DOF Settings

[wmaass]

Playing with DOF settings with FrameWerk. I can't seem to find settings that are satisfactory. For example the settings found in the tutorial (that does not use FrameWerk) produce en entirely blurry image.

 

fw.GetRenderer().SetNearDOF(true);

fw.GetRenderer().SetFarDOF(true);

fw.GetRenderer().SetNearDOFRange(Vec2(10,15));

fw.GetRenderer().SetFarDOFRange(Vec2(25,30));

 

Anybody have any experience with this? I want near objects to be in focus.

You might want to take a look at the DoF video Josh made on his blog/the wiki.

To keep the near objects in focus, you want to set the FarDOF to make things in the background blurry, so:

fw.GetRenderer().SetFarDOF(true);

fw.GetRenderer().SetFarDOFRange(Vec2(5,8));

fw.GetRenderer().SetFarDOFStrength(1.0);

 

This will make anything past the starting point of 5 meters from the camera blurry... its hard to tell if the ending range makes much differences other than it obviously needs to be a higher number than the starting range. I assume it does a gradient of blurring between the two ranges. The strength is what is crucial and sets the amount of blur, where it appears 1.0 is the highest value and 0.0 is the lowest.

 

***Edit-- wmaass, are you using bmax? If so the commands you need are:

fw.Renderer.SetFarDOF(1)
fw.Renderer.SetFarDOFRange(Vec2(5,8))
fw.Renderer.SetFarDOFStrength(1.0)

Thanks guys for setting me straight. Macklebee, I normally use BMax but for this project I am using c++.

[wmaass]

Hmm, still getting poopy results. The best I can do is lower the strength. Here are some shots at various settings.

[macklebee]

are you still setting your nearDOF as well? if you are, don't.

 

here's what i get with a range set at 5,8 and the strength at 1

 

[wmaass]

That is what I am looking for, not getting it though. I'm only using farDOF and I should mention this is 2.27. I have 2.3, just have not bothered to update this project to it.

 

fw.GetRenderer().SetFarDOF(true);

fw.GetRenderer().SetFarDOFRange(Vec2(5,8));

fw.GetRenderer().SetFarDOFStrength(1.0);

actually that example is from 2.28 and its bmax... i will try the 2.27 and see if that makes any difference for me...

[macklebee]

here's 2.27 with the same settings... its working fine for me in bmax... it really looks like the neardof is on in your screenshots... or are you sure you are actually close enough to the tree so parts of it are closer than the start value for the farDOFrange?

 

[wmaass]

I must be doing something wrong. I might try BMax. I took the nearDOF stuff out. I can try a simpler app, this one has a bunch of other non-LE related code in it. I'm right on top of the tree in this shot.

[wmaass]

Here is the image.

[macklebee]

Here is the image.

 

huh... thats really weird... maybe something else is conflicting? or its a problem in C++? any way you can try a simplified example in C++ and bmax to determine if its language related?

[wmaass]

Here is simplified version using c++. Thanks for your help by the way.

return Terminate() ;
}

[macklebee]

turn off all of your other postprocessing like bloom, ssao, hdr, distancefog... and see what you get... if its good turn one back on at a time and see what happens

 

actually i would still load your scene... a stationary camera looking at one cube will make it hard to see DOF

[wmaass]

You got it, it was the HDR borking it. Check it out now. Thanks!

[macklebee]

hey that looks nice...

 

weird. it seems maybe there is an issue with c++'s hdr?

 

I don't have that problem in bmax...

I have the same problem with C++, HDR effects the DOF, but no problems with it in Bmax.

[wmaass]

Interesting. Must be something different between the versions of Framewerk.

[DaDonik]

I also have this problem in C++.

Looks like it's an Framewerk issue, when it works in BMax.
