Support for Houdini 17.0 & 17.5 on Windows, macOS, and Linux.
Added extra information on the solver HDA to display the number active voxels as well as the current device being used.
Stability improvements with OpenCL.
Solver now throws proper warning and error messages when there is a failure or a preferred device could not be used.
Added a new HDA called Source Shapes that allows a user to source using basic primitives.
This is faster than direct volume sourcing.
User can add noise to breakup the shape of the source.
Forces can be added to the source such a directional force or turbulence noise.
Also works for collisions.
These shapes can be connected to the solver’s new fourth input.
You can use a mix of shape sources and volume sources.
Disturbance block size now defaults to referencing the division size using an expression.
Users can still override this.
Solver now outputs the number of active voxels as a detail attribute.
Adjusted reflective solver mode.
Reworks some of the operations to be more inline with the original paper that it’s based on.
A new example HIP file is included that compares the results of the different solver modes.
Turbulence noise model was producing artifacts.
This change does mean that previous simulations might look slightly different when run with this version.
