You may first get a blank screen, to change it to the basic window setting, go to
Environment>Basic
The user interface will be reset to the basic interface.

 

.   

Close unnecessary tabs to create a larger working space.

 

You can either select the buttons on screen or create shortcut hot ksys for ease of use.

 

Set your shortcut keys for a more efficient way to operate.

 

To set shortcuts, set hotkeys for all buttons shown above, as these are generally the buttons used in most cases.

Right click the button to be changed, select “Define Shortcut”.
The dialog box shown above will appear.
You can now change it to a new shortcut of your choice.

 

In this example, I’ll be changing the “Track” button shortcut to “T”.
Select “Acquire Shortcut” and press “T” to set it.

WEEK 9
Filming 

 

Today we went out filming for our second assessment.
We took quite a few shots.

We did surveys ourselves.
We placed markers for tracking, and took measurements things in the seen for distance constraint accuracy, which will be used when tracking our shots for the scene.

 

     

Measuring doors, and plate numbers, edge to edge.

 

    

Measured letter boxes.

 

  .   

 

.   

 

Even measured the sign posts, and a mat on the floor.

1ST ASSESSMENT

 

Original Video before Tracking

 

Survey Data 

 

 

 

___________________________________________________________________________

 

 

.   

Started 3DE4, and changed the UI to “Basic” under the Environment menu.

 

.   
Then cleared unnecessary tabs for more working spaced.
Under Camera, I load the Pillars_Table sequence, then changed the FPS to 25Frames Per Second.
I then changed the Focal Length to 24mm, and Filmback Width to 22.3mm x 14.9mm using the Survey data provided. This consequentially changed my Pixel Aspect, so I adjusted it back to 1.

To make the playback much smoother, I click on Export Buffer Compression file.

I tracked over 60 points in the video, but deleted erratic trackings for a better Deviation Point.
After deleting, I had 50 tracked points left.

I then Calculated all from scratch (Alt+C) to get my current deviation.

To enable my Deviation browser, I go to Config > Horizonal pane > Deviation browser to enable the browser showing my current deviation.
In the Deviation browser menu, Under show point deviation curves, I select All Points.

I had a high deviation, to bring my deviation low, in the camera attribute editor, I changed the positional camera constraint from No constraint, to Fixed Camera Position Constraint as the this is a Nodal Shot. Then went to my parameters adjustment window and changed my Focal Length to Adjust. I also enabled Distortion and Quartic Distortion.

.
After every adjustment, I calculate all from scratch. I tried both Brute Force and Adaptive and found Adaptive gave me the best results.

 

My Deviation is now finally lower than 0.4 .

In the 3D Controls Interface, I picked 2 track points to add a Distance constraint corresponding to the acquired information from the survey data.
I also pick 3 tracked points on the ground and align them to XZ Plane then select one of the 3 chosen points to move to Origin point.
I then created Locators under Geo whilst in the 3D orientation interface. I also created a Cube object under 3D models tabs.

I snap the 3D model cube to my origin point and readjusted its position.

I switched to Line Up Controls to see how far off my tracked points are from the centre.

Here I increased the size of the box, making it bigger, as the original smaller size didn’t quite look right.

Finally, I export my Locators, 3d object, Camera and Undistortion ready for Nuke.

..

 

In Nuke
(p.s. Notes are provided in the images)

  
I load the sequence and import all required notes.

 

    

I draft a simple Distortion pipeline that I follow for the process as a guideline.

3D Equalizer




     


I Load my sequence into 3DE4, and change my Len settings and change the Frame Per Second to 25fps.

I then tracked over 50 points, but deleted a few erratic points and was left with 49 tracked points in total.

My deviation was initially ridiculously high when I first calculated all from scratch. My deviation was well over 1.




 






     


Using the Parameter adjustment window, I adjust my Focal Length, Distortion and quartic distort.

I try both Brute Force and Adaptive, but found adaptive to give me better result after recalculating multiple times.


 




     

My Deviation comes down to 0.6033 after the process is complete.






 




     

I line up my controls to see how far off the point my tracking is. They looked good.




 








As my sequence was longer than required, I cut out the erratic section at the beginning, by starting my frames from the 17th frame instead and recalculated all from scratch again, which brought it down to 0.6016.




 




     .

Using my survey data, I add a Distance constraint for the wall Ledge above.




 






     

To do this, whilst in the 3D Orientation controls interface, I select the corresponding points in my scene and then I go to Constraints, and select Create Distance constraints and in put in the measurement. This adjusts the scenes.


 




     

I then select 3 Tracked points in my scene corresponding to the ground and align them to the XZ Plane.




 




     .

I select one of the 3 points I aligned to the XZ plane and moved this point to my Origin Point.

These actions then move all my points up, aligning my ground level visually.




 




     .




 




     

I then created Locators and scaled them up and down to preferred size, because they were initially tiny.




 




     .

I then create a Cube and snap it to my origin point.




 






     .

I rotate,vposition and resize the cube as needed.


 




     .

I check my line up control again to see how well my Cube sits in the scene.




 




     

I save my scene, then saved a 2nd version of the same scene as BAKED.




 








 






     


 








 




     




 




     




 




     




 






     




 








I then export all required elements for Nuke and Maya.

For Maya I exported the Mel Script.

For Nuke I exported the

– Camera

– Lens Distortion 

– and 3D Geometry (Cube and Locators) .


 


NUKE

(p.s. Notes are provided in the images)




     


I load the sequence, undistort it using the Lens distortion acquired from 3DE4 to ready it for Maya.


 




     




Then Write out the new sequence to send to Maya for further manipulation.

Midway through working, Maya crashes, and so does my Mel Script. I had to restart as the mel script was corrupted. I loaded up the Mel Script, saved it as an FBX and followed through the process after a few tries and fails. But worked well in the end.


 




     


 






     


 






     


 






     


Later in the process, i had a change of mind and swapped the rock idea I had with a character I modelled and rigged.


 






 




I repeated the same process I had initially carried out on the falling Boulder I created.

In summary, after placing and adjusting my MetalMan character as desired, I rendered it out with AOVS merged in the EXR sequence format to be further edited in NUKE.

I had initially did a quick roto manually, but then I swapped it out for a COPYCAT roto I did my self instead.
