Week 1: Nuke 3d and Camera Projection

messing around with scene and camera on nuke

adding motion blur for the animated movement of the camera

for this exercise we assigned a image to a cylinder and using camera movement to make the image have some type of depth of field

to do this we first make a cylinder geometry and a project 3d node to assign the image onto the geometry next we then make a scanline render to render out the video, the render cam will be the camera that you animate going down the tunnel as for the project cam that was made the purple circle will be the static camera what you will then connect to the project 3d image. and the green one highlighted will be the opposite of what i said for the purple.

changing the cylinder to 90 degrees

first we started by masking out every section of the cell

next we then added them to a scene using the 3d camera and making a geometry out of 2d shapes so when using the camera scaling in the cell it creates depth of field and gives the illusion as if we are actually going through it.

 

week 2

roto the section that should be static and easy to track because water is hard to track

next you will the use the camera tracker to track the points that were placed

you will be presented with  red and amber tracks so to remove them you will now press delete unsolved and delete rejected

you will then now go into vertex selection and select two point and put the position onto the card

week 3/4 : 3D Equalizer

going to scene and double clicking will then allow you to head to browser to find you clip you want to import.

heading to playback and selecting export buffer compression file will make you see the video smoothly

going back to the section were you clicked to import your video you will then go to the lenses section and click on that to change the lens of the camera

changing the filmback width to the camera used what you can find by searching the lens of the camera what was 3.6 cm and changing passive to adjust on the same row

focal length to 35 and fixed to adjust

name of the camera being utilised 5D mkiii 35mm

clicking crtl and right click will apply your tracking then also pressing g after will then gauge the marker

after finish tracking we went back to the lenses settings then went to camera

then pressed the drop down on the camera constrains

and changed it from no constraints to fixed camera position constraint

after coming out i then clicked alt c to bring up the camera in a 3d space showing me lines to prove that its calculated

going back to the lenses

changing lens distortion model and changing it to 3de classic LD Model

navigate to windows bottom left and go to parameter adjustment window

then we are going to remove the filmback and pixel and leave focal length then select adjust this will then gives us better info on the video.

on the lenses setting go to lens distortion and tick the distortion and quartic distortion

manual tracking

lineup control

selecting 3 point on the floor

tracking was done in 3d equalizer and rendered out as a mel file for maya to now add my object i added to object well first i done a render of groot with this video and a cube. video will be shown below 

using aovs in After effects to now colour grade the geo’s

I encountered some issues with the render in Maya, where the cube appeared but the shadow matte underneath was a black plane that could be seen in the video. I chose to create another one using Groot and export it using only Groot and the aovs, which worked, but I messed up the lighting on the right side.
