time to compare the state of real-time scanline game graphics to povray's
output. :)

here's an old povray favorite:

here's a real-time shot from today's console blockbuster Uncharted 4:

real-time soft shadows, real-time GI ("radiosity"), plenty of particles,
volumetric smoke, weatcher effects, nice physics-based materials, etc.  Each
frame rendering at about 1/30 of a second.

love it, HOF-level :)

Hmm, I don't know about that.

I'm not sure exactly what algorithm these game engines are using. (I bet 
Warp would know...) But I often notice that as the camera moves, certain 
objects leave faint "trails" behind them. It's as if the lighting 
approximation is doing some sort of iterative improvement, one iteration 
per frame. So the lighting converges to the correct values, but only for 
stationary images.

That's not quite "real-time". Close, though...

sure, squinting your eyes hard enough, you can pickup small issues and failures
here and there

but as the end result is pretty breathtaking and you're in the middle of the
action, you don't notice them.  Suspension of disbelief as goes the saying...

"Uncharted" and yet there's already people there shooting each other.

off the charts ;)

this one:

reminded me this:

mind that the game pictures were taken with the photomode (pauses the game and
allows free camera angles) and has (realtime) DOF applied and character
invisible

I hate how DOF is applied in games. Something about it makes it look
totally unrealistic. Don't know if that's due to some subtle artifact of
the fakery behind it, or just that it is totally exaggerated.

The latter I guess.

I haven't seen an example of this. (Most games just don't have a DoF 
effect at all.) But presumably those that do, are simply faking it by 
applying a Gaussian blur to objects a certain distance away. Which isn't 
how real DoF works...

Somewhat tangentially related, but still very interesting:

I applying DOF myself in this shot, pausing the action and freely controlling
the camera:

http://fbcdn-sphotos-b-a.akamaihd.net/hphotos-ak-xtf1/t31.0-8/fr/cp0/e15/q65/13268250_1728775957406878_2698799888800070
23_o.jpg


it's the usual zbuffer DOF from scanline, doesn't even employ bokeh but it's
enough for gameplay, like when aiming the gun.  I passed by this character and
saw the beautiful lighting all over her and had to take a pic...
