The voxel size to use.
Smooth velocities after interpolating them from curves tangents.
The smoothing radius in voxels.
The number of times to perform smoothing.
Create the velocity volumes using this volume as a reference.
Activate Voxels by Reference Volume
Create velocity volume voxels in regions where the reference volume is active.
Match Reference Volume
Match the transform and voxel size of the reference volume.
Determine Voxel Size from Average Primitive Area
Set the voxel size to the square root of the average primitive area.
This is usually a good size for effects that require accurate volume data close to the surface.
The determined voxel size is scaled by this factor.
Activate Voxels by Surface
Create velocity volume voxels in a band around the second input’s surface geometry.
The width of the volume band on the exterior of the surface.
The width of the volume band on the interior of the surface.
Fill the interior of the surface with voxels.
Force the created velocities to be tangential to the surface. This only works within the surface band, specified by Interior Band and Exterior Band, not in regions activated by other means.
Direct velocities away from the surface. Setting this to
1.0 makes velocities point straight out of the surface.
It is possible to use negative values to direct velocities into the surface.
Look up curve tangents within a constant radius.
Find Minimum Number of Curves
Automatically compute an appropriate radius that will include at least the specified number of curves.
Sample radius values from a volume in the 3rd input.
The constant curve lookup radius.
Minimum Curves in Radius
The minimum number of curves to include.
The volume to sample radius values from.
A multiplier against the computed or sampled radius.
