It looks really really good! I'm curious to see scenes with more geometric detail.

Interesting! The choice of where to AA is similar to "Discontinuity Edge Overdraw" by Sander et al: http://research.microsoft.com/en-us/um/people/hoppe/ But the way you deal with it is very different.

I'm sure I remember a paper somewhere that generated a screen-space buffer of the specific places where the "smudging" needed to be done, rather than doing each line separately. So much like the "future work" you suggested of a single render of the scene, rendering pixels to one buffer, edges to another, then the smudging pass is a single pass over the whole screen. Of course I can't remember where I saw it now - my brain is old.

Why do you say you're "copying" the first pass to a texture? It's not AA, so you should just be able to render directly to the texture, no?

Looks great! Got a higher res image to look at?

Are you using a depth-buffer for this effect?

I don't know why, but I've bunched your site together with Maddox's (maddox.xmission.com). Every few months I'll be reminded of one and immediately think of the other. That's basically how I've been able to keep up with your posts over the years.

Now that you're on Twitter, I'll be able to check up on you more often. I hope you'll be making posts more frequently.

Well that's all I have to say. Have a good one,

sqrt[-1]: Cool stuff. I definitively have to get my hands dirty in WebGL soon.

Seven: I tried poking around a little with that, but didn't note any gains.

And those smilies should be double-quote and close bracket... " ), not "

Right, I should have seen that was a power of two.

One other trick that I think you haven't used yet: splitting up your initialised data segment. Using #pragma data_seg directives, put every initialised global variable in its own datasegment, like this:

#pragma data_seg(".pfd"
static PIXELFORMATDESCRIPTOR pfd=...

#pragma data_seg(".coords"
static const float g_Coords[] = ...

Then, use Crinkler /ORDERTRIES command to let it try a few thousands(*) ways to order the data segments, and pick the most compressible one.

*May be overkill, depending in how much datasegments you create.

It took longer than expected, but I did manage to squeeze a port of this to WebGL in 1K (using some nasty hacks that may break in future browsers)

Tested in the Chrome build 10.
