It's pretty cute! Did you figure out a solution to your lights question, or did you just use deferred rendering / crank it up to like 16 pixel lights?

I just went with deferred rendering. Forward rendering with even 10 pixel lights in that scene completely trashed performance.

It's probably obvious, but is this often optimized by rendering the individual blades within a certain FOV and distance, and then just fading that to a texture or bump mapped texture? I'm betting on the new Zelda doing that.

From what I've seen, yeah, you start at the individual blades, and fade out to cross sections, and finally horizontal slabs.

Here's a great resource on it: http://www.kevinboulanger.net/grass.html

You've got it. I have a few images to cross-post from my project.log thread.

I'm making some good progress on designing a BBB cape board to interface directly with SNES/NES gamepads to turn the BBB into a proper retro gaming console:

I made some renders, too!

This cape board will provide an interface between the real-time unit GPIOs and the gamepads, a battery-backed real-time clock, and an EEPROM to report the cape to the BBB kernel capemgr. Because the gamepads use a 5 volt logic level and the BBB GPIOs use 3.3 volts, I have four BSS138 transistors on the cape to perform the line-level conversion.

But i know what you're thinking.. those explosions don't look very impressive. So lets see what happens when they can use asteroids as weapons.

Thats more like it.

Still to do:
More super weapons.
Better planet deformation/cratering.
Decals/ texture changes.
Whatever else needs doing.

GI_Clutch: Aug 22, 2000; by Fluffdaddy; Dinosaur Gum

Our product delivery team is in the early stages of rewriting our flagship product as a web application and is implementing log4net. I'm on the services side of the organization (implementing our software, other software, etc. for our customers), so my code is usually limited to things such as flat file preprocessors, web services, or other code to fill in the gaps. Coding is not a job requirement, but a nice thing to have. Things are slow at the end of the year, so I decided to take on a pet project.

One of the pieces of software we resell has some nice tools for viewing everything that goes on in real time. I figured it would be nice to have something similar for our software. So, I put something together over the past few days that does just that. It listens on a specified port and logs anything coming in from a UdpAppender from the application.

It's not as exciting as many of the other things posted in this thread, but it was a decent learning experience for myself. I learned how to create custom configuration sections, so the columns and their attributes (is it filterable, should it create a dropdown of logged values to select in the filter, etc.) can be configured to your liking (just make sure your patternlayout matches). If you save your log results, it saves the column configuration along with the rows so that it can be reopened on another machine with the same columns and filtering options intact (versus blowing up if they don't match the other machine's app.config).

Here's my Advance Wars-inspired game that's going to come in multiple versions (graphical version coming later). The game is already modifiable through a tool - in fact, everything that you see has been loaded from files.
I'm currently lacking some minor features (repairs, ground-air combat, victory/failure states and cover), as well as some major features (commanders) before I have something that can "emulate" Advance Wars entirely. Obviously, my goal doesn't end there. I want multi-player over the Internet.

Edit:
Oh, and this runs on Windows and Linux. Language is C++, the library used to "render" everything is pdcurses (Windows)/ncurses (Linux).

Internet Janitor: May 17, 2008; "That isn't the appropriate trash receptacle."

Lately I've been playing around with the K programming language, which is in the APL family but only uses normal ASCII characters. It doesn't have very many interesting IO facilities built in, but it occurred to me that stdout is all I need to recreate a classic graphics programming hack.

The source:

code:

rotate: { cx:2.3+_cos y[0]; cy: _sin y[0]; / [(A;B);(theta;phi)]
          cp:    _cos y[1]; sp: _sin y[1];
          ca:    _cos x[0]; sa: _sin x[0];
          cb:    _cos x[1]; sb: _sin x[1];
          xp: (cx*((cb*cp)+(sa*sb*sp)))-cy*ca*sb;
          yp: (cx*((sb*cp)-(sa*cb*sp)))+cy*ca*cb;
          zp: %5+(ca*cx*sp)+cy*sa;
          (_40-30*xp*zp;_20-20*yp*zp;zp) };

render: {{.[`b;(y;x);|;z]}.'+rotate[x;grid]};
grid:   +,/t,/:\:t:0.8*!80;
disp:   {`0:"\33[H",,/{x,"\n"}'" .,-~:;=!*#$@"[_15*x]};
main:   {1}{b::40 80#0.0; render x; disp b; .07 .03+x}/.0 .0;

I've simplified the original by removing the luminance calculations and simply rendering the z-buffer. This version is fairly slow in Kona, so I also decreased the density of the plot, leaving visible seams. Still tinkering with it.

Recently (like four months ago) a Kos thread on Hacker News prompted me to look into it, man is that language and its proponents weird. I have seen people say that they want it to be terse and dense because that makes it better somehow, this looks like I might understand it if I try.

There was also a lot of talk that Koan is not at all a good version of K and that people should use the version available with kdb+ at https://kx.com.

minidracula posted:

disp is definitely the ugliest and most cryptic looking routine there but most of that is because "\33[H" is an ANSI terminal escape code and " .,-~:;=!*#$@" is a grayscale character lookup table.
Idiomatic K style is quite unusual but of the APL family languages I have tried I find it the most pleasing to work with. There is a paper discussing K style which I found interesting, and at least somewhat convincing.

minidracula posted:

Kona targets K3 but the devs are open to implementing features from K4 and K5. It's alright. Nearly every time I've written a significant program with it I've found bugs or inconsistencies but the devs are fairly responsive to bug reports. It might be a better idea to play with KDB+, especially if performance is important, but Kx is really only supporting Q, a syntactic sugar layer which builds on essentially undocumented K underpinnings. The situation isn't too great for beginners from any angle. For my part I'm trying to do nice writeups for the programs I write.

kOS was what made me interested in K as well. It's a bit frustrating that K5, which is incompatible with prior versions of K in a number of ways, is teased at on the kparc site but unavailable to the public (on the basis that it's still heavily in flux). I've written my own non-canonical K5 interpreter based on the information I could glean. It's written in JavaScript so I expect it to be ponderously slow compared to the real thing but it's pretty easy to hack up if you just want to experiment with the language. I think I have a good portion of the language featureset down now (no doubt with many lurking bugs and mistakes), and having gained a better understanding of the problem space I see many ways to simplify and cut down.

Boring web developer time!

From ComBoards, my community-based job board startup concept. Quite spartan, but it's meant to be embedded and I just deployed it today after some light work over the holidays.

I'm most fond of the semi-private implementation. You can only get to a board via the keyed link:

http://comboards.com/k/h9px3QCGIw

Once you've visited that, it's saved in your session, along with the other communities you've accessed. If you register and then visit the link, it will be linked to your user.

e: aaaaand I realized that it was busted in that, if you visited while signed out, it forced you to sign in. very embarrassing after I even bragged on that feature.

Third iteration of the music events / soundboard tool. I've been working with an audio guy who has been using that to design event based for my space game. The idea is that you define states that are used in the game for the music and then define the tracks that belong to the states and effects. Once effect is given to the handler the lib automatically applies the effects.

He has been experimenting with the music and different ideas for effects and I've implemented his effects. The same implementation as in the tool is also used in the game. Unfortunately, the only effects that I can get reliably working cross platform are those manipulating volume such as fade in/out.

THE PLATFORM MASTER: Jun 3, 2008

For a while I've been reverse engineering the Source engine networking for Dota 2 aimlessly. So far I've completely implemented connecting to a game as a player and spectating other player's games. My current goal is to make my own bot for Dota 2, which the video below shows. Right now it connects to the game as a player, immediately selects Nature's Prophet, and then immediately makes a move towards the fountain. This video is filmed using my Steam account so we can watch what the bot does, but there's no need for me to be running Steam or Dota 2 for the bot to work. This is all super exciting, because it means I finally speak to the game coordinator (including VAC) and the game server fluently, and all that's left is actual bot logic. This is all a C# program built on top of SteamKit. I would love to chat with someone from Valve about it!

Yeah maybe, I'm just doing it for fun so I'd be bummed if they got angry. There's some good uses for it, for example you could automate amateur league hosting and statistics collection. Another idea someone had is making a platform for people to write bots on and make them compete like that StarCraft competition. The network parsing is useful for spectator analysis of live games. At the same time I love playing Valve games and realize this could be undesirable so I have absolutely no plans to release it. Dota 2 is also moving to Source 2 soon which will break a lot of this too.
