Week 1: Nuke 3D and Camera Projection
Basics of NUKE’s 3D viewport
NUKE’s 3D side is almost identical to that of Autodesk Maya.
Camera Projection Method 1
I applied an image to an object in my viewport and animated the camera so that it looked like someone was walking towards that image when I watched the playback in the 2D viewport.
Using my newfound knowledge I applied this workflow on a much larger scale where I projected images of the same prison cell from different roto scoped angles to form a 3D room.
Projecting my camera this way looked more authentic because I had more dimensions to my object in the 3D viewport.

This is the object browser where I can select or see everything in my viewport such as tracking points. I can also rename them to maintain an organised workflow.
This is the Attribute Editor where I can adjust my scenes render related settings and import my sequence.
The Timeline
The different workspaces 3D Equalizer has.
Importing my image sequence using the Attribute Editor.
Caching my image sequence to ease the performance strain on my PC.
I selected these settings for my scene
Control and click to create a mask, once you shape it press G so it can be ready to tracked.
Press “E” to set a keyframe on the timeline.
The Deviation Editor, it helps me better visualise where my masks detach from their designated object while playing my video.
Tracking my points in a 3D environment (alt-C to open), there has to be a minimum of 8 tracking points for this to work.
The 3D viewport is opened by pressing “F6”
Adjusting my parameters by setting them to adaptive. (Press alt-6 to open)
I can use my 3D point racked data to adjust any deviating tracking points.
Week 4: Applying week 3’s task using 20 tracking points
Week 5: Tracking a scene to place a 3D object in it
Week 6: Nuke – 3D Equalizer Workflow
My objective is to import this cylinder into Nuke’s 3D workspace so I can I adjust to look like it fits into my 2D footage.
I will export my tracking markers as objects simply to use them as a reference as to where my mesh would belong in my 3D space in relation to that of my 2D.
The red circled nodes are there only as a reusable reference so I do not have to import my 3D equalizer assets manually every time compared to copy – pasting them using this method.
I added a card to test this method in a rotoscoping pipeline.
Week 8: Surveying Data
These are real world dimensions of my scene recorded during the production process.
Using the image’s dimensions in the real world I was able to add tracking points in the 3D space to align them accordingly.
Connecting my tracking points through a 9 image sequence
Firstly, I added a tracking point without tracking it in the first image and found it again in the second image and placed it there. Finally, I repeated the process for 29 more points.
Note: not every image needs to have the point visible, in that case, the image was skipped.
