Python Nodes
To be included in 2.65
PartIO IntegrationOverviewOpen Source particle library developed byWalt Disney Animation Studios
● Custom data layers● Read/Write several 3rd party formats
(Maya, Houdini, RenderMan)● Exchangeable backends● Integrated kd-Tree for neighbor lookups
PartIO IntegrationWhat will it be used for?● Runtime buffers
Particles in the current frame
● Point CacheResult of a baked simulation
● Import/ExportPipeline IntegrationFixed starting state
Bullet Physics
● Complex Rigid Body Collisions● Accurate dynamics solution
Lacking:● Customized collision response● Individual forces● Object Attributes
Nodes hook into Bullet for customization
Collision Nodes
Handled in separate node group/object nodes

Customized Forces
1. Global Force FieldsQuick effects: gravity, wind, ...
2. Individual ForcesGood for Living/Active things ("Actors", Boids)
3. InteractionComplex effects: Attraction, Flocking
Customized Forces:Node Design

Writing Nodes
C/C++:+ Fast- Requires patched builds or plugins (portability)- Complicated, many side effects, error prone
Python:+ Simple, adaptable syntax+ Runtime interpretation- Slow for large data sets
Writing Nodes"Modifier Language" ?Specialized scripting language for geometry
Combines advantages:● Runtime compilation and optimization● Lean syntax: no unnecessary code
Particle FX Library
Replaces hardcoded effects
● Simulations:Point Mass, Rigid Body, ...
● Emitters:Surface, Volume, Point, ...
● Colliders:Bounce, Kill, Stick, ...
