I have a question forthose who do the design work on computers for all the aircraft we get to fly now in FB ( or those who know how its done...) I understand that the "platform" for Ubi's future Bob will be different...does this mean that the a/c will be better rendered? It is hard to conceive of something better than ,say, the new Gladiator , in the Aces add-on, but I simply don't know what you PC Boffins are capable of .Can you or Oleg explain what the future might be capable of bringing? I'd appreciate the peak!

There's quite a bit I look forward to seeing in BoB.
The FB engine, glorious as it is, has runs its course. It doesn't have specularity mapping or bump mapping, nor per-pixel shading. (tho sometimes I wonder looking at these planes http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif)

Basically, specularity mapping defines shinyness in the same way that a skin defines colour. Aluminium surfaces are shinier than cloth, so you may make your early Spitfire's fuselage shinier than the canvas covered rudder (if I remember my Spits correctly). This won't make THAT much difference to how planes look from the outside, but it would make cockpits much more interesting.

Likewise, normal or bump mapping does exactly that, maps bumps onto a surfaces. Normally, if you wanted every rivet to be slightly recessed, you would have to build your model that way, i.e. define the recesses in geometry. But in games, you cannot do that because of the restriction on the number of polygons in a model. Bump maps allow you to fake things like that without increasin the poly count. I can get more technical if you want, but I don't want to bore anyone http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

I'm not a 1C developer though, so I don't pretend to know what they're going to do for BoB, but the above are standard of the industry now.

There is lots more that can be done in terms of lighting, shadows (in-cockpit shadows, for instance), damage effects, etc.

Perhaps when someone has said differnet "platform" they infact mean a different engine. Engines are the behind the scenes plumbing that let the developers plug in physics models, flight dynamics, weapon types, and that sort of thing. The FB engine has pretty much reached a pinnacle..its doing some things now that it was never designed to do from the start. Usually when you reach that point its time for a new engine...because its more efficient and you can design it with the features you now support and new ones you want in mind.

Visually I'm sure the aircraft will look more real (more specific specular lighting, reflections, self shadowing, bump mapping, 24bit texture maps). That sort of thing will surely be upgraded and changed.

128-bit colour would be an advantage for rendering skies and contrast between planes and background textures. Shaders will help model nice herds of cows that flee before your .50s. http://ubbxforums.ubi.com/infopop/emoticons/icon_wink.gif

I'm pretty sure Oleg said that the ability to depict grass was written into the IL2/FB engine from the start- it's just been disabled for FPS reasons. I wonder whether it could be enabled by a small patch in about 12 months time?
