Nuke was made for stereo. Even before its support in version 5 Nukes flexible node sytem seems
to be the perfect way to cobble together a way to make any thing go which way.
But if your in a pinch or are new to stereo Making your own custom rig may seem like a Daunting Task.
So here is mine, I hope you have fun with it.
Under The Rig Control node
This Node Controls the Rigs Movement
Key frame or Parent a Solved camera to the RIg.
For cameras with Variable Focus you Can parent the rigs focus controls under the Solved Import tab.
Enjoy The ability to nondestructive adjust the camera on top of a monoscopic solve data
Toe Slider- to adjust convergence – Leave at 0 if you want a parallel rig
Inner Axeal – Also Known as Inner Ocular when Refuting to the Human Eye, Slides both cameras away and towards each other horizontally.
Rig move – this is a quick peak where the axis is sitting and gives you the ability to parent the rigs position
— Indie Tab
Left Indie – moves the Left camera Independently from the Right non destructively to the inner ocular
Right Indie – Moves the Right camera Independently from the Left non destructively to the inner ocular
Left Rotation Indie – Nondestructive Rotate the Left
Right Rotation Indie – Nondestructive Rotate the Right
This is the same as what you would find in the Camera Projection Tab, Adjust the Focal, Aperture ect
A quick tip useful for any heavy Nuke User is how to find a Node you created in a complex Node Graph.
By hitting “/” while hovering over the Node Graph
Proms a Search window where you can type in and search your to your hearts content.
Now combined with the tab menu you’ll be blazing away through your comps like a pro.

Nukes has a great 3d environment along with solid 2d node based composting, these tools can seem to live in different worlds. On one side, 3d the other 2D. Getting things out into 2d from 3d can like a daunting task if your not familiar with The reconcile 3d node. Lets Take the Godrays node for an example. allot of the times the point you want to project from is not on a plane of parallax visible in the plate, more a point in 3d Space off in the distance. You can animate it by hand but, if you can solve a camera its easier than you think.
So fire up nuke and hit that tab key as you type in R-e-c-o .. to pull up the the node like a pro.
You’ll notice that there is a few handles that are attached with it. Img, Camera, Axis. The most important of the handles to focus on right now is the Axis, where it observed by the solved(or animated) camera is where its going to back out the X,Y coordinates. Click and drag the axis and orientate it in space where you want you ( for this example) god rays to project from and attach the other handles to assigned names, Now from this you’ll have a few choices.
You can hit calculate key frames to have the computer look through the camera and give you the x,y values and bake it out. or you can have it update in real time and link an expression (apple drag, sorry windows folks i can only tell you from a mac at this moment) to the x,y transforms to the parenting node.
Either way this node is amazingly simple to use for all you xy converts.
The Reverse Process – Points to 3D (from xy to xyz)
Now you say hey Nate that’s great But I need to translate a point in 2d to 3D. This process can be done a few ways, what comes to mind is placing things in by hand, not a difficult process, in most cases but The foundry has your back with a node specialized to do this – Points to 3d. The min you get this node on screen you quickly observe that is has a camera handle like Reconcile 3D and relatively its the same process, take your solved or animated camera and attach it to it. From there you notice in the node option s it has Point A, Point B, Point C. These are the 3 Points you need to feed into the node to find the point in 3d space. So scrub through your timeline where you see your object, space or thing(er mo bob) and set the 3 points on 3 different frames, and voila there you have it. Your 2d values mapped out in 3D space.
