics, future events, past events are as excusable as each other from an objective point of view. If you include them, they add nothing. If you include them they take nothing away. The world is full of people with 'perfect' CVs, but less than perfect people. It's the clever person that knows what to look for.

[antzrhere]

@notthere83 I didn't think I had to give an exhaustive list of items that fall under the catagory of personal, but it's fair to say there is no discernable difference between a person's interest in athletics, mountaineering, biology or religion when it comes to path tracing graphics? I understand your point that it has little to do with his work, yet in a reverse situation, you are putting more emphesis on his personal side (vs. technical achievement) than he ever intended to!

[antzrhere]

@sblawr Like it or not, even if current graphics techniques continue the way they do with rasterization, they will have to patch over with some of the general techniques applied here to make them believable. And some already do, like CryEngine 3 to give a very rough approximation of GI (albeit over-simplified)

[notthere83]

@antzrhere indeed. but last time i checked, personal beliefs are neither recreational activities, nor technical interests.

[antzrhere]

@notthere83 To illustrate, some people advise on CVs to put a line or two about your personal interests such as recreational activities and technical interests. Whether or not depends on what field you are applying for. Certainly in academia this is true. These are acceptable but are in essence non-objective and non-technical. However, to unintentionally judge that persons professionalism by these would comments (both good and bad) would be by definition unprofessional.

[antzrhere]

@notthere83 Whether or not his views are "professional",relevant or out of place,what has been disproportionately highlighted is your personal comments, not his. His programming work speaks first & foremost and is an objective gauge of his professionalism..THEN personal aspects can follow. There is a difference between unprofessional, and non-professional, the later while possibly irrelevant has no contribution to the final outcome, whereas you have given it added weight in a negative sense.

[sblawr]

I came to check out this vid from the tantalizing reddit title "Catch a glimpse of the future of 3D graphics rendering for games" and was greeted with pure garbage. What a joke!

[notthere83]

@eikons funny... in my last reply, i wanted to say the same about you. but i chose to not resort to that... oh well.

[eikons]

@notthere83 Except that website is something he made to tell people about his projects, his CV and a little about himself. There is no reason why he should restrict his website to one topic, even if it is the overshadowing one. Youtube is a public channel where you decided to take a bit you found on his website and point out how it's unprofessional, in the commentary section that is actually meant to discuss the video.

Say what you like, I think you're a hypocrite.

[notthere83]

@eikons yes he can. in fact, he is even free to delete this whole moronic discussion.

and i am free to point out that i think that it makes him look unprofessional and thus feel that it is unwise. and this video has just as much to do with it as his website. same topic.
