At first I thought you were just doing voxel tests, but now it sounds like you're actually trying to render a whole scene as voxels, so does that mean you're trying to make it playable? The metadata has to be hand-crafted, so it is quite labor-intensive to get a game running using what I'm setting up. Without hitting too many special cases, you could probably get most of the really early NES titles working with this voxel technique. From hendersa posted:Well, I guess there are six parts: Basically, it is an augmented reality version of SMB. It is too slow to render voxels for every pixel, so I reduce the rendering area to what is near Mario. Since so many of the pixels around him will be empty, I can probably render a larger area than what I have been rendering.  I've got metadata for around 25% of the tiles in SMB right now. The pipes look amazing. hendersa fucked around with this message at 17:57 on Dec 17, 2013 |

Voxelization of a 3D scene using this paper; http://www.seas.upenn.edu/~pcozzi/OpenGLInsights/OpenGLInsights-SparseVoxelization.pdf, in OpenGL; Currently rendering the voxels as GL_POINTS. The idea is that I inject lighting into these voxels to approximate global illumination with cone tracing (paper: http://maverick.inria.fr/Publications/2011/CNSGE11b/GIVoxels-pg2011-authors.pdf). We'll see how that goes.

Maybe make any black pixels adjacent to transparent part of the sprite transparent? But it is pretty cool as is. I need to get metadata working first in a way that does not perturb the existing graphics pipeline. Once the orthogonal voxel processing is working, I am going to try placing additional information in the metadata fields to override portions of the rendering pipeline, use multiple voxels per pixel, handle water/lava, and some other tricks. It's a (big) work in progress. I also just got some proofs back today from my publisher for the latest magazine article that I wrote:  I never expected the graphic artists to make an article on kernel data structures and processor pin multiplexing seem so... interesting. My last article on BeagleBone Black HDMI and audio is hitting the stands today in the newest issue of Raspberry Pi Geek magazine, too. It is always amazing to me to see these proofs because I'm sending the publisher a text document with special mark-up tags in it and a few diagrams drawn with xfig and LibreOffice Draw. It comes back looking like an actual magazine with all the clip art and layout work done really well. Never let it be said that the various projects that we talk about here are just worthless tinkering. I did my BeagleSNES project and that led to me writing and consulting and stuff! You never know what these hobby projects will turn into one day... Oh, and Lifehacker did a story on BeagleSNES a few days ago and I am still being totally bombarded with mail from DIYers who want to make SNESes for family members as Christmas presents.

I could see people implementing this in more common NES emulators and annotating lots more games. For outlined sprites, it might look better if you stretched an adjacent non-black pixel along the depth edge than the outline. But the pipe top would be better black, and that requires even more sprite annotations... It looks like there's some z-fighting in that render. Are you doing repeated floating point additions when generating vertex coordinates for each trixel? Multiplication might be more accurate. I hope you convinced them to go with less ridiculous capes clipart. Scaevolus fucked around with this message at 07:26 on Dec 18, 2013 |

I read this arcticle about mark & sweep garbage collector and since it looked easy I figured I'll implement a simple asm-like language that has a garbage collector. Here's a random array being sorted using quicksort. It allocates temporary arrays that must be then collected.

I started playing D&D 4e a few months ago and wow there is a serious lack of online tools. I mean, there's Roll20, but we actually want to play at a tabletop, and iPlay4e costs money. I just want to keep my character sheet in a digital format that I can back up, have easy access to spells, and have some offline capability. I also want it to be pretty dead simple and really just a digital character sheet. Still a lot of work to do, but it's shaping up into something usable. I have not written a single unit or end-to-end test and I don't even care right now. I'd like to add a feature to watch another users' HP or something. (as an excuse to play with SignalR more)  It's actually live at https://dragonputer.azurewebsites.net too, but the Facebook part is in sandbox mode so it's local saves only unless you're me.

Scaevolus posted:This is really cool and I'm looking forward to the final result. I could see people implementing this in more common NES emulators and annotating lots more games. I think that some creative use of metadata can reduce/remove the issues with those black outlines. I've actually been doing some work with expanding the metadata held for each pixel to handle some of these things. As for the artifacts, that is more from the capture process because I'm using Linux in a VM on a Windows 7 laptop with a fairly poor Intel GPU in it. It actually does not look at bad when I'm watching it live versus the Gooncam capture. Each voxel is translated into place from a reference matrix, so there isn't any sort of additive error that I am aware of. I don't have any say over the clipart. Turns out it is part of a theme that they use. There is a big, muscular superhero on one of the other pages, too.  <-- Reference (29 unique tiles) There are some interesting things going on here. First off, I expanded the metadata to allow for one to three voxels to be displayed on each pixel for the background. There are two reasons for this. The first is that I can now render background stuff both in front of and behind sprites at the same time. This will allow me to keep the posts on the bridge, and it gives me the added ability to make objects "hollow". An example of that is the opening of the pipes that you see here. I also use it on the Bullet Bill cannons. The second reason is that I found one particular tile is reused in three contexts. That tile is an 8x8 solid color square used for both the horizontal and vertical portions of the pipe (and probably something like lava or water, too). This means that I have to specify multiple depth maps for this tile. The spinning pipe segment here uses that tile in two different contexts, and it turns out to be OK with the new metadata. Keep in mind that I'm only specifying the metadata, a sample palette, and a small section of tilemap to tell the renderer how my test "level" is laid out. Everything else is pulled from the SMB ROM to render this. I have metadata for over 200 tiles, and will probably have metadata for the remainder of the background tiles calculated fairly soon.

This is something I'm pretty happy with, at least from a package/documentation/testing angle. I made and packaged (via Bower) a custom AngularJS directive* ( I'm calling a "depth chart" (a particular type of HTML table). https://github.com/robdennis/ng-depthchart and used by the Magic: The Gathering Deckbuilder I'm toying with: http://robdennis.github.io/lambic/ * if you're not someone with a lot of experience with Angular, it's a thing that will dynamically render HTML, usually given some sort of complex input.

I've been a bit busy over the holidays, but I did manage to pull together some of my voxel metadata work yesterday to see where I stand. I have metadata in place for all of the background tiles (256 of the 512 total tiles in the PPU), so I did some test renders of most of the big items. I put together a video of it here: https://www.youtube.com/watch?v=_AVj0ud9zP0 The new metadata format for multiple voxels per pixel is working really well. Also, I've been keeping an eye on the progress of the 3.12 kernel for the BeagleBone Black. There are still some issues in the port of the Capemgr subsystem from 3.8 to 3.12, but 3.12 has alpha SGX support in it (hardware accelerated OpenGL ES), so I'll try to move to that as soon as it stabilizes for all of my BBB/BBxM projects. I'd rather use GL for scaling, rather than the software scaling, plus it will allow me to support higher-resolution HDMI displays. The mails keep coming in from various people that have been tinkering with the BBB over the holiday break. Probably the most surprising was a mail from a team at the US Postal Service that wanted to use the BBB with Android to drive HDMI monitors at their facilities. There were a few different usps.gov addresses CC'd on the mail, so I guess it wasn't just one person idly wondering about their own pet project. I wonder if anything will come out of that...

I'm getting a lot less questions on it than I anticipated, which means that either people understood everything in the article perfectly and I did my job better than I thought I could, or they played with the pretty demos and thought the actual article was too hard to understand or tl;dr. So, let me ask you guys: did you understand the material? Or was everything perfect? Should I write less for the next article? Write more? Did I spend too much on basic stuff everybody already knows and then when we got to the complex stuff, "the bottom fell out" and you lost me? Any technical questions left after reading that?
