Sparse Pyro

introduction to pyro

• shelf tools create sourcing at geometry level, simulation DOP network, and output object to import simulation for rendering
• SOURCING: source volumes by rasterizing point attributes (for easy inspection) - Pyro Source, Pyro Source Spread, Attribute Noise, Volume Rasterize
• SIMULATION:
  • Smoke Object (Sparse) node creates simulation object with nescessary fields
  • Volume Source node imports and merges sources into fields
  • Pyro Solver (Sparse) node applies forces and evolves fluid fields
  • Smoke Solver: for simpler effects involving smoke, but NOT flames
• OUTPUT:
  • DOP I/O: pulls simulations results into SOPs for export and rendering. Can cache geometry for quick playback but cleans out visualization information.
  • Pyro Post-Process: manipulates visualization of imported pyro fields so viewport is close to final render, and prepares geometry for rendering
• Simulating in SOPs: Pyro Solver SOP is a SOP convenience wrapper of a pyro dynamics network, including built-in post-process node to prepare rendering. Sufficient for most simulations - see Simple FX shelf tab for examples:
  • Simple Billowy Smoke
  • Simple Fireball
  • Simple Spreading Fire

Flames Creates flames rising from the selected object.

Explosion Creates a large explosion rising from the selected object.

Fireball Creates a large explosion rising from the selected object.

Billowy Smoke Creates thick cloud-like smoke rising from the selected object.

Colored Smoke Turns the selected object into a turbulent source of colored smoke.

Add Color Turns on the color fields of a smoke object.

Wispy Smoke Creates thin smolder-like smoke rising from the selected object.

Candle Creates a smooth burning candle flame rising from the selected object.

Smokeless Flame Creates flames rising from the selected object, without any smoke (soot).

Dry Ice Creates dry ice fog falling from the selected object.

Volcano Creates a voluminous column of thick smoke, as from the rim of an erupting volcano.

Smoke Trail Generates a clustered simulation of smoke from an animated object.

Smoke Cluster Creates a clustered (partitioned) smoke simulation with multiple containers, using the selected point geometry as sources. This is useful for large or sparse sources, and for distributing simulations to a farm.

Pyro Cluster Creates a clustered (partitioned) pyro simulation with multiple containers, using the selected point geometry as sources. This is useful for large or sparse sources, and for distributing simulations to a farm.
