Move the external force and constraint solvers from Fluvio to FluvioFX to support:

  • Turbulence
  • Surface tension
  • Buoyancy coefficients
  • Particle constraints for stabilizing the simulation currently things are fairly stable with just minimum density; a separate constraint solver seems excessive right now

Breaking changes/removals:

*NOTE: Make sure to back up all VFX graphs prior to install!* Graphs will probably break, and likely need to be fully rebuilt.

- Refactored all blocks and nodes. Instead of many different properties among the different steps, Fluid and SolverData VFX types are sent instead. This helps to reduce node clutter substantially
- Properties are no longer exposed by default. Instead, they are easily editable within the graph. Users can still expose individual properties, or entire fluids
- Simulation scale has been removed (fixed at 1.0, likely to be fully deleted later). This is no longer needed due to the VFX graph's improved handling of transforms
- Verlet integration is now the new default (see below). Physical properties for fluids will likely need to be adjusted slightly, but this change should help overall stability

Additions:

- Added additional integration methods–Stormer-Verlet and Velocity Verlet (#3). Also tweaked the Semi-implcit Euler integration to also integrate positons
- Implemented optional external force solvers, and built-in gravity (#2)
- The default FluvioFX graph now has a bunch of helpful sticky notes to help get started

Fixes:

- Particles no longer require a lifetime/alive attribute in order to be compatible with FluvioFX

Misc. changes:

- Updated solver to use the built-in mass attribute in preparation for multi-fluid simulation (#8)
- Added FluvioFX templates as a part of the install process
- Moved ReflectionHelpers to its own assembly to get rid of duplicate code
- Minor README updates
