I HAVE BEEN INTO THE RIFT. AND I HAVE TO TYPE IN CAPITALS, BOTH BECAUSE I’M RENDERING, BUT ALSO BECAUSE THAT IS HOW AWESOME AN OCULUS RIFT IS.

It REALLY only works in the Rift

I AM A SPACE FANBOY … WAIT … Rendering is Done now. Okay. Again; I am a space fan boy ever since I was a little kid. Everything space is awesome. I was so full of myself. I actually looked down on people who couldn’t name at least nine planets. And their moons.

Now, these days there are so many inner-solar-system objects with a name, that I can’t keep track anymore. Ever since Pluto became a dwarf planet, we’ve started naming every rock in the Solar System. Still, When exploring them with an oculus rift is AWESOME!!!

Gnuif, before he dives into Ciess

Also this post on Oculus Rift Forums, that may help some people;

Actually, you can do real time image manipulation

Okay, with After Effects you can get a convincing Oculus Rift 3D view, by using the “CC Lens” (I think the CC-effects ship with After effects).
By Trial and error I found that a CC Lens, centered in the middle, with a Size of 60 and a Convergence of -100 will give the desired effect.

Now I had my Rift on loan for the weekend a couple of weeks back, so I can’t experiment with it anymore, but here is the simple setup, that worked for me.

The CC lens will emulate the HMD warp shader’s lens bending, and by creating 2 camera views in After Effects you can emulate, or recreate a z-buffer. I’m assuming that a HMD Warp shader can be easily set up with Adobe Pixelbender, but I did not have time to test that out. So here is the walk through of a poor mans HMD Warp shader in After Effects CS4

1) First create your scene, you only need 640 pixels in width, but I created mine in full width at 1280 pixels ( x 800 of course). It doesn’t really matter as we will be cropping it later on. Make sure your scene has 3D objects in it, moved along the z-axis, otherwise it would be pointless looking at it in the rift ;)

2) Drag your scene-Comp scene into 2 new compositions ( which are 640×480 ) make them a 3D layer, add a Camera and let the camera look at the scene-composition you just dragged there.
Now Position the camera’s slightly apart in each of the compositions. I have mine in the ‘left’ composition at 400,400, -1777 and in the right composition at 300,400,-1777. I assume that by playing with the x (moving them further apart) you can make the depth of your scene more profound while viewing it in the rift.

3) make a final composition, 1280×800 and put your 2 camera compositions in it, next to each other. Now apply a ‘CC Lens’ – effect to each composition and put it on size 60, Convergence -100. I found these values through testing, so they might be optimized, but they worked for me.

4) Finally, Render the scene and view it with the Oculus Rift.

5) Profit :)
