Does reflection of light by canopy need DX11?

[bienenbaer]

Oleg posted a BoB rendering of a Spitfire that showed the sun-light strongly reflected by the front-shield of the canopy. This seems to model early visibility of planes by reflected sun-light, which makes the game much more realistic.

Not strictly related to BoB, but I read that sightings of US planes by Luftwaffe pilots were often due to this effect (not from the canopy but from the silver fuselage), as were sightings of MiGs by US pilots over Korea.

If this was a game feature, would it need a DX10 or DX11 card to actually have it in game? (I heard Bob would not be OpenGL anymore)

Not sure what you mean, which screen shot are you referring too?

im sure it could be done with directx 9 or 10, directx11 is mostly just tesselation, unless you make a game specifically for directx11, that uses the new open source API's and stuff... and BoB doesn't.

A friend showed me a Spitfire shot with open canopy banking at sunset or dawn ... cannot dig it out right now.

But the effect is perfectly shown in this screenshot as well:

Don't know, how Oleg setup BoB but it should mean that you can see the plane from a much larger distance ... as a small flickering light, not as a dark spot as in il2.

Now we do not know what the Sim will contain or not, but only from the graphics engine, does the effect need DX11, DX10, or DX9?

As for reflection from a metallic plane body, that's in the Stuka vid

Does anybody know?

S!

Rise Of Flight is not DirectX 11 and has reflections etc. Go figure

Nearly every screen shown so far was DX9, so I wouldn't worry. It certainly provides the required featureset. Not sure if far-away objects will still show glinting canopies but it sure would be nice.

What your seeing is HDR & bloom effects, been around since DX9.
