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)

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!

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

Right after using generic shatterSystem on a sphere

each part of spheregenerated by thegeneric shatter system

Detail pictures of the problem

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)
