Stand Alone Complex
Three characters’ journey aboutHuman loneliness, finding his/her identity, and self-consciousness.
We as human beings have different Way to think about who we areAnd what we think about our life

Particle System? and Why?
:Thought process (think about a synapse)
:Three different (distinct) environment
:Interact with the footage (character)
:computer generated graphics techniques- basic terms?

Distinctive particle system (simple)

Distinctive particle system (advanced)

How?
:Maya’s embedded language called “MEL”Most tasks in Maya can be achieved through MEL
:What MEL can doCustomized UICycling workComputation art work

Generic Particle System in Maya
:Simple emitter and particle
:Preset effects – clouds, fire, hair, and etc
However,
:Doesn’t work properly….sometimesOrganic shapes – shatter (surface tracing)Generalized emitter and particle (behavior)
![Page 8: Stand Alone Complex: Open Your Eyes Juneui Soh Advisor – Prof. Striegnitz](https://reader036.vdocument.in/reader036/viewer/2022062517/56649ec55503460f94bd0034/html5/thumbnails/8.jpg)
Paint Effect Particle System (concept)
:Particle system as a brush
:Abstract particle system- easy to modify and control
:Painter effect – preset brushes in Photoshop
:User can draw a pre-programmed particle system- change values for variables
:Example!
![Page 9: Stand Alone Complex: Open Your Eyes Juneui Soh Advisor – Prof. Striegnitz](https://reader036.vdocument.in/reader036/viewer/2022062517/56649ec55503460f94bd0034/html5/thumbnails/9.jpg)
Paint Effect Particle System (pseudo code)
:Create generic emitter and particle
:Limit one emitter for few particles
:Swap particles with target shape (spring)
:Adjust particle’s character (generic)- conserve, distance btw particles, directions and etc
:Simulate each frame -> store as a paint brush
:Collision btw particles/ Depth sort for particles

Improved Shatter System (concept):Shatter system?
- once this shatter system hits the critical point, it becomes a particle system
:Generic algorithm: perfectly works on planes - uses surface tracing algorithm on vertices - horrible at organic shapes
- Speed - Shape
![Page 11: Stand Alone Complex: Open Your Eyes Juneui Soh Advisor – Prof. Striegnitz](https://reader036.vdocument.in/reader036/viewer/2022062517/56649ec55503460f94bd0034/html5/thumbnails/11.jpg)

Improved Shatter System (concept)
:Combine this concept with particle generating part!
:Cutting plane!

Summary of other past work
:Storyboard
:Greenscreen - footages
:Camera (HD – frame rate)

Future work (next term)
:Post-production (VFX/Edit)- color correction- touch up on particle system
- optical flare

Thanks a lot!
:Any question?

Improved Shatter System (pseudo code)•Generate first plane which cuts through the shape
make sure plane is in the shape boundary
Recurse:Generate random plane from previous plane
get a norm of the planecheck if n is bigger than the base casethen cuts it make separate parts a particle (Maya generic)and keep recursing
Base case: Flag >2^n ANDn of last generated plane’s distance to a surface is <
the shape’s size/7 (changeable) – avoid too small piece
Generated particles to nCloth: nucleus nodeeach volumic particle won’t overlap (rigidbody concept)
