The Adventures of Bruto

Amber commented on a previous post, expressing interest in playing the game I mentioned there. Here is a link to download it:
You will need to have the Isis Game Engine installed in order to play. Unzip bruto.zip and double-click bruto.iss to launch it (if you didn't use the Isis installer, run bruto.iss with the 'ivmconsole' program).
You control the dragon and must protect your hometown from marauding invaders. Fly around using the I, J, K, and L keys. Spacebar breathes fire, and the F key sucks in air in order to shoot fireballs (if you don't like those controls, you can edit dragon.iss in notepad and change them). You win after defeating 20 ships, or you lose when your town and castle are destroyed.
If you don't want to download the game but still want to see it in action, here is a WMV video of me playing. Note that the video has no sound because the game has no sound. Here's a low-quality YouTube copy of the video:
Isis
A couple of people were curious about the game engine behind Osiris, so I have written up a little page about it:
There's not much on that page yet, but it has an introduction to IsisScript and a couple of sample games. There are also links to the installer as well as the source code if you are interested in checking it out.
Google stats
As I mentioned in a previous post, one of my goals for this web site was to be the #1 Google result for a search for my name. As of yesterday (June 26th 2006), this site had been around for little under a month and I had captured the #3 spot, even beating out the other Eric Faller who owns http://www.ericfaller.com/. The #1 and #2 spots were still being held by the GameDev club at the University of Colorado. Ironically, I created those pages while back in college and now I can't get rid of them (grr).
Yesterday Microsoft posted a Scoble video of my coworker Savraj and me explaining what we work on all day. Within one day, that page shot to the #1 spot on Google for a search for my name (#2 for Savraj). Less than 1 day for the #1 spot! I was very surprised. Unfortunately that page already seems to have been linked by a lot of other bloggers, so it will probably be very difficult for me to beat it any time soon.
The video isn't that bad, but unfortunately I had a very bad haircut when it was shot, and I and do a poor job of speaking clearly to the camera. I also manage to screw up one demo 4 times in a row, after I had just said something like "Oh yeah, I do this all the time"
. If you are interested in checking out my office and seeing what I do all day, check out the video. (Yes I realize that if I link to it too, that will only make it worse)

SD vs HD
Fortunately, my problems with the video quality of the DCT-3412 cable box ended up not being so bad, for the simple reason that all of the channels I receive seem to be digital, so they can all be recorded via Firewire (as long as they are not protected with DRM). Also, connecting the MCE via S-Video instead of the RF tuner increased the video quality for shows I can't record with Firewire.
Once that was all working, I did some tests to see how noticeable the difference between SD and HD really is. Here are some pictures:

Standard Definition
High Definition
Obviously the HD screenshot has been shrunk to SD, so they look about the same here (except that the HD shot is in 16:9). Click the HD thumbnail to see it in its full resolution (HD 1080i).
Here are the two shots scaled to the same size, for an easier comparison:

Standard Definition

High Definition
The last shot clearly shows HD's better picture quality, but ironically the newscaster actually looks a bit better and younger in the SD shot, since the blurriness of SD masks wrinkles and imperfections, while HD hides nothing. (I'm definitely not the first to note this irony)
Mac Mini Media Center
Last week I finally caved to peer pressure and got cable TV installed. Instead of actually watching any TV shows, I went right to work on getting the TV signal hooked up to my computer so that I could record and watch TV on it.
Unfortunately my computer is very loud and heats up my room whenever it's on, so I couldn't imagine leaving it on all the time in order to record TV shows. So I looked around for a small & quiet, yet still somewhat powerful computer. I decided to get one of the new Intel Mac Minis:

So far it has been pretty good. It has its pros:
- Small
- Quiet
- Intel Core Duo processor
- DVI & digital audio out
and cons:
- Weak integrated graphics
- No CD eject button
- Some of the hardware doesn't work under Windows
- No expansion capabilities (i.e. for a TV tuner)
Surprisingly, it was fairly easy to install Windows XP Media Center Edition 2005 on it. I only had a couple of problems:
- I had to burn my own install DVD since Apple's Boot Camp software only likes XP Home & Professional
- I hit the infamous and deceiving "Setup cannot find the EULA" error message, which was caused by the large hard drive getting formatted incorrectly by Mac OS X, so I had to re-partition it by hand
For the TV tuner I got a Hauppauge Win-TV-PVR-USB2-MCE:

I thought this would be a good tuner (even though it's USB), but unfortunately I was disappointed. The video quality is noticeably blurry when compared to component output from the cable box. I haven't figured out yet whether it is the fault of the RF encoder on the cable box or the USB tuner, but it could probably be either one (or both).
The tuner quality was not supposed to be a problem in either case, since I was planning to grab the raw digital video directly off of the cable box using Firewire and Tim Moore's set-top box controller software (recommended by my friend Mike). Unfortunately that plan didn't work out so well either, because Comcast gave me the new cheapo Motorola DCT-3412 STB, instead of the good DCT-6412, which included an MPEG2 encoder and could output any channel over Firewire:

So I can only record analogue channels using the blurry tuner, although digital (and HD) channels should work fine over Firewire, once the kinks are all worked out.
Ultimately it didn't work out as well as I had hoped, but it should still be OK since I can always record analogue shows on the Comcast box and watch them there. Here's a picture of the final 'Mac Mini Media Center':

Osiris
I've been asked a few times for a copy of Expedition: Osiris, an educational computer game I worked on while in college. Unfortunately some of the images of Egyptian artifacts that are in the game are copyrighted by the university, so the game cannot be distributed publicly. But, I did get permission to create a "public domain" version of the game, as long as all the artifact images were obscured. Today I finally got around to doing it. Here are download links: (they are about 17 MB each)
- Osiris for Windows (Installer-less version)
- Osiris for Mac OS X (PPC only, sorry)
The system requirements are pretty modest: a 1 GHz processor and a 32 MB video card should play the game just fine.
Here is a medium quality WMV video of me playing the game for a few minutes: Osiris Video. It's a big file but it should stream OK. Here's a low-quality YouTube copy:
The purpose of the game is to teach the basics of a freshman 'Archaeology 101' class. You play the role of a college professor who organizes an Egyptian dig and are supposed to learn how to do the following things:
- Acquire funding
- Create a team of graduate students, specialists and local workers
- Manage the digging process to maximize efficiency and minimize artifact breakage
- Fend off attacks from mummies, crocodiles, scorpions, thieves and evil genies
- Manage team morale and energy while keeping within the budget
- Interpret your findings
- Publish your results in respectable journals to increase your prestige
Here are a couple of screenshots:

FSAA mini-benchmark
Have you ever looked at the FSAA settings in the control panel for your graphics card and wondered what the real visual difference is between them?

I was curious myself and decided to do a mini benchmark test. I pulled up a game I wrote a while ago called "The Adventures of Bruto" where you fly around as a dragon and fend off a naval attack. All of the graphics in the game are vector images, so it is a good visual test case for FSAA:

I took screenshots of the game at each FSAA setting level for a comparison. Here are closeups of the castle at 0x, 2x, 4x and 8x:

0x

2x

4x

8x
Overall the screenshots seem to confirm the idea that "more is better" when it comes to FSAA, but once you get past 2x the improvements don't seem to be that noticeable. I'll probably leave games on 2x or 4x and bump up other settings like model/texture detail if I need to make a tradeoff.
