How to set up accurate real-life depth and convergence? Realistic 3D perception
Hi,
I'm trying to find a guideline or formula to set up games with realistic and real-life 3D perception. To represent a scene as you would see it in real-life. I have some examples to start.
With max depth and default convergence, Far cry 2 has an almost accurate depth. You can judge distances realistically, and you can see the gun as if you are holding a real one in front of you. However, COD4 doesn't have a realistic depth. You have to increase convergance to make it look real life. Same thing with F.E.A.R, wrong convergance. Left4Dead is another good example. With latest driver 186.18, you have to decrease the depth from max to make L4D look real-life. Earlier drivers had an accurate depth for it.

You might argue that more than 40% depth or so is painful to eyes, but that doesn't mean what you are seeing is a real-life accurate 3D representation of the scene. Depth and convergance are subjective from person to person, but what the person perceives may not be accurate 3D. That's why I started this thread to find a way to set up 3D so that it looks real-life (ignoring eye strain and headaches lol), and it can be measured or something.

I've always played with maximum depth, from first day I got my 3D kit. 30% or 50% depth looks beautiful, but not real. I never get headaches or eye strain.

lol lucky you =) But I guess I just need time of experience to adjust myself to the new world.

Try this utility, and see what you think. It was created by InThree, and they specialize in doing 2D to 3D conversions for cinema.

From what I figured out:

I don't know how many % that is.

Great links guys. I haven't downloaded the In-Three Depth Machine yet. I'll download it tonight. Looks impressive.

i always play with max depth too. However with convergence at the higher settings, it feels as if you are playing with toy characters. What i mean by that is that while things look closer, they tend to look smaller. So generally i start with high convergence and lower it until my avatar looks like a normal size human. (or whatever he happens to be) :) It seems to be the method that works best for me anyways.

I do exactly the same. Start with max depth and convergence and lower it till I find realistic one. I've also noticed that after playing around with convergence and depth settings, I can see a lot of "pop out of screen" effects in my games, especially the weapons.
