Well, I didn't finish anything yet, but I'll share three mesh-related mysterious screenshots of work in progress (hopefully I finish one of these over the long weekend):

Basement

I'll at least say what this one is: I've been experimenting with photogrammetry, which is remarkable technology that reconstructs a scene from photographs. In this case, I took about 750 photos of my basement, and just from those photos (and several hours of CPU/GPU time), software is able to reconstruct where the camera was located for each photo, then use the alignment of those cameras to infer the geometry of the scene as well as textures. It's pretty amazing to me that this works (I mean, obviously our brains can do this, so it's clearly possible, it's just impressive) and it's actually pretty practical for capturing a scene. In this case you're seeing a corner that I didn't photograph much, and haven't done much cleanup on. I've been working on my blender skills in an attempt to make a decently complete and clean model that can be experienced in VR, for those times that I want to go down to my basement but don't want to actually descend any stairs.

Now, two mysterious ones:

New applications of paint (31 May 2017 at 17:43)

Ha! This month I remembered to post on time. Nothing that interesting to share yet, but I continue to make progress on my game project (getting over some of the annoying and frustrating hurdles like making the somewhat unique physics work well), and had a couple new weird applications of computers ideas that I played around with and that might become something but who knows. I'm also the kind of person now who spends a long weekend organizing his basement. For example, there was this gross old rusty metal cabinet down there,

The cabinet was fixed by closing it

just covered in this disease-like rust, and I spent rather a long time sanding it down and repainting it in a tastefully selected tri-tone and then painting it again when the rust disease just poked grossly through the paint right away, like four times. And then I realized that the shelves are not actually good for storing the kind of hoard of miscellaneous electronics bits and other weird parts that I might use for something someday, so I started making some unreasonably nice wood boxes to put in the shelves, and that's what I was up to yesterday evening. And this is in like a spider-webby moist corner of my basement. Meanwhile I have like a pile of clothes in a bag on the floor of my bedroom that I still haven't put away since moving in. Difficult-to-justify prioritization, evidence of eccentricity, and such.

I played a couple of video games recently, and one that I really liked was called Environmental Station Alpha. It is mostly a straightforward Metroid-style game (with even some blatant inspiration/homages), but for me it had a nice difficulty curve and just the right balance of abusable bugs, as well as some great music and weird secrets. (The depth of different endings and things you can do if you really get into the game is quite impressive.) That was one of my favorites in recent memory, and if anybody has recommendations in that vein I'd be delighted to hear 'em. I didn't write a review of this one yet, but I do write a fair number of reviews on Steam (here's my reviews page).

Tonight I am going to the Penguins in the Stanley Cup Finals! :) Let's go Pittsburgh!

Again I have failed at posting on time. This one was backdated from May 1 with no excuse! At least it's not so common that I've written a way to do this without manually editing timestamps in the database...

I took a short break after last month's too-much-work SIGBOVIK project, and then eventually decided to get back into working on a game project that I started a few years ago but abandoned for no good reason. I'm definitely deep back into it, though I struggled all weekend writing and re-writing some of the core physics stuff, and it's been frustratingly slow. The whole point of doing a game project is to do something where I know how to do it and can spend most of the effort making content instead of beating my head against the wall! But I guess pretty much all programming projects that interest me these days have some head-beating. Hopefully I will figure that part out before I lose momentum, and will have something to share soon. :)

SIGBOVIK 2017: ABC (31 Mar 2017 at 12:34)

Hello my bloggies! I back-dated this post because even though I was all set up to post about my SIGBOVIK accomplishments, which this time conveniently occurred in the month of March, I then celebrated SIGBOVIK so thoroughly as to go to bed without actually posting here.

This year's invention is a strange artifact; if you want to experience it with fewest spoilers and have some time, then check out the paper version. I also put together a youtube video, since I like doing that:

SIGBOVIK 2017: Compiling C to printable x86, to make an executable research paper, by tom7

Click for nerd-talkin'

Despite the possibly misleading thumbnail, the video is mostly live-action, as I it after a popular YouTube series called Numberphile. The project doesn't lend itself too well to video, so my feelings won't be hurt if you don't sit through this one. :) I did my best to make the ideas and puzzles fun for people that don't have deep knowledge of this stuff but are interested.

SIGBOVIK was also live-streamed, so for the first time we have a mediocre recording of all the talks if you want to tune in after the fact too. My talk's at 1:22:00, and it's more bite-sized than the above.

Also, I must say: The conference this year was excellent, perhaps the best ever. The conference hall was packed; the overall quality of work was very high; the proceedings is thick with really interesting stuff (interspersed with the requisite juvenilia), and the talks were well-prepared and didn't drag on, thanks partly to the new timer system. It's pretty crazy how this conference has a life of its own now; almost nobody from the original group is organizing or even writing papers for it. We may even be getting to the point where we have to be selective about what we print..???

SIGBOVIK cometh (28 Feb 2017 at 20:53)

Oh goodness, months since anything to share. I really am working on this SIGBOVIK project for the impending deadline (and if you have anything you'd like to contribute, now is the time to get serious), even taking some vacation days later this week to finish. It's in that awkward state where I've put months of work into it, but I'm running out of time and might not get everything I dreamed of done, but I'm far enough along that I really ought to finish it for this conference. But this is what deadlines are so good at.
