Good to see most of you still here.

I have been thinking of doing a new method of ray tracing fast enough to be real time, but I have not got around to doing any code yet. I might give it a go in a week or two and post the results. (it's just an idea in my head right now.)
Real-time ray tracing really isn't much of a problem these days. Its just that it costs more at barely any winnings compared to rasterization, so nobody uses it. Things get more interesting if you do path-tracing because you get unbiased global illumination. However, this is still too slow for serious real-time stuff. Can be done though, see Brigade.
That engine is stunning. Unfortunately the amount of noise between renderings is probaby too high for a mainstream game.

They should developed a predictive algorithm to the prerender the next frame, and reuse traced paths for linear movement. (until enough new paths are formed to render without noise.)
As far as I know that's what they already do.

If you want global illumination at interactive frame rates, path tracing is going to be the wrong approach for many years to come. Kindof hacky things like voxel cone tracing are a better option. They scale well in the sense that you can get worse quality at shorter runtime without getting completely noisy results. This is important because the human visual system is not sensitive to mistakes in indirect illumination.

Also, I think I just found a fancy new formula that could make Kinect One awesome.

For your perception no.

Both renderers are pathtracers, so that's why the results look sortof similar. They are just optimized for different use cases.

So, today I finally got around to tinkering with my Raspberry Pi, I must say, it works way better than it did when I first had it, not sure if it is because im using a "custom" version of the wheezy distro or if they fixed some of the early issues. I can even browse the web without too much headaches, (though, this browser has no javascript :( )

Included are two screenshots I took, it feels as if I am using a pentium 2 again :) not too fast, but fast enough to work with. (Not to forget the nostalgia which comes with the low performance). They are in this resolution since I bought a 11 year old screen to accompany the pi on my trip to nostalgialand.

Ah yes, good old 4:3 aspect ratio.

Why do these screenshots have the exact native resolution of my desktop monitor :think: .

I considered getting myself an Ultra HD monitor, but I'm hesitant due to the low refresh rates and because I consider aspect ratio 16:9 inconvenient for programming.

dude after using several wide screen monitors I can safely say that you are missing out.

But yeah rei all hyped up from loading webpages on pi with good speed.

You should check out the latest build of wheezy for pi.
And yeah they never had any drivers to start with when the pi was released...
Just like most android phones without source everything has to be totally ported or written from scratch.
1. so it's a slow process
2. that requires a large fan base
3. with competent hardware coders

like for example the pi using proper hardware codec's now for video, recent additions to the gpu source code.
In due time every transistor will do it's intended job and slow software based rendering ect.. is replaced.
It's always like this with dev boards... "needs time, and a big community" <_<

Widescreen for programming is actually quite nice, but I use two windows on them at once, like the IDE at one side, and a web browser at the other. You could also tilt your widescreen 90 degrees. so you have a long screen.

But yeah I actually use two widescreen monitors for programming, for me, it works like a charm.

Lol, apple. That must have cost a small fortune.
very nice though, it looks like you need a better keyboard and mouse for ergonomy's sake.

Furthermore I upped the pi's nostalgic value, not sure if that is a good thing..

Well, it's not that I haven't programmed on 16:9 screens yet, but I always found one half of my monitor ending up useless. I don't want something else on the right half because I find it distracting.

BTW: My monitor at work is huge.

I have two sets of 24 inch 16:9 monitors with pivots, side by side. The one on the left is rotated vertically for coding. The other one is used for everything else. Alternatively you can have two 16:9 monitors pivoted vertically side by side.

Hehe, I use my 40" tv as a monitor for my PC, it's quality is actually better than my normal pc monitors, though I have to tilt my head if I want to look from one corner of the screen to the other.

Eizo makes some good stuff, that monitor must have also cost a small fortune :O (When looking at it from a student point of view). My TV is only 1080p so I can basically count the pixels (if I look closely I can see the space between the pixels even), but I dont really mind, we have anti aliasing nowadays anyway. Though I wonder if I am not seriously lowering my TV's lifespan by keeping it on during the most part of the day (when I have holidays at least).

My TV
I bought it for €399.- a bit more than a year ago, do note I don't program on this, just for entertainment, games, movies and browsing the net.
