6/29/2007 Sim Pilot Magazine There's a new online FS magazine in circulation that has caught my attention: Sim Pilot Magazine. Run by a fellow FS developer Christian Stock, issue #1 covers some very interesting ground. They review Digital Aviation's Dornier 27 (which just got released for FSX, BTW), evaluate the flight dynamics differences between FSX and X-Plane, and a few other nuggets of great FS verbage. Check it out!6/28/2007 The Jet
The Jet. Cirrus Design unveiled their newest concept aircraft to the public today and it is nothing that I imagined it would look like. The V-tail is a nice touch. What do you think of it? I see they are continuing the tradition of dual doors, an uncommon feature of the latest VLJs. Will it be as successful as the SR-20 & SR-22? Only time will tell. 6/27/2007 Barrington makes it homeBarrington Irving completed his around-the-world expedition this morning with an eventful arrival into Opa Locka airport. Ron Hamilton and Bob Hayes were two of several hundred people who greeted him with a huge celebration, complete with CNN and CBS news coverage of his arrival. Be sure to stay tuned as to more news surrounding Barrington's flight is sure to follow! 6/25/2007 Further paint tweaking of Twin Comanche in FSXWhile we were in Batavia this weekend, I realized that the predominant color of Roy's chromalusion paint is really a teal color (shown below) and highlights a bright purplish magenta color.
So, I spent today modifying my textures to represent this, and I made a quick video of the results. 6/23/2007 A trip to Sporty'sRoy was kind enough to invite me along on a flight to visit the home of Sporty's Pilot Shop in Batavia, Ohio today. It just so happened to also be a CFO fly-in where the AOPA Catch-A-Cardinal would be displayed with a (nearly) complete airframe.

The view of short final into Batavia.
Roy and I were lucky to have run into Sporty's President Michael Wolf when we arrived, and he gave us a sneak-peek at the Cardinal.
Sporty's founder and Chairman Hal Shevers insisted that Roy's plane be parked next to their 2007 sweepstakes plane and with a wave of his hand, several Sporty's associates moved Roy's plane within seconds.
While we were waiting for the "official" events to kick-off, we saw this beautiful P-51D Mustang depart the field. We later spoke to the owner, and said the plane would be making an appearance at the Gathering of Legends.
This weekend marked the 150,000th hotdog given away by Sporty's in appreciation of their customers.
Julie Boatman taxied the Catch-A-Cardinal up to the main Sporty's terminal so everyone could get a closer look. She was kind enough to pose with the plane and I.
We were all surprised to see none other than AOPA President Phil Boyer fly in to get a first look at the Cardinal in a nearly-complete state. Julie was proud to show him the great progress first-hand. Phil and Roy enjoyed reuniting with a brief conversation.
And finally, Hal Shevers (on the left) and Michael Wolf (on the right) pose for a photo with me in front of the Sporty's Pilot Shop. What a great pair of gentlemen to host such a great event! If you are near Batavia, Ohio (I69) on any given Saturday, be sure to drop in for your free dog and check out Sporty's, it is a first class operation.
6/22/2007 Jeppesen SIMCharts 4.0 price reduced & unlimited subscriptionNew from Jeppesen is version 4 of their SIMCharts add-on for Microsoft FSX at a reduced price. Originally released in November of '06 at $59.95 USD, the price is now $41.95 USD with an unlimited subscription duration! Some FAQ information: Does SIMCharts by Jeppesen offer paper enroute charts? No. Unlike version 3, paper enroute charts are not available. Jeppesen provides Microsoft with a customized extract of its "NavData" (aeronautical navigation database). This NavData is used by Microsoft to render the enroute segments of the flight. Since there is a very high correlation between the information contained in the NavData extract and Jeppesen's paper enroute charts, the use of paper charts is no longer deemed necessary. Are all airports included in SIMCharts by Jeppesen? There are over 25,000 charts available in SIMCharts 4.0. We have included almost every airport that has a 6,000 foot or longer runway and a Standard Instrument Approach Procedure. How realistic are SIMCharts by Jeppesen? SIMCharts are real Jeppesen charts, the same charts that are used by professional pilots around the world. The only difference is that they are not current and hence are for Simulation Use Only. Why isn't there an upgrade from v3.0 to v4.0? The entire chart library in SIMCharts v4.0 has been updated to match Flight Simulator 10. This means literally thousands of images have been updated - it's essentially a new product, and therefore, an upgrade isn't available. How does SIMCharts v4.0 differ from v3.0? SIMCharts v4.0 is a web-based service. There is no physical product associated with the new service so no worries about lost, late or broken CDs. Users request and retrieve charts through an interactive Internet session when using Microsoft Flight Simulator v10. Downloaded charts can be printed, saved to disc or discarded at the user's discretion. Will SIMCharts v4.0 work with Microsoft Flight Simulator (FS) 2004? No. SIMCharts v4.0 uses entirely new technology and protocols for serving up terminal charts. It also utilizes new protocols associated with Microsoft's version 10 Flight Simulator and the technology is not backwards compatible. Why are the charts not current? SIMCharts uses Jeppesen Terminal Chart cycle 02-2005 to match the navigational data used in Microsoft Flight Simulator X.
Screen captures can be viewed here. 6/21/2007 Short video of Twin Comanche paint flip in FSXI had a request to get a short video up showing the color change on the Twin Comanche, so here it is! 6/20/2007 More advice from AdrianSo you thought that polygon counts are not as important as they used to be. Well, according to Adrian, you are right ... sorta. It is vertice counts that can get you! Adrian does a much better job of explaining exactly what this is all about in his latest blog entry called "Performance Art 3: Polygons don't matter." He uses examples that pertain to scenery objects such as buildings, but the advice he gives most certainly applies to aircraft models. The take home message is pretty simple: snap those vertices on the model, use the least number of smoothing groups as possible, and make sure your vertices on the UVMaps are snapped as well! Happy modeling!
FS community mourns loss of Ron Freimuth News has quickly spread about the passing of flight dynamics expert Ron Freimuth. Several examples of his work can be experienced with the Dreamfleet Archer II, Cessna 177 Cardinal, Boeing 727, T37 Tweet, Feelthere Caravan, and many other freeware and payware packages. He was an active participant at AvHistory.org, where participants strive to attain realistic flight behavior within 1% of the real aircraft.His contributions to our hobby have been great and he will be missed. Rest in peace Ron. 6/19/2007 Barrington on US Radar!After a long wait at Schemya, Alaska, Barrington made it to Anchorage on Sunday. Today he is enroute to Juneau and is on US FAA radar for the first time since March 30th! Barrington is attempting to make it to Seattle, but I understand a bit of rough skies are between Juneau and Seattle that is a little too much for the Columbia 400 to "weather." His reception gala has been postponed due to his long stay at Schemya, but with the progress he is making, I'm sure it will not be pushed back too far. God Speed Barrington! 6/18/2007 More Twin Comanche in FSXI did some further tweaking of the ChromaLusion paint...
This is looking at the fuselage at a normal angle. I realize that real chromalusion paint works based upon the angle of viewing, but this specular technique is the best possible means to replicate it within FSX. Here we are with the light reflecting from the sun toward the viewer, allowing the magenta below the blue to shine through brilliantly! I love it! 6/16/2007 First glimpse of TC in FSXI'm in the process of getting the Twin Comanche going in FSX with a true FSX aircraft model, and I've been working on the specular maps today. I was so delighted with the results, I thought that I would share the first public image of the Twinkie in FSX! Be sure to click the picture for a slightly larger version. I have put one of my former FS9 images up just as a comparison of how the specular map is really making the ChromaLusion paint really flip flop. FSX FS9 6/15/2007 Latest buzz
There's a lot being said lately in the FS blogosphere...
Have a great weekend!
6/14/2007 Twin Comanche fly-by
When Roy and I returned from Griffin yesterday, he asked me to get a video of him doing a fly-by so that he could hear what his airplane sounds like from the outside. Everyone has told him that the aircraft sounds incredible from the outside (and it does), and he wanted to get a taste himself. I thought that I would share the video on soapbox, so here it is (my debut video baked in Windows Movie Maker). Crank up your speakers and enjoy!
6/13/2007 Griffin and a CardinalBefore I get to the topic at hand, let me give some background on how things unfolded. My good friend Roy Wilbanks was out at the airport on Monday morning updating his GARMIN GPS databases when a slick Globe Swift taxied up to the FBO. Roy stepped outside to get a closer look and struck up a conversation with the gentleman who had flown her in. During the conversation, Roy asked where he flew from and where he was headed. "I came from Griffin, Georgia" said the gentleman. "Griffin, Georgia!" Roy exclaimed. "That's where that AOPA Cardinal is!" The man agreed. "Yes and my wife is in charge of that aircraft." It turns out the gentleman is the husband of Julie K. Boatman, technical editor for AOPA Pilot magazine, and project lead for the Catch-A-Cardinal sweepstakes plane. Roy then proceeded to let Mr. Boatman know that he was the recipient of the 2004 AOPA Win-A-Twin Comanche. Mr. Boatman had dropped Julie off in Griffin and was on his way back to Frederick, Maryland. It was blind luck that he stopped in Greenwood at the very moment that Roy was there. Roy calls me and says that he wants to fly over to Griffin to see the Cardinal and meet Julie. Christy Lake had been under the weather earlier in the week, but she was okay to go to daycare and I had finished all of my household duties, so I was in the clear to ride along this morning. So we hopped into N204WT and took off.
Skies were clear with visibility around 10 miles, so we flew VFR.
When we arrived in Griffin, it was pretty easy to spot the Cardinal from the ramp, so we pulled up and parked next to the hangar. The Cardinal is currently getting an engine overhaul and other structural modifications and refinements.
Here you can see the thousands of signatures that were gathered at Sun-n-Fun. Jim Rhoads from Flight1 was one of the signatures I saw pretty clearly.
Roy and Julie posed while I grabbed a couple pictures of them together in front of the two aircraft.
On the flight back to Greenwood, we were greeted by numerous clouds that were hovering around our cruising altitude of 5,500 feet. It was great fun weaving around them to stay VFR legal. Check out how the prop looks like it is bent in my photograph. Pretty cool, eh? It is not everyday you get to meet someone as famous in the aviation community as Julie K. Boatman. For the three years that I have been an AOPA member, I have enjoyed reading her articles. Getting close to the Cardinal was a treat as well. It sure is shaping up to be a very nice aircraft. If you are a current member of AOPA, perhaps you'll be getting a closer look from behind the yoke when they award it next February!
6/12/2007 Project Do-228 is alive and well
6/11/2007 Barrington makes it to Alaska Mike Singer has a nice write-up about Barrington's trek from Japan to Shemya, Alaska, complete with screen captures of his flight on the tracking map. Barrington made the trip Saturday, and wrote an entry on his blog describing the flight. Be sure to check it out! Experience Aviation is planning a welcome home gala on June 23rd in Miami. If you are fortunate to be able to attend, it surely will be a grand celebration!6/8/2007 Some helpful hints and insight from Phil Phil Taylor keeps the ball rolling with his weekly FSX tweaks and tips posts. This weekend, we are treated with two topics: "AI at 80% max" and "Water slider and FPS costs." In "AI at 80% max," Phil makes a stern suggestion to never raise the AI population above 80%, and he gives several good reasons why. In "Water slider and FPS costs," Phil explains the exact effects and demand on the PC for any given water detail complexity. This information is great for anyone who wants to weigh out which is best to use. Personally, I stick to the 1.x settings. Every once in a while, I'll bump it up to 2.x low for some minimal reflections, but I really do not fly that close to the water (when I am near water) to really tell that much a difference.On a side note, my good friend and Eaglsoft colleague Bob Hayes is visiting me this weekend. He and I are going to be doing some technique sharing for model design. I hope to get a few photos of us to share while he's here. Have a great one!
6/5/2007 Quick(er) draw calls Adrian Woods published a very enlightening article elaborating how draw calls affect performance, thus he titled his post "performance art." 3rd party developers, this article is for you.Adrian states that often they (MS) are blamed for the poor performance of 3rd party content, as in the past they have not written in the SDK documents how to gain the best performance out of 3rd party wares. He's venturing out to reverse this by passing along better techniques and advice, and this is a great start. Adrian explains that for each change in a material, such as glass or chrome, a different draw call has to be issued. His explaination of how 11 1024 bitmaps for a single FS object can quickly become 330 draw calls in some situations, a third of the total ideal budget for draw calls, is a huge wake-up call for me. I know that I have been guilty of sub-optimizing the whole by optimizing the part, and I have been working to be more mindful of how performance will be affected by what I'm doing at the development level, the art level. Now I have some rhyme to the reason. The take home message is best stated by Adrian himself: "...as often as possible, use the textures to change the shader values as opposed to using the shader constants themselves. If you control reflection in the diffuse alpha and specular in the specular color and specular alpha, then you should be able to set the reflection and specular power term constants at max and use the texture values to adjust accordingly. You should be able to get rubber, metal, plastic and other surfaces in a single draw call just by adjusting the various portions of the textures. The only thing you should need new material constants for is something like glass, chrome or an object that is transparent or glows." Here Adrian is exploiting the awesome flexibility of the new shaders in FSX. Instead of having a material set at one specular level for a particular texture, and having another material with a slightly different specular level for the same texture, now consolidation of these specular levels onto a single material is possible. So the name of the game is to have an absolute minimum number of individual materials per project, period. That is the secret to good performance. "Also, make sure that all of the material textures are grouped. Put all the chrome on one sheet, because then you can have a single chrome material and a single chrome draw call. Do the same with glass, metal, etc. If you have 11 1024x1024 textures, and each of them has a chrome section, then you are forcing 11 new draw calls when you could have one." This is some of the best advice I have seen in a long time, and the explaination is right on the money. Many thanks for passing this knowledge on, Adrian. I'm anxious to see what else you plan on revealing in the coming weeks.
