This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

Here's what the z-depth looks like directly from maya's renderer.

Man.. did you ever loose me there.. LOL .
Ok after i figure out how to extract an image that looks like yours i blur it in photoshop? then how do i use that to Blur DoF my maya file?

Anyway, you're kind of on right track with what you suggested yourself. Only that I'd use after effects instead of photoshop. I'll play with this tomorrow more. It's too late right now :/

Create two nurbs spheres @ 1 1 -5 and @ -1 1 5
Create a nurbs plane @ 0 0 0 and scale it up by 25
Create camera @ 0 1 15
Select Display->Camera/Light Manipulator->Clipping Planes (so that you can see what the next few settings do)
Uncheck the camera's "Auto Render Clip Plane
Set the cameras near clipping plane to 3
Set the cameras far clipping plane to 28
In render globals set:
- File Name Prefix: zDepthTest
- check the "Depth Channel(Z Depth)"
- change the camera from persp to camera1
- Resolution Preset: 640x480
- Anti-aliasing Quality Preset: Production
Batch render the frame
The Photoshop approach (not very good imho. if someone knows a better way i'd like to hear)
-------------------------------------------
open the zDepthTest.iff in photoshop (hopefully you got the maya iff plugin for photoshop. it's free but i can't remember where i found it). in photoshop select Window->Channels. you should see channels RGB, Red, Green, Blue, Alpha 1 and Alpha 2. Alpha 2 is the z-depth channel. click on it and zoom in to one of the spheres edges. it's all jagged and aliased. Do a gaussian blur with a radius of 1,0. Much better. Now zoom out to 100%. Control-click the Alpha 2 channel. The selection marquee looks a bit weird but let's ignore it. Choose Select->Inverse. Click on the RGB channel. Now start blurring with the selection still active and you should see the DOF like effect showing up.
The After Effects approach
-------------------------------------------
AE can read Maya IFF files but it can't (afaik) access the Alpha 2 channel (the z-depth info). Render the scene to an RLA file which is more suitable. Import the zDepthTest.rla in to AE and make a composition of it. Now apply an Effect->3D Channel->Depth Of Field. Nothing happens until you start tweaking the settings. For example:
- Focal Plane: 0,2 (this is the focus distance. keep withing 0 - 1. 0 = far, 1 = near)
- Maximum Radius: 5 (this is the max blurriness)
- Focal Plane Thickness: 0,1 (like focus region scale in maya. keep within 0-1)
Now you should have the furthest sphere in focus while the other is blurred. Change the focal plane to 0,7 and the foremost sphere should be somewhat in focus.
There you have it... I hope
