Using Rectified Linear Units seems to be working VERY well. I'm glad I ended up implementing them.

This is from waay back but pretty cool stuff. Came across it since I'm now trying to build a RBM from scratch so this is going to be a fun time figuring out all the gaps I have in ML knowledge :v:

This is more stuff I worked on in July but our procedural wood got released this weekend! :toot:

I didn't contribute much to the overall material model beyond a few very minor tweaks, but I did code the noise functions, the Marschner BRDF sampler, material shader and so on for the path tracer implementation. My model and material choices are ... programmer-y, largely because I was working with 5 alpha material presets, some random .obj:s I had on my drive and our testing framework. I could probably do better with the actual release even with my anemic design skills but that would be cheating.

Turns out making everything appear carved out of single solid blocks of wood makes it look like you're post some artisanal and particularly hipster sort of apocalypse. Also, I should use less dof.

Nah, there's totally a bunch of junk just floating in midair for that shot. Also, the exhaust isn't connected and is intersecting the drive band thing. It's a random model from some test suite.

It pauses every now and then because the CPU is being driven by setTimeout, not the Web Audio API. And it's also faster than you remember because I'm feeding it 32kHz audio and your browser likes 44.1kHz or 48kHz instead.

Please use requestAnimationFrame instead of setTimeout so it loses focus gracefully

I have to confess that Internet Janitor's continued interest in K/Q/Kona/oK and posting about it is one of the things that's keeping me coming back to J, K/Q, and now actual APL on a more consistent cadence than I previously kept (maybe once a year or longer between fiddles). Thanks Internet Janitor!

MrMoo: Sep 14, 2000

Firefox and Chrome have quite an odd event loop which can also process tasks, delayed tasks, and idle tasks. The DevTools interface uses this task feature to communicate between threads and an internal HTTP server, I have cloned this functionality in a very simple market data land app. There are two completely independent threads, one consuming market data (AAPL, MSFT) and storing a cached copy, and one providing copies of a CoW snapshot of the cached copy. I don't want both threads to stall when querying instrumentation and I don't want to be completely mental and have a separate HTTP server for each thread, just the provider. So the HTTP frontend queries over a web socket for provider and consumer thread information, the provider thread can reply immediately, the consumer thread request is enqueued as an asynchronous task. When the consumer thread has finished processing incoming data it executes any tasks, one such is to query the thread instrumentation (which thus does not requiring any locking or synchronization), serializes into JSON and punts back a new task to the provider thread as another asynchronous task. The provider thread then wakes up reads the JSON response and forwards over the web socket.

C++ code:

  // The anatomy of a typical run loop:
  //
  //   for (;;) {
  //     bool did_work = DoInternalWork();
  //     if (should_quit_)
  //       break;
  //
  //     did_work |= delegate_->DoWork();
  //     if (should_quit_)
  //       break;
  //
  //     TimeTicks next_time;
  //     did_work |= delegate_->DoDelayedWork(&next_time);
  //     if (should_quit_)
  //       break;
  //
  //     if (did_work)
  //       continue;
  //
  //     did_work = delegate_->DoIdleWork();
  //     if (should_quit_)
  //       break;
  //
  //     if (did_work)
  //       continue;
  //
  //     WaitForWork();
  //   }

Blue Footed Booby: Oct 4, 2006; got those happy feet

Dicking around with my terrain generator. I got rivers working! Kinda...

It picks a random point, and assigns it a flow value. A pixel with flow value 3 will flow to the 3 lowest adjacent pixels. Pixels with flow 1 never exhaust and just flow until they have nowhere to flow to. It does this for however many water sources are specified on the setup tab.

Next step is to implement pooling when a river hits a low point with no lower neighbor pixels. Then I can figure out outflow from lakes and the rivers may eventually hit the goddamn ocean at a rate higher than 1 in 8. The realistic/logical way to accomplish that goal is to somehow model erosion such that rivers carve their own channels to the sea, but pfffft, gently caress that.

I'm pretty pleased with this shitheap considering how little actual design went into it.

Rahu: Feb 14, 2009; let me just check my figures real quick here; Grimey Drawer

Rahu posted:

I am not very far into this yet, but I'm working on a Cycles renderer plugin for 3ds max.

So far I can get the camera transform (almost) set up right and render all the meshes in the scene at their correct transforms and object color (but not any real materials). I also have progressive rendering working because cycles gave that to me for basically no work.

Up next is the long slog of mapping max materials to cycles shaders.

Small update on the progress I've made here since october.

I've rewritten basically everything as I didn't have a good handle on the max API at first. Now that I do I've been able to reogranize all my bits and bobs in a better way.

I also gave up on the effort to map max materials because that was really just a mess. I have a bad approximation of the standard material in and I'm working on building support for the native cycles material types in the max node editor.

Recently, I added the emissive material as well as support for most of Max's native texture types like bitmaps, which together allowed me to produce this art!

As far as generating the base heightmap, I have no references and no plan. I just do stuff and sometimes it works. The implementations of perlin and simplex noise presumably came from the internet at some point in the past four or so years. I found them on an old hard drive and started this project on a whim.

The terrain in that screenshot is 5 layer of simplex noise, each with twice the frequency and half the amplitude of the previous, and each with a random seed. I assigned colors to arbitrary height ranges--picking colors to make it look terrainy--but it's still basically just a heightmap.

I stumbled on this page about erosion modeling algorithms the other day but haven't tried any of them yet. They seem surprisingly simple.

Thanks for the helpful criticism. I took the time this weekend to create a version of the site that is almost entirely rendered server-side, so while there might be a couple of places where the flash of un-angularized content still comes up, I think I've mostly alleviated those issues. Now comes just using the site and seeing what is broken with any regularity.

That's the nature of ads, I suppose, but I made the containing div have a white background so they don't peek out from the bottom.

Oh and I made the repo public on Github, so anybody can submit issues there and i'll try to address them. I refactored a huge chunk of the app and got rid of a bunch of routes, so if there's something I didn't test for, please feel free to let me know.
